Over 13 million women in the UK are affected by perimenopause or menopause at any one time — yet it remains widely misunderstood and undertreated. This guide covers everything from the earliest signs of perimenopause to the full range of HRT and non-hormonal treatment options available to you.

What is menopause?

Menopause is defined as the point at which a woman has not had a menstrual period for 12 consecutive months. It marks the natural end of the reproductive years and is caused by a decline in the ovaries' production of oestrogen and progesterone. In the UK, the average age of natural menopause is 51, but for some women it occurs in their 40s — and for a small percentage, earlier.

It is important to understand that menopause itself is a single moment — a date in retrospect. What most women actually experience is the prolonged transition leading up to it (perimenopause) and the years following (post-menopause). The symptoms, challenges, and treatment needs span all three stages.

Premature ovarian insufficiency (POI) — sometimes called premature menopause — affects around 1 in 100 women under 40. For these women, the health implications of long-term oestrogen deficiency are significant, and HRT is almost always recommended until at least the average age of natural menopause.

Understanding perimenopause

Perimenopause — the transitional phase before menopause — is often the most challenging period for women. It can begin in the mid-30s but most commonly starts in the mid-to-late 40s. During perimenopause, oestrogen levels fluctuate unpredictably before eventually declining. This hormonal instability is responsible for many of the most disruptive symptoms.

The average duration of perimenopause is four years, but it can last anywhere from a few months to more than a decade. Crucially, periods may still be occurring — even regularly — and a negative pregnancy test or "normal" blood results do not rule out perimenopause. This is why perimenopause can be challenging to identify without a focused conversation about symptoms.

How is perimenopause diagnosed?

The NICE guidelines (NG23, updated 2024) are clear: perimenopause is a clinical diagnosis based on symptoms, and blood tests are not routinely recommended for women over 45 because hormone levels fluctuate too much to be reliable. A thorough GP consultation, reviewing your symptoms, menstrual pattern, and health history, is the appropriate pathway.

For women under 45 with possible perimenopause symptoms, blood tests measuring FSH (follicle-stimulating hormone) may be useful, though even here, results must be interpreted alongside symptoms rather than in isolation.

The full spectrum of menopause symptoms

Most people are familiar with hot flushes and night sweats. Fewer realise that menopause can cause over 40 distinct symptoms across virtually every system in the body. This breadth is one reason menopause so frequently goes unrecognised — symptoms are attributed to stress, depression, anxiety, or simply "getting older."

Vasomotor symptoms (temperature regulation)

Hot flushes — sudden waves of heat, often affecting the face, neck and chest
Night sweats — intense sweating during sleep, often leading to waking and clothing changes
Cold flushes and chills
Heart palpitations — a racing, pounding, or irregular heartbeat

Psychological and cognitive symptoms

Brain fog — difficulty concentrating, word-finding difficulties, mental "sluggishness"
Memory lapses — short-term memory problems, forgetting words or tasks
Anxiety — sometimes occurring for the first time, or worsening existing anxiety
Low mood, depression, or emotional flatness
Irritability, mood swings, and a reduced tolerance for frustration
Panic attacks
Loss of confidence and self-esteem
Feeling overwhelmed or unable to cope

Sleep disturbance

Difficulty falling asleep (sleep onset insomnia)
Frequent waking during the night
Unrefreshing or poor-quality sleep
Early morning waking

Musculoskeletal symptoms

Joint pain and stiffness — particularly in the hands, knees, and hips
Muscle aches and general body pain
Reduced grip strength
Increased risk of osteoporosis and fractures (longer-term)
Crawling or tingling skin sensations (formication)

Urogenital symptoms

Vaginal dryness, soreness, or itching
Painful sex (dyspareunia)
Reduced libido
Recurrent urinary tract infections (UTIs)
Urinary urgency and frequency
Stress urinary incontinence
Changes in the labia and vaginal tissue (genitourinary syndrome of menopause)

Hair, skin, and body composition

Thinning hair or hair loss
Dry, thinning, or itchy skin
Loss of skin elasticity
Breast changes — increased tenderness or reduction in fullness
Weight gain, particularly around the abdomen
Changes in body odour
Brittle or weakened nails

Other physical symptoms

Fatigue — persistent, unrelenting tiredness
Headaches or migraines (new or worsening)
Digestive changes — bloating, nausea, altered bowel habits
Dry eyes and mouth
Tinnitus (ringing in the ears)
Altered taste or sense of smell
Gum and oral health changes
Electric shock sensations

"My symptoms were initially thought to be stress-related. Once perimenopause was identified and I started HRT, my mood lifted within weeks. Having time to talk through everything made all the difference."

