Summer Heat, PMS and PMOS
Why You May Feel More Tired, Puffy or Irritable on Holiday

Summer can be wonderful, but it can also be surprisingly hard on the body.

If you live with PCOS / PMOS, you may notice that hot weather or holidays leave you feeling more tired, puffy, bloated, irritable or emotionally sensitive than usual. You may sleep less well, crave more sugar, feel more swollen, struggle with exercise, or find that your PMS-type symptoms feel more intense.

This can be frustrating, especially when everyone else seems to be enjoying the sunshine with endless energy.

But there are good reasons why summer heat, travel and disrupted routines can affect how you feel. Hot weather changes fluid needs, it affects sleep quality, appetite, levels of movement and alcohol intake may changes, and all of this affects blood sugar patterns. For women with PMOS, who may already be more vulnerable to insulin resistance, inflammation, stress, and sleep disruption, those changes can feel more noticeable.

This does not mean you need a strict summer plan. It simply means your body may need a little more support when the weather is hot, your sleep is disrupted or your normal routine disappears.

Why Hot Weather Can Feel Harder with PMOS

Heat is a physiological stressor. Your body has to work harder to regulate temperature, circulate blood, produce sweat and keep fluid and electrolyte balance steady.

On a hot day, you may sweat more, sleep less deeply, drink less than you need, feel less hungry during the day, then become ravenous later. You may also be more likely to drink alcohol, eat later, move less during the hottest part of the day, or rely on quick snacks and iced coffees to keep going.

For someone with PMOS, this combination can affect energy, appetite, mood and digestion. If you are already prone to blood sugar dips, cravings or fatigue, then missing meals and relying on caffeine can make this worse. If you are prone to bloating or constipation, then dehydration and less movement can add to the problem. If your sleep is disrupted, you may feel more emotionally reactive and less resilient the next day.

Poor sleep is especially important. Research suggests that women with PCOS/PMOS may have higher rates of sleep disturbance, and circadian disruption may interact with insulin resistance, inflammation and hormonal regulation. In real life, this can look like waking unrefreshed, craving more sugar, feeling more anxious, struggling with motivation, or finding that PMS symptoms feel harder to manage.

Hot weather does not “cause” hormone imbalance on its own. But it can disrupt the foundations that help hormones, metabolism and mood feel steadier.

Fluid Retention, Bloating and Feeling Puffy

Many women notice that they feel more swollen or puffy in hot weather or after travelling, particularly flying. 

This can happen for several reasons. Heat can cause blood vessels to widen, and fluid may shift more easily into the tissues, especially around the hands, feet, ankles or legs. Sitting for long periods on flights, trains or car journeys can also reduce circulation and contribute to swelling. Alcohol, salty restaurant meals, dehydration, constipation and menstrual cycle changes can all add to that heavy, uncomfortable feeling.

This is not about “toxins” or needing a detox. It is usually about fluid balance, circulation, digestion, hormones and inflammation.

For women with PMOS, bloating and puffiness can feel especially distressing because body image can already be difficult. You may feel as though your body has changed overnight. You may feel uncomfortable in summer clothes or swimwear. You may feel tempted to restrict food to “fix it”.

But restriction often makes things worse. Under-eating can destabilise blood sugar, increase cravings, worsen constipation and heighten stress. A more supportive approach is to focus on hydration, movement, regular meals and fibre you tolerate.

Simple strategies can help. Drink regularly, especially in hot weather. Include potassium-rich foods such as potatoes, avocado, tomatoes, spinach, yoghurt and bananas if they suit you. Move your legs during long journeys. Walk in the morning or evening when it is cooler. Avoid sitting still for very long periods. Include vegetables, fruit, oats, seeds or other fibre sources that you tolerate, rather than suddenly increasing fibre dramatically.

If constipation is part of the picture, hydration and movement are often essential. Fibre needs fluid to work properly. More fibre without enough fluid can sometimes make bloating worse.

PMS, Mood and Blood Sugar in the Heat

Summer holidays can bring joy, but they can also bring more emotional load than people realise.

There may be body image worries, photos, swimwear, group meals, alcohol, family dynamics, disrupted sleep and less time alone. Add hot weather and blood sugar swings, and it is not surprising that mood can feel more fragile.

For women with PMOS, this matters because mental health symptoms, including anxiety and low mood, are more common. Blood sugar instability can also affect mood and appetite. When meals are delayed, protein is low, sleep is poor and caffeine is high, you may feel more irritable, tearful, anxious or craving-driven.

PMS-type symptoms may also feel more noticeable in the heat. This is not because heat directly “creates” PMS, but because the same foundations that support premenstrual wellbeing can become disrupted: sleep, hydration, blood sugar balance, bowel regularity, movement and stress management.

