Changes in a Woman's Body During Menopause: Complete Support Guide
Last Updated: 15 October 2026

Menopause is a natural stage of life that brings changes to a woman's hormones, body and wellbeing. From hot flushes and disturbed sleep to changes in bone health, digestion, mood and vaginal comfort, understanding what happens during the menopause transition can help women make informed decisions about their health.
In this guide, insights on nutrition and lifestyle are provided by Yusra Serdaroglu Aydin MSc RD, Vivere's Head of Nutrition with a background in nutrition, food engineering and culinary arts. Her approach is grounded in science and shaped by a strong understanding of personalised nutrition and the human microbiome.
Clinical and hormonal information is informed by UK guidance from the NHS, the National Institute for Health and Care Excellence (NICE) and the British Menopause Society. Although menopause is not an illness, evidence-based menopause support in the UK can help women understand their symptoms, explore appropriate treatments and find an approach that suits their individual needs.
In One Sentence:
Menopause is a natural transition in which the ovaries produce less oestrogen and periods stop permanently, typically around the average age of 51 in the UK, with changes to temperature regulation, sleep, bones, heart health, vaginal and urinary health and mood that can be supported through lifestyle, nutrition and medical options.
Key Takeaways
What is menopause? Menopause is when periods stop permanently because ovarian hormone production declines, and it is usually confirmed after 12 months without a period when no other cause explains the change.
When does menopause happen in the UK? The average age is 51, although menopause usually occurs between 45 and 55 and perimenopause can begin several years earlier.
What changes can women expect? Common changes include hot flushes, night sweats, disturbed sleep, mood changes, brain fog, shifts in metabolism and body fat distribution, bone loss and vaginal or urinary symptoms.
Can diet and lifestyle help? A balanced diet containing calcium, vitamin D, protein, fibre and healthy fats, alongside regular movement and strength training, can support bones, muscles, heart health and general wellbeing.
What support is available? Options include hormone replacement therapy (HRT), local vaginal oestrogen, cognitive behavioural therapy (CBT), lifestyle changes and guidance from a GP or menopause specialist.
Changes in a Woman's Body During Menopause
Menopause affects several body systems because declining ovarian hormone production influences much more than the menstrual cycle. Women may notice physical, emotional and cognitive changes at different stages of the transition, with symptoms varying considerably in type, severity and duration.
What age does menopause happen in the UK?
The average age of menopause in the UK is 51, although most women experience it between the ages of 45 and 55. Perimenopause, the stage leading up to menopause, can start several years before periods stop completely. Some women experience menopause earlier because of medical treatment, surgery, genetic factors or other health circumstances.
What changes can I expect?
Menopause can affect temperature regulation, sleep, bones, muscles, cardiovascular health, digestion, vaginal and urinary tissues, mood and concentration. Not every woman experiences every symptom, and some notice relatively few changes while others find that symptoms significantly affect daily life.
Common changes include hot flushes, night sweats, fatigue, irregular periods, vaginal dryness, discomfort during sex, urinary symptoms, anxiety, irritability and difficulty concentrating. Changes in body composition may also occur, including a tendency to store more fat around the abdomen. These changes are not simply a matter of willpower or ageing alone. Hormonal changes, sleep disruption, lifestyle and other individual factors can all contribute.
Can these changes be supported?
Yes, many menopausal symptoms can be managed through a combination of lifestyle changes, nutrition, psychological support and medical treatment. The most suitable approach depends on a woman's symptoms, medical history, preferences and individual risk factors.
A GP can discuss evidence-based options, including HRT and treatments for specific symptoms. Nutrition and physical activity can help support long-term health, but they do not replace medical assessment when symptoms are severe, persistent or unusual.
What Are the Three Phases of Menopause?
The three phases are perimenopause, menopause and postmenopause, which describe the hormonal transition, the final menstrual period and the years that follow.
