Menopause explained

What menopause actually is

Menopause itself is a single point in time. The phases around it are what most people actually mean when they say menopause.

The definitions

Menopause is defined as 12 consecutive months without a period. The day you reach that 12 month mark is technically your menopause. Perimenopause is the years leading up to this point. Postmenopause is the years afterward. The whole transition typically lasts 4 to 10 years from the first symptoms to settling into postmenopausal life.

When it happens

The average age of menopause in the UK is 51. Most women reach menopause between 45 and 55. Earlier menopause is called early menopause (40 to 45) or premature ovarian insufficiency (before 40). Later menopause is less commonly an issue. Family history influences timing. Smoking brings menopause forward by 1 to 2 years on average.

What is happening biologically

The ovaries have essentially run out of eggs and stopped responding to the hormonal signals from the brain. Oestrogen and progesterone production from the ovaries effectively ends. Small amounts of oestrogen continue to be produced by fat tissue and other sources. The hormonal environment is fundamentally different from reproductive years.

The variation between women

No two women have identical menopause experiences. Some women have mild symptoms over a short period. Others have significant symptoms for a decade. Some breeze through. Others find it the most demanding period of their lives. The variation is enormous and reflects genetics, life circumstances, individual biology and multiple other factors.

What menopause feels like

Menopausal symptoms extend far beyond hot flushes. The cultural focus on flushes alone misses much of what women actually experience.

The classic symptoms

Hot flushes and night sweats affect around 75 percent of women through the transition. Vaginal dryness affects 50 to 80 percent. Sleep disruption is almost universal at some point. These are the symptoms most people associate with menopause and they are common and often significant.

The mood and brain symptoms

Brain fog, difficulty concentrating, word finding problems, anxiety, irritability and low mood are all common. Women without previous mental health concerns can develop significant anxiety during perimenopause. The cognitive symptoms can be alarming because they feel like dementia but they are not. Symptoms typically improve in the years after menopause.

The physical symptoms

Joint aches, muscle aches, weight gain particularly around the abdomen, hair thinning, skin changes, palpitations, headaches and tinnitus all show up in menopause for some women. Many of these are not classically associated with menopause and women often do not realise they are part of the same picture.

The sexual symptoms

Vaginal dryness and discomfort, reduced libido and changes in arousal all commonly occur. Sex can become uncomfortable or stop being enjoyable. These symptoms often persist long after the more obvious flushes have settled. Most are treatable. Many women tolerate them for years before raising them with a GP.

What helps

Effective treatments exist for menopausal symptoms. The choice depends on severity, personal preference and individual circumstances.

HRT

Hormone replacement therapy remains the most effective treatment for menopausal symptoms. For most women in early menopause with significant symptoms, the benefits outweigh the risks. UK guidance has moved firmly toward prescribing HRT for women who need it. Modern HRT uses body identical hormones and is typically given through the skin (patches, gels or sprays) rather than as tablets. Speak to your GP.

Non hormonal treatments

Several non hormonal medications help specific symptoms. SSRIs and SNRIs reduce hot flushes for many women. Gabapentin can help. Specific medications address vaginal symptoms locally without systemic effects. Cognitive behavioural therapy adapted for menopausal symptoms has good evidence. These are options for women who cannot take HRT or prefer not to.

Lifestyle and the basics

Regular strength training, walking, adequate protein, sleep priority, limiting alcohol, managing stress and maintaining social connection all support wellbeing through menopause. None of these are substitutes for medical treatment when symptoms are significant but they support overall health and complement other treatments.

Supplements and alternative approaches

The supplement market has run far ahead of the evidence. Some women find modest benefit from phytoestrogens or herbal preparations but effects are typically much smaller than HRT. Be cautious of bold claims from supplement marketing. Speak to your GP before starting supplements, particularly if you take other medication.

Health after menopause

The years after menopause have specific health considerations that benefit from active attention. Many women feel substantially better after the transition settles.

Bone density

Bone loss accelerates significantly in the first 5 to 7 years after menopause. Adequate calcium and vitamin D, weight bearing exercise and where appropriate HRT all help. Women at higher risk of osteoporosis may need bone density scans and specific treatment. Speak to your GP about bone health if you have risk factors.

Cardiovascular health

Cardiovascular risk in women rises after menopause and approaches that of men of similar age. Active management of blood pressure, cholesterol and weight matters. NHS health checks every 5 years from age 40 catch many issues early. Lifestyle factors and where appropriate medication address modifiable risks.

Cancer screening

Postmenopausal women remain eligible for cervical screening until age 64. Breast screening continues to age 71 and women can self refer beyond this. Bowel screening starts at age 50. Attending screening when invited catches many cancers early. Postmenopausal bleeding always warrants prompt medical assessment.

The good news

Many women feel better in their late fifties and sixties than they did in their forties. The hormonal turbulence settles. Sleep often improves. Energy returns for many. The freedom from cycles and contraception is welcomed by many. This phase has its own challenges but is not a wind down. The years ahead can be excellent.