If you know your luteal phase is more sensitive, the week or two before your period may not be the best time to push your body hard in the heat, skip meals, drink more alcohol and sleep badly. Your body may need more steadiness, not more pressure.

A supportive luteal-phase holiday approach might include protein at breakfast, regular meals, mineral-rich foods, gentle movement, magnesium-rich foods such as nuts, seeds, oats and dark chocolate if tolerated, and earlier nights when you need them. You may also feel better choosing cooling movement such as swimming, walking in the shade, yoga or morning strength training rather than intense midday exercise in the heat.

Gentle Summer Strategies for PMOS Support
The goal is not to create another set of rules. It is to identify the small habits that give you the biggest return.

Hydration is one of the most important. In hot weather, you may need more fluid than usual, especially if you are sweating, walking more, travelling or drinking alcohol. Water-rich foods such as cucumber, tomatoes, watermelon, berries, citrus fruits, courgettes and yoghurt can help. Mineral-rich foods such as potatoes, avocado, spinach, nuts, seeds and dairy or fortified alternatives can support electrolyte intake.

Protein at breakfast can also make a noticeable difference. A breakfast based only on coffee, toast, pastries or fruit may not support energy for long. Eggs, Greek yoghurt, smoked salmon, tofu, nuts, seeds or a protein smoothie can help create a steadier foundation for the day.

Movement can be adjusted rather than abandoned. If it is too hot for your usual workout, try walking earlier in the morning, swimming, stretching, gentle cycling or a short strength session indoors. Exercise does not need to be extreme to be useful. For PMOS, consistent movement can support insulin sensitivity, mood and metabolic health, but it should be adapted to your environment and energy.

Sleep may need protecting more than usual. Keep the room as cool as possible, limit alcohol if it disrupts your sleep, get morning daylight, and consider an earlier night after a late one. If you are travelling across time zones, daylight exposure, meal timing and movement can help your body adjust.

Digestion also needs attention. If hot weather makes you less hungry, try not to skip meals all day and then eat a large late dinner. Lighter meals can still be balanced. Think Greek yoghurt with berries and seeds, eggs with vegetables, tuna or salmon salad with potatoes, chicken with rice and vegetables, hummus with oatcakes, or tofu with noodles and salad.

Hot weather and holidays can disrupt the foundations that help PMOS symptoms feel more stable. Sleep, hydration, meal timing, blood sugar balance, movement, digestion and stress all matter.

The good news is that you do not need perfection. You need a few anchors.

Drink regularly. Eat enough. Start the day with protein. Move in a way that suits the temperature. Keep your bowels moving. Protect your sleep when you can. Avoid using restriction as a response to feeling puffy or uncomfortable.

If you regularly feel exhausted, swollen, anxious, craving-driven or hormonally “off” during summer or while travelling, it may be worth looking at the bigger picture. PMOS symptoms can be influenced by insulin resistance, inflammation, gut health, stress, sleep, nutrient status, thyroid function and other health factors. If you’d like to know more, why not get in touch?

How Travel Can Impact Your PMOS Symptoms

Travelling can be exciting, restorative and much needed. But if you live with PCOS, now increasingly referred to as PMOS, you may also notice that your symptoms can feel harder to manage when you are away from home.

You might feel more bloated, more tired, more anxious around food choices, or more prone to cravings and blood sugar dips. Your sleep may become disrupted, your digestion may slow down, your usual movement routine may disappear, and meals may become less predictable.

This does not mean you have done anything wrong. Travel naturally changes the routines that often help the body feel more stable. For women with PCOS/PMOS, this can be particularly noticeable because the condition is closely linked with insulin resistance, inflammation, stress physiology, sleep disruption, gut health and appetite regulation.

The aim is not to control every meal or follow a perfect routine while you are away. Holidays and travel should still feel enjoyable! But understanding why symptoms can flare can help you plan in a way that feels supportive rather than restrictive.

Sleep, Stress and Circadian Rhythm Changes

Sleep is one of the first things to change when we travel. Early flights, late nights, different beds, unfamiliar environments, jet lag, alcohol, hotter rooms and disrupted meal timing can all affect sleep quality. Even short-term sleep disruption can influence appetite, energy, mood and blood sugar regulation.

This matters in PCOS/PMOS because many women are already more vulnerable to insulin resistance, energy dips, cravings and stress-related symptoms. Poor sleep can make the body less efficient at handling glucose, increase hunger hormones, reduce satiety signals and raise stress hormones such as cortisol. You may notice this as stronger cravings, feeling less satisfied after meals, waking tired, needing more caffeine, or feeling more emotionally reactive around food.