The NHS explains that menopause usually occurs between 45 and 55, with an average age of 51 in the UK [1]. The transition is different for everyone, so identifying which phase you are in involves considering your menstrual history, symptoms and circumstances rather than relying on age alone. For most otherwise healthy women aged 45 or over, menopause can be identified clinically from symptoms and menstrual changes without routine hormone tests. NICE guidance on menopause (NG23) also addresses early menopause and premature ovarian insufficiency [2].
When should you seek advice about early menopause? If you develop menopausal symptoms before the age of 45, speak to your GP. Symptoms before 40 require particular assessment because premature ovarian insufficiency may have implications for bone and cardiovascular health as well as fertility. NICE guidance on menopause (NG23) provides the clinical framework for assessment and management.
How Does Falling Oestrogen Affect the Body?
Oestrogen has roles in temperature regulation, bone maintenance, cardiovascular health, vaginal and urinary tissue, sleep and brain function, so declining levels can produce changes across several body systems.
Oestrogen is best known for its role in the menstrual cycle and reproductive health, but its effects extend throughout the body. During perimenopause, fluctuating levels can contribute to symptoms before hormone levels settle at a lower level after menopause.
Understanding these biological changes can help women recognise why symptoms occur and which forms of support may be useful. However, not every symptom experienced during midlife is caused by menopause, so persistent or unexplained changes should be assessed appropriately.
Hot flushes, night sweats and sleep
Hot flushes and night sweats are among the most common menopausal symptoms, affecting around three-quarters of women in some studies. These symptoms are known as vasomotor symptoms and can interfere with sleep, energy levels and mood.
Falling oestrogen affects the hypothalamus, the part of the brain involved in temperature control. This can make the body's temperature-regulation system more sensitive to small changes, triggering a sudden sensation of heat, sweating, flushing and sometimes palpitations. Night sweats can interrupt sleep repeatedly, leaving women tired and less able to manage stress during the day.
The Women’s Health Concern menopause factsheet explains common symptoms and management options [3]. Research from the SWAN study found that the median total duration of vasomotor symptoms was 7.4 years, although individual experiences vary considerably [4]. Symptoms may last for a shorter or longer period, so women do not need to assume that they must simply endure them.
"Small nutrition and lifestyle changes may help women identify and manage their individual hot flush triggers. Caffeine, alcohol and spicy foods can worsen symptoms for some people, particularly later in the day, so it may be worth easing back in the evening and noticing whether this makes a difference. Night sweats and broken sleep can feed into each other, so a cool bedroom, breathable nightwear and a lighter evening meal may also help create a more comfortable sleep routine."
Keeping a brief symptom diary can help identify patterns. If hot flushes or night sweats regularly disrupt sleep or daily activities, a GP can discuss treatments with stronger evidence, including HRT and appropriate non-hormonal options.
Bones and muscles
Declining oestrogen accelerates bone loss around menopause, potentially increasing the risk of osteoporosis and fractures later in life. Oestrogen helps maintain the balance between bone breakdown and bone formation. When levels fall, bone breakdown can become faster than rebuilding, reducing bone mineral density.
The Royal Osteoporosis Society explains the connection between menopause and bone health [5]. Research on bone loss around menopause also indicates that the rate of bone loss can accelerate sharply around the final menstrual period, particularly in the spine [6]. This makes the menopause transition an important time to consider long-term bone health.
Age-related muscle decline can occur alongside these changes, although it is not inevitable that women will experience substantial loss of strength. Adequate nutrition and regular strength training help support muscle function, balance and everyday mobility.
"Calcium, vitamin D and protein provide important nutritional support for bones and muscles. They are part of the raw materials the body needs to maintain these tissues, while resistance exercise provides a stimulus for muscles and bones to adapt. These changes happen gradually, which is why eating with bone health in mind earlier in life can put you in a stronger position as you move through menopause."
Women with risk factors for osteoporosis, a history of fragility fractures or concerns about bone health should ask their GP whether further assessment is appropriate.
Heart and metabolism
Menopause is associated with changes in cholesterol, body fat distribution and cardiovascular health, making heart health an important consideration during and after the transition.
