A sudden hormonal crash can follow an operation that removes both ovaries. Unlike natural perimenopause, which usually unfolds over years, surgical menopause can begin quickly and feel more intense, so the first days after surgery matter as much as the operation itself.
What surgical menopause means
Surgical menopause usually happens when both ovaries are removed, or when surgery stops them working abruptly and hormone production falls sharply. NHS Wales defines the removal of both ovaries before the average age of natural menopause as a bilateral oophorectomy. This can be carried out during a hysterectomy to treat a range of medical conditions, as set out in the British Menopause Society’s toolkit for healthcare professionals, published in October 2024.
The body has little time to adapt. Symptoms can be particularly severe because of the sudden loss of ovarian function, including in women who are already post-menopausal. The same abrupt drop can also follow cancer treatment, and surgery and chemotherapy can bring on menopause earlier than it might otherwise have happened.
What can start straight after surgery
The Royal Free leaflet covers what is normal, what symptoms are likely, and what support is available afterwards. In practical terms, women can see hot flushes, night sweats, sleep disruption, mood changes, brain fog, reduced libido, vaginal dryness and vaginal discomfort. These symptoms can land all at once, which is why surgical menopause often feels more disorienting than the slower changes of natural perimenopause.
The emotional impact can be just as real as the physical one. Medically induced menopause can be difficult to process because most public discussion still focuses on menopause that happens naturally. A discharge leaflet gives a name to symptoms that otherwise can feel abrupt, unexplained and isolating.
Why HRT comes up early
In NHS care, hormone replacement therapy is often part of the conversation after surgical menopause. NHS guidance on HRT states that the benefits usually outweigh the risks for many women, and that recent evidence shows the risk of serious side effects is very low. HRT comes in several forms, including tablets, patches and gel.
For women who have had an early menopause, HRT can also protect bone health. The Royal Osteoporosis Society includes HRT among the options that can help prevent osteoporosis in the years around menopause and can be a good choice if someone needs treatment for both menopausal symptoms and bone protection. It is usually started before 60, because the balance of benefit and risk changes with age.
For women having risk-reduction surgery because of BRCA1 or BRCA2 gene mutations, NHS Wales has specific HRT after surgical menopause guidance. Those women are often making decisions about menopause treatment at the same time as cancer-risk reduction, and the follow-up needs to be coordinated rather than treated as a separate issue.
Questions to put to your NHS team
The most useful appointment after surgery is a practical one. Ask what symptoms are expected in your situation, whether HRT is suitable, and when it should start. If HRT is not appropriate, ask what non-hormonal support is available for flushes, sleep, vaginal symptoms and pain during sex.
A clear checklist for that follow-up appointment is:
- Which type of HRT, if any, do you recommend for me now
- If I cannot take HRT, what is the plan for symptom control
- What bone health follow-up do I need after surgical menopause
- Do I need a cardiovascular risk review after this operation
- Who should I contact if my mood, memory or anxiety symptoms worsen
- What support is available for vaginal dryness, discomfort and sex life changes
The next steps affect sleep, work, relationships and daily function.
Bone, heart and mental health are part of the same conversation
NICE originally published its menopause guideline NG23 on 12 November 2015, and an updated version was published in November 2024. The same long-term issues keep coming up: bone loss, cardiovascular risk and mental wellbeing.
Women generally have a lower risk of coronary heart disease before the menopause, but that risk increases afterwards, as the British Heart Foundation sets out. Sudden ovarian loss should trigger a proper cardiovascular conversation, not just a prescription discussion. Menopause can bring anxiety, low mood, memory and concentration problems, low energy, panic attacks, mood swings, low self-esteem and new fears or phobias, as the Menopause Charity notes.
If flushes are wrecking sleep, if low mood is affecting work, or if vaginal symptoms are affecting relationships, that is a reason to seek follow-up rather than waiting for the next routine check. The Royal Free leaflet frames those problems as part of surgical menopause, not as something to be managed alone.
Where the leaflet helps, and where follow-up matters
The Royal Free leaflet helps patients and families understand the terminology, recognise expected symptoms and know when to ask for more help. That is especially valuable after gynaecological surgery, cancer treatment or risk-reduction surgery, when the menopause can begin without the gradual warning signs of perimenopause.
But a leaflet cannot replace tailored follow-up. When menopause is medically induced, women often need support that goes beyond the standard conversation about naturally occurring menopause, a point also covered in Royal Marsden patient information. The RCOG published its patient leaflet on treatment for symptoms of the menopause in February 2018, alongside guidance on risk-reducing salpingo-oophorectomy and HRT below the age of natural menopause.
See your GP or NHS team if symptoms are severe, if they are affecting sleep or mental health, or if you have not been given a clear plan for HRT, bone health, heart health and follow-up.