Circadian rhythm matters hugely when it comes to sleep. Your circadian rhythm is your internal body clock, which helps regulate sleep, digestion, temperature, hormone signalling and metabolic processes. Travel can disrupt this rhythm, especially when you cross time zones, eat meals much later than usual, or stay up later for several nights in a row. For women with PCOS/PMOS, this may be relevant because research suggests that circadian disruption and poorer sleep may interact with insulin resistance, inflammation and reproductive hormone regulation. This does not mean one late night will “ruin” your hormones. But it does help explain why several days of poor sleep, irregular meals and high stress can leave you feeling more symptomatic.

A supportive travel approach is not about being rigid. It may simply mean keeping a few anchors in place: getting morning daylight, eating a balanced breakfast when possible, avoiding too much caffeine late in the day, keeping alcohol moderate, and allowing one or two earlier nights if you start to feel depleted.

If you are travelling across time zones, morning light exposure, regular meal timing and gentle movement can all help your body adjust. If you are staying in the UK or Europe, the biggest issue may simply be later nights, less sleep and a more irregular rhythm. In that case, protecting your sleep on a few nights of the trip can make a real difference to how your energy, appetite and mood feel.

Gut Health and Digestive Disruption While Travelling

Digestive symptoms are very common when travelling. You may become constipated because you are sitting for longer, drinking less, eating less fibre, moving less, or ignoring the urge to go. Or you may experience looser stools, reflux or bloating because of richer food, alcohol, unfamiliar ingredients, stress, disrupted sleep or changes in routine.

For women with PCOS/PMOS, gut health is especially relevant. Research increasingly suggests that the gut microbiome may be involved in metabolic, inflammatory and hormonal pathways linked with PCOS. This is still an emerging area, and we should be careful not to overstate it, but it does support what many women experience clinically: when digestion is disrupted, symptoms such as fatigue, cravings, inflammation, skin changes and mood may also feel worse.

Travel often disrupts the foundations that support gut health. Meals may become lower in fibre and higher in refined carbohydrates. You may eat fewer vegetables, fewer plant foods and less fermented food. You may drink more alcohol, eat later, skip meals or graze through the day. Even if the food itself is enjoyable, the overall rhythm may be very different from what your gut is used to.

This can affect bowel habits, bloating and appetite. It may also affect blood sugar balance, because gut health and metabolic health are closely connected. Fibre-rich foods help support the gut microbiome and can also influence satiety and glucose response. When fibre drops and refined carbohydrates increase, many women notice more hunger, cravings and afternoon energy crashes.

However, it is important not to respond to this by becoming overly restrictive. The goal is not to avoid all holiday food. A more sustainable approach is to build in a few gut-supportive choices each day.

This might mean choosing cooked vegetables instead of relying only on bread and pastries, adding berries or seeds to breakfast, choosing oats when available, having a side salad or vegetables with dinner, or packing a few snacks you know your gut tolerates. It might also mean not suddenly increasing fibre dramatically on holiday, especially if you are prone to bloating or IBS symptoms. More fibre is not always better if your gut is sensitive and your routine is already disrupted.

For many women with PCOS/PMOS, the most helpful approach is consistency rather than perfection. A familiar breakfast, a daily walk, regular fluids and a few plant foods each day can help your digestion feel less overwhelmed by change.

Blood Sugar Balance on the Move

Blood sugar balance is one of the biggest reasons women with PCOS/PMOS can feel worse when travelling. Many women with PCOS/PMOS have some degree of insulin resistance, although this can vary from person to person. Insulin resistance means the body has to work harder to move glucose from the bloodstream into cells. This can contribute to energy dips, cravings, hunger, difficulty concentrating and feeling shaky or anxious if meals are delayed.

Travel days are often a perfect storm for blood sugar instability. You may skip breakfast because you are rushing. You may rely on coffee to get through the morning. You may have a pastry or cereal bar at the airport, then go several hours without a proper meal. By the time you do eat, you may be over-hungry, tired and more likely to choose something fast, sweet or very carb-heavy.

This is not a willpower issue. It is physiology.

When you under-eat early in the day, particularly if you miss protein, your appetite and cravings may intensify later. If you then combine that with poor sleep, stress, caffeine and disrupted routine, your body is more likely to look for quick energy.

A supportive travel strategy is to prioritise protein and fibre earlier in the day. This does not need to be complicated. At the airport, you might choose eggs, Greek yoghurt, smoked salmon, chicken, hummus, nuts, seeds or a more substantial sandwich with a decent filling. At a hotel breakfast, you might build your plate around eggs, yoghurt, fruit, oats, vegetables or smoked salmon rather than relying only on pastries, toast and juice.

If you are travelling by car or train, packing a few options can be very helpful. Oatcakes with cheese or nut butter, a protein bar with a simple ingredient list, Greek yoghurt, boiled eggs, nuts and fruit, hummus with crackers, or leftovers in a small container can all help reduce the likelihood of arriving somewhere exhausted and ravenous.