HRT: types, safety, and how to choose

Hormone Replacement Therapy (HRT) replaces the oestrogen — and where appropriate, progesterone and testosterone — that decline during menopause. It is the most effective treatment for menopausal symptoms and is recommended as first-line treatment by NICE for women who have no contraindications.

The landscape of HRT has changed dramatically in the past decade. Modern preparations, particularly transdermal oestrogen combined with micronised progesterone, have a favourable safety profile and are supported by robust evidence.

Routes of administration

Patches: Stuck to the skin, changed once or twice weekly. Deliver a consistent dose of oestrogen and come in combined forms (with progestogen) or oestrogen-only.
Gels: Applied to the skin once daily, usually to the inner arm or thigh. Allow for flexible dose titration. One of the most popular forms in the UK.
Sprays: Applied to the inner forearm. Similar to gels in terms of absorption and flexibility.
Tablets: Oral oestrogen taken daily. Effective but carries a marginally higher risk of blood clots compared to transdermal routes because it passes through the liver.
Vaginal preparations: Pessaries, creams, or rings used locally for genitourinary symptoms. Can be used alongside systemic HRT or alone when systemic symptoms are not present.
Implants: Pellets implanted under the skin, typically in the abdomen. Provide steady hormone levels over several months. Less commonly used but an option for some.

Progesterone in HRT

Women who have a uterus need progesterone alongside oestrogen to protect the womb lining. The type of progesterone matters enormously. Synthetic progestogens (such as medroxyprogesterone acetate) carry a higher risk of breast cancer and are generally no longer first-line. Micronised progesterone (Utrogestan) — a body-identical form — is now preferred and is associated with a more favourable safety profile, as well as benefits for sleep.

Testosterone for women

Testosterone is increasingly recognised as an important part of menopause management. It is not routinely offered on the NHS but is available via specialist GPs. Low-dose testosterone (applied as a gel or cream to the skin) can significantly improve libido, energy, and cognitive symptoms in women who have not responded fully to oestrogen and progesterone alone.

Body-identical vs synthetic HRT

This distinction matters more than most patients — and many GPs — realise. Body-identical (also called bioidentical regulated) hormones are chemically identical to the hormones naturally produced by the body. They include:

Oestradiol — the form of oestrogen used in patches, gels, and sprays
Micronised progesterone (Utrogestan) — a body-identical progesterone
Testosterone — available as Testogel or compounded preparations

Synthetic HRT uses hormones that are similar to, but structurally different from, the body's own hormones. Older combined oral contraceptives and some older HRT preparations use synthetic progestogens. These carry a higher risk profile and are generally no longer recommended as first choice.

Note: "compounded bioidentical" HRT — bespoke preparations made by specialist pharmacies, often based on saliva tests — is different from regulated body-identical HRT. The British Menopause Society advises against compounded bioidentical HRT as there is insufficient evidence for its safety or efficacy, and the hormone tests used to guide it are not validated.

Is HRT safe?

The evidence base is now very clear. The 2002 Women's Health Initiative study — which generated widespread fear about HRT — used older synthetic hormones in an older age group, and its findings have since been substantially re-evaluated. Modern body-identical HRT, started within 10 years of the last period or before age 60, has a favourable benefit-risk profile for the vast majority of women.

For transdermal oestrogen with micronised progesterone specifically:

No increased risk of blood clots (venous thromboembolism)
No increased risk of stroke
Minimal and uncertain effect on breast cancer risk after 5 years
Significant benefits for bone density, cardiovascular health, and cognitive function

Every woman's risk profile is individual. A thorough consultation with a GP experienced in menopause care is the right way to assess the benefits and risks for your specific situation.

Non-hormonal and alternative treatments

HRT is not suitable for every woman. Those with a history of certain oestrogen-sensitive cancers, recent cardiovascular events, or who simply prefer not to use hormones have other options — though none match the efficacy of HRT for most symptoms.