Oestrogen influences blood vessels and aspects of cardiovascular risk. As hormone levels decline, some women experience an increase in LDL cholesterol, sometimes called the harmful type of cholesterol, alongside changes in how and where body fat is stored. These changes can occur alongside the effects of ageing, diet, physical activity, sleep and other health factors.
The British Heart Foundation explains how menopause relates to heart disease and cardiovascular risk [7]. An American Heart Association scientific statement also discusses changes in lipids, body fat distribution and vascular health during the menopause transition [8].
Menopause does not mean that heart disease is inevitable. A heart-healthy eating pattern, regular physical activity, avoiding smoking and addressing high blood pressure or cholesterol can all contribute to cardiovascular health. Women should continue routine health checks and discuss relevant risk factors with their GP.
Vaginal and urinary health
Lower oestrogen can thin and dry vaginal and urinary tissues, leading to symptoms that may persist after other menopausal symptoms improve.
This group of symptoms is often called genitourinary syndrome of menopause (GSM). It can include vaginal dryness, irritation, discomfort during sex, urinary urgency, a burning sensation when passing urine and recurrent urinary tract infections. These symptoms are common and can affect comfort, confidence, intimacy and quality of life.
NHS guidance on menopause symptoms describes vaginal and urinary changes associated with menopause [9]. Unlike hot flushes, which may improve over time, vaginal and urinary symptoms can persist without treatment.
Effective options are available, including vaginal moisturisers, lubricants and local vaginal oestrogen where appropriate. A GP can help identify the cause of symptoms and discuss suitable treatments. Urinary symptoms should not automatically be attributed to menopause, particularly when there is pain, blood in the urine, fever or other signs of infection.
Mood, memory and brain fog
Hormonal fluctuations during perimenopause can affect mood, anxiety, concentration and memory, making brain fog and irritability recognised experiences of the transition.
Oestrogen interacts with brain systems involved in mood regulation and cognitive function. During perimenopause, fluctuating hormone levels can coincide with low mood, anxiety, irritability, forgetfulness and difficulty concentrating. Broken sleep and night sweats can make these experiences more noticeable.
Brain fog is a descriptive term rather than a diagnosis, and it does not mean that a woman is losing her intelligence or inevitably developing dementia. These symptoms are not a personal failing, and they deserve attention when they affect everyday life.
Regular sleep routines, physical activity, a balanced diet and stress-management techniques may help support general wellbeing. Women experiencing persistent low mood, severe anxiety or significant memory problems should speak to a healthcare professional rather than assuming menopause is the only possible explanation.

Does Menopause Cause Bloating and Digestive Changes?
Menopause may coincide with bloating, trapped wind, changes in appetite and other digestive symptoms, although these changes can have several causes.
Oestrogen and progesterone influence processes involved in gut motility, fluid balance and digestive function. Hormonal fluctuations may contribute to changes in bowel habits or bloating for some women, while changes in diet, stress, sleep and activity can also affect digestion. The gut microbiome, the community of microorganisms living in the digestive tract, is another area of ongoing research in relation to health and hormonal transitions.
Menopause does not automatically mean that gut bacteria have become unbalanced or that a specific microbiome treatment is needed. Persistent bloating can have causes unrelated to menopause, so it is important not to dismiss symptoms as hormonal without considering other explanations.
Practical steps may include drinking enough water, gradually increasing fibre intake, eating a variety of plant foods and maintaining regular physical activity. If particular foods seem to trigger symptoms, a food and symptom diary may help identify patterns without unnecessarily restricting the diet.
Understanding your own gut health may be useful if digestive symptoms are a concern. Vivere gut microbiome testing is one option for exploring aspects of the gut microbiome, but test results should be interpreted carefully and cannot diagnose any disease that may cause bloating or replace medical assessment.
Speak to your GP if bloating is persistent, new or worsening, particularly if it occurs frequently or alongside abdominal pain, feeling full quickly, unexplained weight loss or changes in bowel habits. These symptoms deserve assessment rather than being assumed to be part of menopause.