This does not mean you cannot enjoy holiday foods. It simply means that your body may cope better if you add some structure around them. For example, having ice cream after a balanced meal may feel very different from having it as lunch after a morning of coffee and no protein. Enjoying a pastry alongside yoghurt or eggs may feel more stable than having it alone with a sugary coffee.

For women with PCOS/PMOS, blood sugar balance is often less about restriction and more about pairing foods well. Protein, fibre-rich carbohydrates and healthy fats help meals feel more satisfying and can support steadier energy. This can also reduce the sense of anxiety or loss of control around food that many women experience when routines disappear.

Why Symptoms Can Feel Worse Emotionally Too

Travel can also bring up a lot emotionally. For some of us with PCOS/PMOS, holidays come with anxiety around clothes, body image, eating out, alcohol, photos, swimwear, group meals or feeling out of routine. If you have spent years being told to lose weight, cut carbs, avoid certain foods or control your body more strictly, travel can feel difficult.

It is worth saying clearly: you do not need to earn your holiday by dieting beforehand. You do not need to punish yourself afterwards. And you do not need to follow a perfect plan while you are away.

PMOS management should be supportive, not shame-based. A good travel routine should help you feel more stable, not make you feel anxious, restricted or guilty.

If food choices feel overwhelming, focus on one or two foundations rather than trying to control everything. For example, aim for protein at breakfast, water through the day, and a walk after dinner. That alone may be enough to support blood sugar, digestion and mood without turning your holiday into a set of rules.

How to Support Yourself Without Becoming Rigid

The most useful travel strategy is to decide which habits give you the biggest return.

For many women with PCOS/PMOS, this will be sleep, hydration, protein, meal timing and gentle movement. You do not need to do everything. You simply need enough consistency to stop your body feeling as though every foundation has disappeared at once.

Before you travel, think about your most likely trigger. Is it skipping breakfast? Eating late? Constipation? Alcohol? Anxiety around food? Cravings after poor sleep? Long gaps between meals? Once you know your pattern, you can plan around it.

If breakfast is your weak point, pack something or decide what you will choose at the airport or hotel. If constipation is common, prioritise fluids, movement and familiar fibre. If cravings become intense, avoid under-eating early in the day. If anxiety around food is the issue, decide on a few flexible principles rather than a list of strict rules.

This is about working with your body, not fighting it.

Travel will always involve some disruption. But with a few supportive anchors, you can reduce the likelihood of returning home feeling bloated, exhausted, inflamed and frustrated.

If you know that your PMOS symptoms flare when you travel, it may also be a sign that your everyday foundations need more support. Blood sugar instability, digestive symptoms, fatigue, cravings and stress sensitivity can all be influenced by nutrition, sleep, movement, gut health, inflammation and metabolic health.

Body Image, Confidence and PMOS: A Holistic Approach

Key Takeaways

• Body image worries are common in PMOS and are influenced by hormonal symptoms, weight changes, and lived experience
• Diet culture and restrictive eating patterns can worsen both physical and emotional symptoms in PMOS
• Sustainable habits and consistent nourishment support both metabolic health and self-trust
• Rebuilding a positive relationship with food takes time and requires a compassionate, non-restrictive approach
• Nutrition can support confidence, but it is one part of a broader, holistic approach to wellbeing

Body image can be one of the most challenging aspects of living with PMOS.

Changes in weight, skin, hair growth, and energy levels can all impact how we feel in our bodies. Alongside this, many of us with PMOS have spent years trying different diets, often with limited or short-term results, which can lead to frustration, self-doubt, and a loss of confidence.

It is important to acknowledge that these feelings are not superficial. They are shaped by both the physical realities of PMOS and the wider pressures around appearance, health, and body expectations. And never more so that in the current climate.  So, supporting our body image with PMOS requires a holistic approach, one that considers not only nutrition, but also mindset, habits, and – probably most importantly - self-compassion.

Why PMOS Impacts Body Image

PMOS affects multiple systems in the body, many of which can influence both appearance and self-perception.

Hormonal imbalances, particularly high androgens, can contribute to symptoms such as acne, hair thinning, or excess hair growth. Insulin resistance can make weight management more challenging, even when following dietary advice that may work for others. These changes often feel unpredictable and, at times, outside of your control.

Research has shown that individuals with PMOS are more likely to experience body dissatisfaction and reduced quality of life compared to those without the condition. This is not only due to physical symptoms, but also the emotional burden of managing a long-term condition.

Over time, repeated attempts to “fix” these symptoms through restrictive dieting can further impact self-esteem and body image.

It is therefore super important to try and shift the focus away from blame, and towards understanding the underlying drivers and supporting the body in a more sustainable way.