Prescription non-hormonal options

SSRIs and SNRIs (e.g., venlafaxine, citalopram) — can reduce vasomotor symptoms and improve mood. Not as effective as HRT for hot flushes but a valid option for some women.
Clonidine — an older medication that can reduce hot flushes, though with a limited evidence base.
Gabapentin — used off-label for vasomotor symptoms, particularly night sweats.
Fezolinetant (Veoza) — a newer, non-hormonal NK3 receptor antagonist licensed in the UK specifically for vasomotor symptoms. A significant development for women who cannot take HRT.

Lifestyle and complementary approaches

Exercise: Regular aerobic and strength training exercise reduces hot flush frequency, improves mood, protects bone density, and supports cardiovascular health. It is one of the most evidence-backed non-pharmacological interventions.
Diet: A diet rich in phytoestrogens (found in soy, flaxseeds, legumes) may modestly reduce symptoms. Reducing alcohol and caffeine can help with hot flushes and sleep. Adequate calcium and vitamin D intake is critical for bone health.
Cognitive behavioural therapy (CBT): NICE recommends CBT for menopausal low mood and anxiety, and for reducing the distress caused by hot flushes.
Mindfulness and stress reduction: Can help with mood, sleep, and coping. Not a treatment for the underlying hormonal changes but valuable as a supportive approach.
Herbal remedies: Black cohosh has some evidence for reducing hot flushes in the short term. Red clover and evening primrose oil have been studied but evidence is inconsistent. Discuss any supplements with your GP, as some can interact with medications or are contraindicated in certain conditions.

When to see a specialist

Most women with menopause symptoms can be well managed by an experienced GP with a special interest in menopause. Consider seeking specialist input if:

You have a complex medical history (e.g., history of breast cancer, cardiovascular disease, blood clots) and need specialist risk assessment
Your symptoms are not improving adequately after several months of treatment
You have experienced early or premature menopause (under 40) and need specialist guidance on long-term HRT
You are experiencing significant sexual health or genitourinary symptoms not responding to standard treatment
You feel your concerns have not been addressed by your current healthcare provider

A GP with a special interest in menopause — such as a member of the British Menopause Society — can manage the vast majority of complex cases without requiring a referral to secondary care.

Private menopause clinic vs NHS

The NHS provides menopause care, and many GPs are excellent at managing it. However, appointment availability varies, and the standard 10-minute consultation can make it difficult to address the full complexity of menopause symptoms — a condition that benefits from nuance, shared decision-making, and time to listen.

Private menopause care offers several important advantages:

Time: Appointments of 30–45 minutes allow for thorough history-taking, examination, and a personalised treatment plan developed together.
Continuity: You see the same doctor every time, building a relationship and ensuring treatment is reviewed properly.
Access: Same-day or next-day appointments, without the need to fight for slots weeks in advance.
Expertise: A GP with a special interest and postgraduate training in menopause, rather than relying on a generalist with limited time.
Comprehensive care: Integrated blood tests, prescriptions, and follow-up — all within one clinic.

Private menopause care does not mean abandoning the NHS. Most women maintain their NHS registration and use private care for menopause management specifically — a practical arrangement that combines the best of both systems.

AtWell's approach to menopause care

AtWell's menopause clinic offers unhurried consultations with experienced GPs who understand the complexity of hormonal health. Our approach is rooted in three principles: listening properly, treating the whole person, and making evidence-based decisions together.

A first menopause consultation at AtWell lasts a minimum of 45 minutes. In that time, we cover:

A detailed symptom review using validated assessment tools
A thorough medical and family history, including cardiovascular and cancer risk factors
Discussion of your treatment preferences, concerns, and goals
Blood tests where clinically appropriate (hormone levels, thyroid function, bone health markers)
A personalised, evidence-based treatment plan — whether that means HRT, non-hormonal options, or a combination
Same-day prescriptions where appropriate
A structured follow-up plan, typically at 6 and 12 weeks initially

We prescribe body-identical HRT as our default approach and take care to explain every option, the evidence behind it, and how it applies to your specific situation. You will never be rushed, and you will never leave without understanding your plan.

Our women's health service extends beyond menopause, covering contraception, PCOS, endometriosis, PMS/PMDD, sexual health, and cervical screening — ensuring joined-up care across every stage of your life.

AtWell is based in Balsall Common, serving patients from Solihull, Knowle, Dorridge, Kenilworth, Coventry, and the wider West Midlands. Appointments are available same-day or next-day, with no referral needed.

"I had been suffering for two years and kept being told everything was normal. At AtWell, the doctor listened for the first time. They explained exactly what was happening and why. I started HRT and within six weeks I had my life back."