A Comparative Summary of Menopausal Changes
The main menopausal changes affect different body systems, but each has potential support options that can be discussed with a healthcare professional.
How Can You Support Your Body Through Menopause?
You can support your body through menopause by combining suitable medical care with nutrition, regular movement, sleep support and psychological strategies tailored to your needs.
UK care is guided by NICE recommendations and NHS services, with GPs helping women assess symptoms and consider appropriate treatment. Lifestyle changes can support health throughout the transition, but they do not need to be used instead of effective medical care.
Dietary triggers and plant oestrogens
Reducing certain dietary triggers may help some women manage hot flushes, although triggers vary and dietary changes do not work equally well for everyone.
Caffeine, alcohol and spicy food are commonly reported triggers. If you suspect a connection, try reducing one at a time and monitor whether your symptoms change. Avoid unnecessary restrictions if a food does not appear to affect you.
Phytoestrogens are plant compounds with some similarities to oestrogen. They occur naturally in foods such as soya, beans and linseeds. A Cochrane review found no conclusive evidence that phytoestrogens reliably reduce hot flushes and night sweats, although some genistein-rich extracts (a substance derived from soy) showed a modest effect [10].
Foods containing phytoestrogens can form part of a balanced diet, but they should not be treated as a proven replacement for menopause treatment. Concentrated supplements may also differ from ordinary foods, so discuss them with a healthcare professional if you take medicines or have relevant health concerns.
Medical options, including HRT
Hormone replacement therapy (HRT) is an effective treatment for many menopausal symptoms because it replaces some of the oestrogen the body no longer produces at previous levels.
NICE guidance on HRT and menopause management recommends discussing the benefits and risks of treatment in the context of individual symptoms, medical history and preferences [2]. HRT can help relieve symptoms such as hot flushes and night sweats and may also help protect against bone loss while it is being used, although its suitability varies between individuals.
Treatment may include oestradiol, a form of oestrogen, and micronised progesterone or another progestogen when needed to protect the lining of the womb. Women who have had a hysterectomy may have different treatment requirements. Body-identical hormones are also available in regulated medicines. The term does not mean that every product marketed as natural or bioidentical has the same evidence or quality standards.
Local vaginal oestrogen can help manage vaginal and some urinary symptoms. It acts mainly in the local tissues and is different from systemic HRT, although the most appropriate option depends on the symptoms and clinical circumstances.
The benefits and risks of HRT vary according to factors such as age, health history, type of treatment and duration of use. A GP or menopause specialist can explain these considerations. Women seeking further information can also consult the British Menopause Society and Women's Health Concern for evidence-based guidance.
Talking therapies and CBT
Cognitive behavioural therapy (CBT) is a structured talking therapy that can help some women manage the impact of menopausal symptoms, including hot flushes, low mood and anxiety.
CBT focuses on recognising patterns in thoughts and behaviour and developing practical ways to respond to difficult experiences. It does not mean that menopausal symptoms are imaginary. Instead, it can help women manage their effects on sleep, confidence, stress and daily life.
NICE recommends considering CBT for certain menopause-related symptoms, and NHS Talking Therapies provides psychological treatment services in England [11]. Research on CBT for hot flushes and night sweats has found improvements in how troublesome these symptoms feel for some women compared with usual care [12].
In England, adults can often self-refer to NHS Talking Therapies without seeing a GP first. Availability and referral arrangements vary by service, and a GP can help identify appropriate support.
Movement and strength training
Regular physical activity supports bone and muscle health, cardiovascular fitness, mood and metabolic health during and after menopause.
The NHS recommends that adults aim for at least 150 minutes of moderate-intensity activity each week and muscle-strengthening activities on at least two days a week [13]. Activities can be spread throughout the week according to fitness, ability and personal circumstances.