Moving Away from Diet Culture

Many of us with PMOS have been exposed to conflicting and often restrictive dietary advice.

Messages that focus on cutting out entire food groups, drastically reducing calories, or following rigid rules may initially feel like a solution. However, these approaches are often difficult to maintain and can contribute to cycles of restriction, cravings, and overeating.

From a physiological perspective, restrictive eating can also have unintended consequences. Under-fuelling may affect energy levels, mood, and hormonal balance, while irregular eating patterns can contribute to blood sugar instability, which may increase cravings and emotional eating behaviours.

Psychologically, diet culture can reinforce the belief that your body needs to be controlled or “fixed,” rather than supported. This can lead to feelings of guilt around food and a disconnection from hunger and fullness cues.

Moving away from this approach does not mean ignoring health. Instead, it involves shifting towards behaviours that are sustainable, flexible, and supportive of both physical and emotional wellbeing.

Rebuilding Trust in Food and Body

Rebuilding trust takes time, particularly if your relationship with food has been shaped by years of dieting or conflicting advice.

A helpful starting point is to focus on consistent nourishment.

Eating regular, balanced meals can help stabilise blood sugar, support energy levels, and reduce the likelihood of intense cravings or emotional eating. Including protein, fibre-rich carbohydrates, and healthy fats at meals provides both physical and psychological reassurance that your body is being adequately fuelled.

Over time, this consistency can help reduce the urgency around food and support a more settled relationship with eating.

It is also important to approach food with flexibility rather than rigidity.

Allowing a range of foods, rather than categorising them as “good” or “bad,” can help reduce feelings of guilt and support a more balanced approach. This is particularly important in PMOS, where overly restrictive patterns can often backfire.

Alongside nutrition, self-awareness and compassion play a key role.

Emotional eating is often linked to stress, fatigue, or unmet emotional needs, rather than a lack of discipline. Recognising these patterns without judgement can help create space for more supportive responses.

For example, asking what you need in that moment, whether that is rest, nourishment, or support, can be more helpful than focusing solely on the food itself.

It can also be helpful to consider the wider picture of wellbeing.

Sleep, stress management, movement, and social support all influence how you feel in your body. Nutrition works best when it is part of this broader, holistic approach.

Finally, confidence in PMOS is not built through achieving a specific outcome, but through developing trust in your ability to care for your body consistently.

This might look like:

• Eating regularly, even on busy days
• Choosing meals that support your energy
• Letting go of perfection and focusing on progress
• Speaking to yourself with more kindness

These shifts may feel small, but over time they can have a meaningful impact on both physical and emotional wellbeing.

Living with PMOS can be challenging, particularly when it affects how you feel in your own body. A holistic, compassionate approach can help you move away from cycles of restriction and towards a more supportive and sustainable way of eating and living.

If you are struggling with binge eating or feel that your relationship with food is becoming difficult to manage, it is important to know that support is available.

In the UK, organisations such as Beat Eating Disorders provide confidential helplines, online support, and guidance for both individuals and their families. You may also wish to speak with your GP, who can help you access appropriate NHS services, including specialist eating disorder support where needed.

At PMOS Clinics, we recognise that disordered eating patterns, including binge eating, can be closely linked to PMOS, particularly where there is a history of restrictive dieting, blood sugar instability, or body image concerns. We have a practitioner within our team who is specifically trained in supporting individuals with these challenges, using a compassionate, non-restrictive and evidence-based approach.

If this is something you are experiencing, you are not alone, and support is available.

The Food–Mood Connection in PMOS

Key Takeaways

• PMOS is associated with a higher prevalence of anxiety, low mood, and emotional eating, influenced by hormonal, metabolic, and psychological factors
• Blood sugar dysregulation and insulin resistance can contribute to mood swings, fatigue, and anxiety-like symptoms
• Neurotransmitter production depends on adequate intake of protein and key micronutrients such as B vitamins, magnesium, iron, and zinc
• Chronic low-grade inflammation and gut health may influence mood through the gut–brain axis
• Consistent, balanced nutrition can support emotional stability, reduce cravings, and improve resilience in PMOS

Living with PMOS is not only about managing physical symptoms such as irregular cycles, acne, or weight changes. Many people also experience anxiety, low mood, emotional eating, and challenges with body image.

Research suggests that individuals with PMOS are significantly more likely to experience symptoms of anxiety and depression compared to those without the condition. While the reasons for this are complex, they are not simply psychological. Hormonal imbalances, insulin resistance, inflammation, and the lived experience of PMOS can all contribute.

For many people, this can lead to a cycle of fatigue, low motivation, and feeling overwhelmed by food choices, particularly when trying to follow restrictive or unsustainable dietary advice.

Nutrition is not a standalone solution, but it is one area that can provide a stable and supportive foundation for both physical and emotional health.

