Perimenopause is the transitional phase before menopause when oestrogen and progesterone levels begin to fluctuate and decline. It typically begins in the mid-to-late 40s, can last seven to nine years, and brings a wide range of symptoms — from hot flushes and disturbed sleep to low mood and brain fog. While a GP-led conversation about medical options (including HRT) is essential, evidence-informed nutrition choices may help support your general wellbeing throughout this transition.

Key takeaways

Perimenopause usually begins between 45 and 55 and can last seven to nine years or longer — affecting around 80% of women with varying symptoms.
Falling oestrogen accelerates bone loss; adequate calcium, vitamin D, and weight-bearing exercise are important throughout this life stage.
A Mediterranean-style diet rich in vegetables, wholegrains, oily fish, and olive oil may help support cardiovascular health as oestrogen’s protective effects lessen.
Some women find that including soya foods regularly may be associated with a difference in their experience of hot flushes — though responses vary and this is not a substitute for medical care.
Stabilising blood sugar through regular meals, reducing processed sugars, and limiting caffeine and alcohol may support more consistent energy and sleep.
Always speak with your GP about perimenopause symptoms — HRT and other medical options can only be discussed and prescribed by a doctor.

What is perimenopause and when does it start?

Perimenopause begins when hormonal changes and associated symptoms start to appear, but before periods have stopped altogether. According to the NHS, it most commonly affects women between the ages of 45 and 55, though it can begin earlier — in some cases in the late 30s or early 40s.

The transition ends when a woman has not had a period for 12 consecutive months, which is the point clinically defined as menopause. The perimenopausal phase itself typically lasts around seven to nine years, though this varies considerably from one person to another.

During this time, oestrogen and progesterone do not decline in a smooth, gradual line — they fluctuate irregularly. This hormonal variability is largely why perimenopause symptoms can feel unpredictable and wide-ranging.

What are the most common perimenopause symptoms?

The NHS documents more than 15 distinct symptoms associated with perimenopause, and the British Dietetic Association (BDA) estimates that around 80% of women will experience at least some of them. Symptoms range from mild and barely noticeable to significantly disruptive to daily life.

Physical symptoms commonly reported include:

Hot flushes (experienced by around 40% of women in perimenopause)
Night sweats (around 17%)
Sleep disturbance and insomnia (around 16%, though some estimates are considerably higher)
Changes to periods — heavier, lighter, more or less frequent
Vaginal dryness and discomfort
Increased urinary frequency or urinary tract infections (UTIs)
Palpitations
Joint and muscle aches
Headaches
Hair thinning and changes to skin
Weight changes, particularly around the abdomen
Reduced libido

Psychological and cognitive symptoms can include low mood, anxiety, irritability, brain fog, and difficulty with memory and concentration. The NHS notes that women from Black ethnic backgrounds are more likely to experience hot flushes that are more severe and last longer — a reminder that perimenopause is not a one-size-fits-all experience.

If you are experiencing symptoms that feel related to perimenopause, speaking with your GP is the right starting point. A diagnosis and discussion of all appropriate options — including HRT — can only happen within a medical consultation.

Why bone health matters during perimenopause

One of the longer-term health considerations during perimenopause is bone density. Oestrogen plays a key role in maintaining bone strength, and as levels decline during the perimenopausal years, the rate of bone loss accelerates. This raises the longer-term risk of osteoporosis — though the degree of risk varies between individuals.

The NHS recommends that adults aim for 700mg of calcium per day, alongside 10 micrograms (400 IU) of vitamin D. While there are no specific calcium recommendations unique to the menopause transition, the NHS notes that “a healthy balanced diet, including calcium, summer sunlight, and vitamin D supplements, will help slow down the rate of bone loss.”

Good dietary sources of calcium include:

Dairy products (milk, yoghurt, cheese)
Green leafy vegetables such as broccoli and kale
Canned fish with bones (sardines, pilchards)
Fortified plant-based milks and breads
Almonds and other nuts

Because it is difficult to obtain sufficient vitamin D from food alone — particularly in the UK — the NHS advises everyone to consider a 10 microgram supplement, especially between October and March. Spending time outdoors in summer sunlight also supports vitamin D status.

Weight-bearing and resistance exercise (such as walking, yoga, or strength training) is also associated with supporting bone density and is worth discussing with your GP or a fitness professional. NICE’s updated menopause guideline NG23 (last updated April 2026) recommends that healthcare professionals discuss bone health and provide relevant advice at review appointments.

How does perimenopause affect cardiovascular health?