Useful options include walking, dancing, cycling, resistance training and weight-bearing activities. Strength exercises using weights, resistance bands or body weight can help maintain muscle function. Weight-bearing and resistance activities can also support bone health, although the safest exercise programme depends on existing bone density, injuries and other medical conditions.
The LIFTMOR trial found that supervised high-intensity resistance and impact training improved bone mineral density and physical function in postmenopausal women with low bone mass [14]. This does not mean that every woman should begin high-intensity training. The study involved a structured, supervised programme, and exercise should be adapted to individual needs.
Yoga and other forms of movement may help with flexibility, balance and relaxation. The most useful activity is one that is appropriate for your health and that you can maintain consistently.
"Strength training is one of the most valuable and sometimes overlooked ways to support health during menopause. Working muscles against resistance, whether using weights, resistance bands or your own body weight, can help maintain muscle strength and support bone health. It can also make everyday activities feel easier, which may benefit energy levels and confidence."
Nutrition and lifestyle
A nutrient-rich, varied diet can support bones, muscles, heart health, gut function and energy levels during menopause.
Food is a practical way to provide the nutrients needed for long-term health, although no single food or diet can prevent every menopausal symptom. The NHS Eatwell Guide offers a useful framework for a balanced eating pattern, including fruit and vegetables, higher-fibre carbohydrates, protein sources, dairy or alternatives and unsaturated fats.
Calcium and vitamin D
Calcium and vitamin D are important for maintaining healthy bones. Calcium is found in dairy foods, calcium-fortified alternatives, some leafy green vegetables and tinned fish eaten with their bones, such as sardines. Vitamin D helps the body absorb calcium.
In the UK, sunlight exposure is limited during autumn and winter, so the NHS advises adults to consider taking a daily 10 microgram vitamin D supplement during these months. Some people are advised to take a supplement throughout the year because of limited sun exposure or other risk factors. Check NHS guidance on vitamin D and ask a healthcare professional if you are unsure what is appropriate.
Protein
Protein provides the building blocks needed to maintain muscle and other tissues. Useful sources include poultry, fish, eggs, dairy products, beans, lentils and tofu.
Including protein-containing foods regularly, alongside resistance exercise, can help support muscle maintenance. Needs vary according to age, activity, health and other individual circumstances.
Fibre and a variety of plants
Fibre supports normal digestion and can help maintain bowel regularity. Wholegrains, vegetables, fruit, beans, lentils, nuts and seeds provide fibre alongside a range of vitamins, minerals and other plant compounds.
Eating a variety of plant foods supports dietary diversity and provides nutrients that contribute to gut and cardiovascular health. Increase fibre gradually and drink enough water to help minimise digestive discomfort.
Heart-healthy fats
Unsaturated fats can form part of a heart-healthy diet. Sources include oily fish, nuts, seeds and olive oil. Replacing some saturated fats with unsaturated fats can help support healthy cholesterol levels.
A varied eating pattern that includes vegetables, fruit, wholegrains, pulses and suitable sources of healthy fats is generally more sustainable than relying on restrictive diets or individual supplements.
NAD+ and menopausal fatigue
NAD+, or nicotinamide adenine dinucleotide, is a coenzyme that cells use in processes involved in energy production and metabolism. NAD+ levels can decline with age, but the relationship between NAD+ and menopausal symptoms requires further research.
Menopausal fatigue and brain fog are often influenced by hormonal changes, disrupted sleep, stress and other health factors. Some people explore NAD+ supplements, including Vivere NAD+ capsules, but evidence that NAD+ supplements specifically improve menopause symptoms remains limited.
For this reason, food, sleep, regular movement and appropriate medical care should come first. If you are considering NAD+ supplements, speak to your GP or pharmacist, particularly if you take medicines or have an underlying health condition. Supplements should not be presented as a proven treatment for menopause or used as a replacement for an assessment of persistent fatigue.
When to See Your GP
You should speak to your GP if menopausal symptoms affect daily life, sleep, mood, relationships or your ability to work and carry out usual activities.