Blood Sugar, Neurotransmitters and Mood

Insulin resistance is one of the central features of PMOS and has implications far beyond metabolic health.

When the body becomes less responsive to insulin, it can lead to higher circulating insulin levels and bigger fluctuations in blood glucose. These fluctuations can affect both energy levels and mood.

Rapid rises and falls in blood glucose can contribute to symptoms such as irritability, shakiness, fatigue, and difficulty concentrating. From a physiological perspective, when blood glucose drops, the body releases stress hormones such as adrenaline and cortisol to restore balance. While this is a protective mechanism, it can also produce sensations that feel very similar to anxiety.  And over time, repeated fluctuations in blood sugar may contribute to reduced resilience to stress and increased vulnerability to mood disturbances.

Alongside this, neurotransmitter production is heavily dependent on nutrient availability.

Serotonin, often associated with mood and emotional regulation, is synthesised from the amino acid tryptophan. Dopamine, which plays a role in motivation and reward, is derived from tyrosine. Both of these require adequate dietary protein, as well as cofactors such as B vitamins, iron, zinc, and magnesium.

Inadequate intake, irregular eating patterns, or chronic under-fuelling can therefore impact these pathways, potentially contributing to low mood, reduced motivation, and increased cravings.

This is particularly relevant in PMOS, where restrictive dieting and inconsistent eating patterns are common, often driven by weight concerns or conflicting dietary advice.

Inflammation, Gut Health and Mental Wellbeing

PMOS is associated with chronic low-grade inflammation, which may play a role in both physical symptoms and mental wellbeing.

Inflammatory markers have been found to be elevated in many individuals with PMOS, and emerging evidence suggests that inflammation may influence brain function and contribute to symptoms of depression and fatigue. While this relationship is still being explored, it highlights the importance of considering whole-body health when addressing mental wellbeing.

Gut health is another key factor.

The gut–brain axis is a complex, bidirectional communication system linking the gastrointestinal tract with the central nervous system. This communication occurs via neural, hormonal, and immune pathways.

The gut microbiota plays a role in the production and regulation of neurotransmitters, including serotonin, as well as in modulating inflammation and the stress response.

Alterations in gut microbiota composition have been observed in individuals with PMOS, which may influence both metabolic and psychological health outcomes. Factors such as low fibre intake, limited dietary diversity, stress, and previous antibiotic use may all contribute. If you would like to explore this further, you can read more in my March blog on the gut–hormone axis.

Supporting gut health through a varied, fibre-rich diet, including vegetables, whole grains, nuts, seeds, and, where appropriate, fermented foods, may help support both gut and mental health.

Practical Nutrition Foundations for Emotional Health

When you are feeling overwhelmed, it is essential that nutrition feels supportive rather than restrictive.

Many individuals with PMOS have experienced cycles of dieting, which can contribute to feelings of failure, guilt around food, and disconnection from hunger and fullness cues. A more sustainable approach focuses on building consistent, nourishing habits.

In practice, this often starts with regular, balanced meals.

Eating consistently, typically three meals per day, can help support blood sugar stability and reduce the likelihood of energy crashes that may trigger cravings or emotional eating. Each meal ideally includes a source of protein, fibre-rich carbohydrates, and healthy fats to support satiety and steady energy release.

Protein is particularly important, not only for blood sugar regulation but also for providing the building blocks for neurotransmitters involved in mood and motivation.

Fibre-rich carbohydrates support both glycaemic control and gut health, while healthy fats contribute to brain structure and hormone production.

Alongside this, reducing decision fatigue can be a powerful strategy. Keeping meals simple, repeating go-to options, and planning ahead where possible can help reduce overwhelm and support consistency.

It is also important to acknowledge the role of emotional eating.

Emotional eating is not a lack of discipline, but often a response to stress, fatigue, or unmet emotional needs. In PMOS, this can be further influenced by blood sugar fluctuations, hormonal changes, and body image concerns.

Addressing emotional eating requires a compassionate approach that considers both physical and psychological drivers. Supporting regular nourishment, stabilising blood sugar, and removing overly restrictive rules can help reduce the intensity and frequency of these patterns over time.

Burnout is another common experience.

When you are physically and emotionally depleted, it becomes much harder to make decisions around food, prepare meals, or prioritise self-care. In these situations, focusing on small, achievable changes, rather than aiming for perfection, is often the most effective approach.

Living with PMOS can feel overwhelming, particularly when both physical and emotional symptoms are present. Nutrition is just one piece of the puzzle, but it can provide a steady foundation to build from. If you would like support with your nutrition, why not book a call with us? We’d love to help.

Why Building Muscle Matters for PMOS

Key Takeaways

• Muscle tissue plays an important role in glucose metabolism and insulin sensitivity.
• Strength training can help maintain muscle mass and support metabolic health.
• Resistance exercise may also support bone health and physical function.
• A balanced exercise routine can include both strength training and aerobic movement.