Before the menopause transition, oestrogen has a protective effect on the cardiovascular system. As the British Heart Foundation (BHF) explains: “Oestrogen helps to control your cholesterol levels and reduces the risk of fat building up in your arteries.” As oestrogen levels fall, this protection diminishes — which is why the perimenopausal years are a relevant time to pay attention to heart and circulatory wellbeing.

The BDA also notes that metabolic rate drops by approximately 10% around the time of menopause, and that central weight gain during this phase is associated with increased risks for both type 2 diabetes and cardiovascular disease.

From a nutritional perspective, dietary choices that may help support cardiovascular health during perimenopause include:

Eating plenty of vegetables, fruit, and wholegrains
Including oily fish (such as salmon, mackerel, and sardines) two to three times per week for omega-3 fatty acids
Choosing olive oil or rapeseed oil as your main cooking oil
Reducing saturated fat (found in processed foods, pastries, and fatty meats) and salt
Keeping alcohol within the recommended limit of 14 units per week, spread across the week
Avoiding smoking

The BHF notes that plant stanols and sterols (found in fortified spreads and dairy products) may also be worth considering if cholesterol levels are elevated — though this is something to explore with your GP.

Can soya foods and phytoestrogens help with hot flushes?

You may have heard that soya foods can help with hot flushes. The science here is nuanced and worth understanding clearly.

Soya beans, tofu, edamame, soya milk, and linseeds contain plant compounds called phytoestrogens (specifically isoflavones), which are structurally similar to oestrogen and may have a mild oestrogen-like effect in the body. The BDA notes that research from 2012 reported consuming soya isoflavones was associated with at least a 20% reduction in the frequency and severity of hot flushes for some women — but emphasises that these effects are “less potent than HRT” and that “research is ongoing.”

The BDA’s own framing is careful: “plant oestrogens may help (but they aren’t a given).” Some women find that including soya foods regularly as part of a balanced diet is associated with a difference in their experience of hot flushes — though responses vary considerably from person to person. If you’d like to trial this approach, the BDA recommends including soya foods daily for at least two to three months to assess your individual response.

One important caveat: anyone with a personal history of hormone-sensitive breast cancer should speak with their oncologist before increasing phytoestrogen-rich foods. And soya foods should always be seen as part of a broader, balanced diet — not as a standalone solution.

Supporting mood, energy, and sleep through nutrition

Fluctuating oestrogen levels can affect neurotransmitter activity, which is one reason why mood changes, anxiety, irritability, and low energy are so commonly reported during perimenopause. Disrupted sleep and night sweats compound this further.

While there is no single food or supplement that “fixes” these experiences, some general nutritional and lifestyle approaches may be associated with supporting more stable energy and mood:

Eat regularly and include protein at each meal. Supporting stable blood glucose by avoiding long gaps between meals and reducing processed sugars may be associated with more consistent energy levels throughout the day.
Prioritise plant diversity. The BDA recommends eating at least five different vegetables and fruit a day, and aiming for 30 different plant foods across the week to support gut microbiome health — which emerging research links to mood and hormonal metabolism.
Consider omega-3 fatty acids. Oily fish, walnuts, and flaxseed are good sources of omega-3 fatty acids, which have been associated with mood in some research — though the evidence specific to perimenopause remains mixed, and these foods should not be positioned as a way to address clinical depression. If you are experiencing significant low mood, please speak with your GP.
Limit known hot flush triggers. Both the NHS and BDA identify caffeine, alcohol, and spicy foods as common triggers for hot flushes in some women. Reducing these — particularly in the afternoon and evening — may also support sleep quality.

For low mood and anxiety that does not meet the threshold for a clinical diagnosis, NICE NG23 recommends Cognitive Behavioural Therapy (CBT) as an evidence-based option — and the NHS also endorses CBT for these perimenopausal symptoms. This is worth raising with your GP.

For sleep, maintaining a regular sleep schedule, keeping the bedroom cool, and practising good sleep hygiene can all be discussed as supportive measures. CBT for insomnia (CBT-I) is also recommended by NICE and is available on the NHS in some areas.

When should you see your GP about perimenopause?

If you are experiencing symptoms that you think may be related to perimenopause — whether physical, psychological, or cognitive — speaking with your GP is the right first step. Perimenopause is a medical transition, and your GP is best placed to discuss diagnosis and all appropriate options.

This includes a discussion about Hormone Replacement Therapy (HRT), which NICE NG23 (updated November 2024 and April 2026) recommends should be offered and discussed where appropriate. HRT is an evidence-based medical option that can only be prescribed and assessed by a doctor or appropriately qualified clinician. A nutritional therapist cannot and does not assess, prescribe, or advise on HRT.

Your GP may also discuss whether bone density assessment or cardiovascular risk evaluation is appropriate for you, depending on your personal history and risk factors.
