Menopause care

Surgical & Medical Menopause

After hysterectomy, ovary removal or cancer treatment

In short

Surgical menopause occurs when both ovaries are removed, causing an immediate and complete loss of ovarian hormones rather than a gradual decline. Medical menopause follows chemotherapy, radiotherapy or hormone-suppressing drugs. Symptoms are usually sudden and intense, and planning before treatment, where possible, materially improves the experience.

01Understand

Why sudden menopause feels different

Natural menopause happens over years, and the body adapts gradually to falling hormone levels. When both ovaries are removed, that adaptation period does not exist. Oestrogen, progesterone and a substantial proportion of circulating testosterone fall within days. Women commonly describe hot flushes beginning within the first week after surgery, alongside profound sleep disruption, mood change, joint pain and loss of libido, often while still recovering physically from the operation itself.

Removing the uterus alone, with the ovaries left in place, does not cause immediate menopause. Periods stop, but ovarian hormone production continues, although menopause may occur somewhat earlier than it otherwise would. This distinction is frequently misunderstood, and it changes both what to expect and what treatment is appropriate.

02Recognise

Medical menopause

Chemotherapy can damage ovarian follicles, sometimes temporarily and sometimes permanently, with the likelihood depending on the drugs used and age at treatment. Pelvic radiotherapy has a direct effect on ovarian tissue. GnRH analogues, used in endometriosis, fibroids and some cancer treatment, suppress ovarian function for as long as they are given, producing menopausal symptoms that are usually reversible when the drug stops.

Women in these situations often receive excellent oncological or gynaecological care while the menopausal consequences of that care go unaddressed. Symptoms are attributed to treatment in general and endured. They can be assessed and, in most cases, substantially improved, including for many women who cannot take systemic hormones.

One transition, many signals

Symptoms rarely arrive in isolation.

A useful assessment connects the pattern across sleep, temperature, mood, cycles, bone and heart health rather than treating each symptom as a separate problem.

Planning before surgery, where there is time

When bilateral oophorectomy is planned rather than urgent, a menopause consultation beforehand changes the experience considerably. It covers what symptoms to expect and when, whether hormone therapy can be started immediately after surgery, which route suits your history, what bone and cardiovascular protection will be needed, and what to do if the first plan does not work. Knowing what is coming, and having a prescription ready rather than beginning the search afterwards, is a meaningful difference.

Age at surgery matters. Removal of the ovaries well before the natural age of menopause carries long-term implications for bone density and cardiovascular health, and hormone replacement is usually recommended until at least the average age of natural menopause unless there is a specific reason not to. Where hormone therapy is contraindicated, the plan is built around non-hormonal treatment and structured long-term monitoring instead.

04Treat

After hormone-sensitive cancer

Women treated for breast or other hormone-sensitive cancers face menopausal symptoms that are often more severe than average, sometimes intensified by endocrine therapy such as tamoxifen or an aromatase inhibitor, while systemic hormone therapy is generally not an option. This group is too often told that nothing can be done.

In practice, several effective approaches exist and are considered in coordination with the oncology team: non-hormonal medicines for vasomotor symptoms, treatment for sleep and mood, cognitive behavioural approaches with good evidence for flushes, vaginal moisturisers and lubricants, and, in selected cases and after oncology discussion, low-dose local vaginal oestrogen. Every decision here is made jointly rather than unilaterally.

05Review

What follow-up involves

Care after surgical or medical menopause is longer-term than a single prescription. Reviews look at symptom control, dose adequacy, bone density where indicated, blood pressure and lipids, and sexual health, which is frequently affected and frequently unasked about. Testosterone is considered in specific circumstances, particularly after oophorectomy, where libido remains a problem despite adequate oestrogen.

Consultations are online, which is particularly useful for women recovering from surgery or attending frequent oncology appointments. In-person assessment is arranged where clinically required.

Common questions

Surgical & Medical Menopause: answers

Does a hysterectomy cause menopause?+

Not if the ovaries are left in place. Periods stop, but ovarian hormone production continues, though menopause may occur a little earlier than it otherwise would.

Can hormone therapy start immediately after ovary removal?+

In many cases yes, and where suitable it is often started very soon after surgery. Suitability depends on the reason for surgery and personal medical history.

Is treatment possible after breast cancer?+

Yes. Systemic hormone therapy is usually not appropriate, but non-hormonal medicines, behavioural approaches and local vaginal treatments are considered in coordination with the oncology team.

Is menopause from GnRH treatment permanent?+

Usually not. Ovarian suppression from GnRH analogues generally reverses after the medication is stopped, although recovery time varies.