Support is available, and you do not have to wait until symptoms become severe before seeking help. A GP can assess whether symptoms are consistent with menopause, consider other possible causes and discuss suitable treatments.
Arrange an appointment if you feel persistently low, anxious or unable to cope, or if you experience significant vaginal or urinary symptoms, unexplained digestive changes or concerns about bone health. Bleeding after menopause, meaning bleeding after 12 months without a period, should always be assessed by a healthcare professional.
Seek urgent medical help for severe or rapidly worsening symptoms, or symptoms that may indicate an emergency. Menopause can explain many changes, but it should not be used to dismiss symptoms that need investigation.
Frequently Asked Questions
What are the first signs of perimenopause?
The first signs of perimenopause often include changes to periods, hot flushes, disturbed sleep and mood changes as hormone levels begin to fluctuate.
Periods may become irregular, shorter, longer, heavier or lighter. Some women also notice anxiety, irritability, night sweats, fatigue or brain fog. Perimenopause commonly begins during the mid-40s, although the timing varies. Symptoms can start before menstrual changes become obvious, and other health conditions can cause similar symptoms.
What is the average age of menopause in the UK?
The average age of menopause in the UK is 51, and menopause usually occurs between 45 and 55.
Menopause before 45 is described as early menopause, while premature ovarian insufficiency refers to loss of normal ovarian function before 40. If symptoms develop at an unusually young age, speak to your GP about assessment and appropriate support.
Can diet and lifestyle really help menopause symptoms?
Diet and lifestyle can support bone health, cardiovascular health, muscle strength, digestion and general wellbeing, although they do not eliminate every menopausal symptom.
A balanced diet containing calcium, vitamin D, protein, fibre, vegetables, fruit and healthy fats provides important nutrients. Regular strength training and aerobic activity support muscles, bones and heart health. Adjusting caffeine, alcohol or spicy food may help some women manage hot flushes. NHS guidance on vitamin D explains how supplementation can help maintain bone and muscle health when sunlight exposure is insufficient [15].
These measures can be used alongside medical treatment where appropriate. Women experiencing troublesome symptoms should not feel that they must rely on lifestyle changes alone.
Should I consider HRT?
HRT is an effective option for many women with menopausal symptoms, but whether it is suitable depends on symptoms, medical history, preferences and individual benefits and risks.
A GP or menopause specialist can explain the available preparations, including systemic HRT and local vaginal oestrogen, and help you make an informed decision. NICE guidance provides the UK clinical framework for assessing treatment options. The British Menopause Society and Women's Health Concern also provide patient information to support discussions with healthcare professionals.
How long do menopause symptoms last?
Menopause symptoms vary widely in duration, with some lasting a few years and others continuing for longer.
Hot flushes and night sweats can persist for several years, and research suggests that the median duration may be longer than many women expect. A period of around four to eight years is a useful broad guide for some women, but it is not a reliable prediction for an individual. Vaginal and urinary symptoms may persist after other symptoms improve, particularly without treatment.
Effective support is available at every stage, so women should seek advice whenever symptoms affect their wellbeing.
Nutritionist's Corner: Final Thoughts
“Understanding the connection between nutrition, lifestyle, hormones and the gut can help women make choices that support their health over time.
Falling oestrogen can affect temperature regulation, sleep, bones, muscles, heart health, vaginal comfort and mood. A balanced diet that includes calcium, vitamin D and protein supports bones and muscles, while fibre and a variety of plant foods contribute to gut and cardiovascular health. Healthy fats from foods such as oily fish, nuts, seeds and olive oil can also support a balanced eating pattern. If caffeine or alcohol makes hot flushes worse, reducing intake, particularly in the evening, may help.
Regular movement, including strength training, supports physical function, bone health and confidence. However, nutrition and lifestyle measures work best as part of a wider approach that considers medical care when needed. HRT, local vaginal oestrogen and talking therapies can provide effective support for suitable individuals. A conversation with your GP is a useful starting point if symptoms are affecting your quality of life or you are unsure which options are right for you.”