Exercise is often recommended as part of managing polycystic ovary syndrome (PMOS), yet many of us feel unsure about where to start.

Cardio-based exercise such as walking, cycling or swimming is frequently suggested. While these forms of movement can be beneficial for overall health, high intensity endurance cardio can actually be detrimental to those of us with PMOS. Probably the most important component of exercise for PMOS is often overlooked: strength training.

Building and maintaining muscle mass may play a meaningful role in supporting metabolic health, improving insulin sensitivity and maintaining long-term physical wellbeing in people with PMOS.

Understanding how muscle interacts with hormones and metabolism can help explain why strength-based exercise may be particularly helpful.

The Role of Muscle in Metabolic Health

Skeletal muscle is one of the most metabolically active tissues in the body. It plays an important role in how glucose is used and stored.

After eating carbohydrates, glucose enters the bloodstream. Muscle tissue acts as one of the main sites where glucose can be taken up and used for energy.  For individuals with PMOS, insulin resistance is common. This means the body needs to produce more insulin to move glucose into cells effectively.

Strength training helps increase muscle mass and improve the ability of muscle cells to respond to insulin. Over time, this may support improved metabolic function.

Exercise can also stimulate glucose uptake independently of insulin. In simple terms, when muscles contract during activity, they can absorb glucose directly from the bloodstream.

This is one reason why regular movement is often recommended as part of a lifestyle approach to supporting metabolic health in PMOS.  You can read more about insulin resistance and PMOS in our article on understanding insulin resistance in PMOS.

Strength Training and Hormonal Balance

Strength-based exercise may also influence hormone regulation in several ways.

Research suggests that resistance training may help improve insulin sensitivity and body composition, both of which are important factors in PMOS management.

Muscle tissue also contributes to resting metabolic rate. This refers to the number of calories the body uses at rest to maintain essential functions.  Maintaining muscle mass can therefore help support energy balance over time.

Strength training may also support bone health. When muscles contract against resistance, they create mechanical stress on bones. This stimulus encourages bone remodelling and may help maintain bone density.

This connection between muscle and skeletal strength is particularly relevant when considering the long-term health of individuals with PMOS. You can learn more in our article on bone health and PMOS.

What Does Strength Training Look Like?

Strength training simply means using resistance to challenge muscles. This doesn’t necessarily require access to a gym. Resistance can come from bodyweight exercises, resistance bands, free weights or weight machines.

Examples of strength-based exercises include:

• Squats
• Lunges
• Push-ups
• Resistance band exercises
• Weight training with dumbbells or kettlebells

Research suggests incorporating strength training two to three times per week alongside other forms of movement such as walking or cycling can be beneficial in managing PMOS symptoms.

For those new to exercise, starting gradually is important. Short sessions focused on learning proper technique can be more beneficial than intense workouts that are difficult to maintain.

And consistency tends to be more important than intensity when building sustainable habits.

Overcoming Common Barriers

Many individuals with PMOS find starting to exercise really tough. Fatigue, joint discomfort, low motivation or previous negative experiences with dieting and exercise can all make movement feel really hard. But strength training does not need to be extreme or time consuming to be helpful.

Short sessions, supportive environments and gradual progress can help make movement more manageable and sustainable.

Focusing on how exercise supports energy, strength and long-term health, rather than solely weight loss, may also create a more positive relationship with movement.

Supporting Exercise Through Nutrition

Nutrition plays an important role in supporting muscle health and recovery.  Adequate protein intake provides the amino acids needed for muscle repair and maintenance. Many people with PMOS may benefit from distributing protein across meals throughout the day.

Micronutrients such as vitamin D, magnesium and omega-3 fatty acids may also support muscle function and recovery. Hydration and sufficient energy intake are also important, particularly for those increasing their activity levels.

You may find our PMOS-friendly recipes helpful if you are looking for practical meal ideas to support an active lifestyle.

A Balanced Approach to Movement

There is no single exercise approach that works for everyone with PMOS.

A balanced routine that includes strength training, low intensity aerobic movement and rest may help support metabolic health, muscle maintenance and overall wellbeing.

Finding forms of movement that feel enjoyable and sustainable is often the key to maintaining long-term habits.

Low Energy in PMOS? Start With Hydration

Hydration is one of the basic foundations of health, yet in PMOS it is rarely given the attention it deserves. Conversations more often centre around carbs, supplements, weight, or lab results. Water is reduced to a passing comment. Drink more. Stay hydrated. Aim for two litres.

In practice, however, fluid balance is not a background detail. It is part of the physiological environment in which hormones are produced, transported, signalled and cleared. When hydration is inconsistent, the effects are rarely dramatic enough to trigger medical concern, but they are often significant enough to influence daily symptoms such as fatigue, cravings, headaches, bloating and low mood.

For women already navigating the metabolic and hormonal complexity of PMOS, these small physiological stresses can accumulate. Understanding hydration as part of the wider gut–hormone conversation helps move it from generic lifestyle advice into something clinically meaningful and genuinely supportive.

The Link Between Hydration and Hormone Signalling

Hormones travel through the bloodstream to reach their target tissues. This process depends on stable blood volume, balanced electrolytes and effective cellular communication, all of which are influenced by hydration status. Even mild dehydration can subtly alter cardiovascular function, thermoregulation and cognitive performance.

In PMOS, where insulin signalling and appetite regulation are often already under pressure, these subtle shifts may be felt more clearly. Research shows that hydration status can influence blood sugar regulation, perceived energy, mood and concentration. Hydration is not a cure or a treatment for hormonal imbalance, but inadequate intake may add an additional burden to systems that are already working harder.

Our digestive system provides another important connection. Adequate fluid intake supports good production of digestive juices, how well our gut moves, and stool formation. These processes shape the gut environment that interacts with inflammation, microbial balance and hormone metabolism, themes explored in our discussion of the gut–hormone axis in PMOS.

When hydration is low, constipation and bloating are more likely to occur. In turn, discomfort may reduce appetite for fibre-rich foods, gradually influencing microbiome diversity and digestive resilience. This illustrates how hydration, gut health and hormonal regulation rarely operate in isolation. They are overlapping pieces of the same physiological picture.

Dehydration, Fatigue and Cravings

One of the most useful things to consider regarding hydration in PMOS is energy regulation. Mild dehydration commonly shows up as tiredness, headaches, dizziness or reduced concentration. These sensations are easily interpreted as hunger, particularly in the mid-afternoon when energy naturally dips.

For women managing insulin resistance, this misinterpretation matters. Responding to dehydration-related fatigue with quick carbs can reinforce the cycle of blood glucose spikes and crashes that many of us are trying to stabilise. Something as simple as improving fluid intake earlier in the day can therefore support steadier energy and clearer appetite signals, even without changing overall food intake.

There is also a neurological component. Thirst and hunger signals arise from closely related regions in the brain, which helps explain why they are so easily confused. Chronic under-hydration can therefore shape eating patterns in subtle but meaningful ways, contributing to grazing, sugar cravings or the sense of never quite feeling satisfied after meals.

Behaviour and routine play a significant role here. Busy work environments, long clinic shifts, caring responsibilities, commuting and high caffeine intake all make regular hydration more difficult than guidelines suggest. Many women realise late in the day that they haven’t drunk much water. Addressing hydration in PMOS is therefore less about strict targets and more about creating consistent daily habits.

Practical Hydration Strategies for PMOS

Hydration does not need to be complicated to be effective. In fact, the most helpful strategies are usually the simplest and most consistent.

Beginning the day with a glass of water helps restore hydration after overnight fasting and may gently stimulate digestion. Keeping water visible on a desk can subtly increase intake without conscious effort.

For those who struggle with plain water, small sensory changes often help. Lemon, cucumber, mint or herbal infusions can make fluids more appealing without relying on sugary drinks. Warm drinks can feel easier to tolerate for those with sensitive digestion, while cooler fluids may feel more refreshing during exercise or warmer weather.

Electrolyte balance is another quiet but relevant factor. Women who exercise regularly, sweat heavily, consume a lot of caffeine or experience frequent loose stools may benefit from paying attention to mineral intake alongside fluids. This does not usually require specialist products. Regular inclusion of vegetables, leafy greens, seeds and balanced meals often provides meaningful support.

Importantly, hydration should feel calm rather than pressured. Very high fluid intake is not necessary for most people and can occasionally feel uncomfortable or disruptive. Listening to thirst, observing urine colour and noticing energy levels often provide more realistic guidance than rigid rules.

A Small Habit With Wide Effects

Hydration will never be the most dramatic part of PMOS care, but it can be one of the most quietly influential. When fluid intake becomes more consistent, women frequently report steadier energy, fewer headaches, improved digestion and clearer appetite cues. These changes may appear modest, yet they create a more stable internal environment in which broader nutrition and lifestyle strategies can work more effectively.

Alongside balanced eating patterns, adequate fibre intake and support for gut health, hydration forms part of the everyday physiology that underpins hormonal wellbeing. You can explore these wider foundations in our article on balanced eating for PMOS, where the focus shifts from isolated nutrients to sustainable daily patterns.

Sometimes the most meaningful shifts in PMOS do not begin with complex interventions, but with simple habits repeated consistently. Hydration is one of those habits. Easy to overlook, yet powerful when supported.
