Endometriosis after menopause is possible, and it is more common than most people are told. The disease does not reliably stop when periods stop. A 2026 review in Current Opinion in Obstetrics and Gynecology estimates that 2 to 5% of postmenopausal people are still affected.
Endometriosis is tissue like the uterine lining growing outside the uterus. It bleeds with your cycle, irritates nearby tissue and leaves scar tissue and adhesions behind. Because it depends on oestrogen, the usual assumption is that menopause switches it off. For many women it does quieten down. For a minority it does not, and hormone therapy can sometimes wake it up again.
This page explains what happens to endometriosis after menopause, which symptoms still matter, how hormone therapy is chosen when you have both conditions, and when to ask for a referral. It also sets out what to ask before you agree to surgery.
What endometriosis after menopause actually means:
The implants behave like the lining of the womb. They respond to oestrogen, they bleed at the end of each cycle, and the blood has nowhere to go. That trapped blood causes inflammation, cysts, fibrosis and adhesions that can bind the bowel, bladder and pelvic floor together.
After menopause the ovaries stop producing oestrogen, so most implants shrink and the cyclical pain fades. What often remains is the structural damage: scarred tissue, a fixed ovary, a bowel loop stuck to the pelvic side wall. That damage can hurt without any active disease. This is why pain after menopause does not automatically mean the endometriosis is back.
Why menopause often eases symptoms:
Most women notice a clear improvement. The bloating, the heavy dragging pain before a period and the deep pain during sex usually settle within the first year or two after the last period.
The 2026 review describes postmenopausal endometriosis as under-recognised, with guidance for this group still limited. That is the honest position: the disease is less common after menopause, but it is not rare, and it is not gone.
Why it can still be active, or return:
Three things keep endometriosis alive after the ovaries have stopped working.
Fat tissue makes oestrogen. After menopause, fat, skin and other tissues convert adrenal hormones into small amounts of oestrogen. Some implants are sensitive enough to respond to those low levels.
Hormone therapy adds oestrogen back. This is the main driver of recurrence in treated women, and it is the reason the type of hormone therapy matters.
Surgery may have left disease behind. If lesions were not excised completely at hysterectomy, they can continue to cause symptoms.
Perimenopause is its own problem. Cycles become irregular and sometimes anovulatory, so oestrogen can run high without progesterone to balance it. Many women report that their endometriosis pain gets worse in the years before the last period, not better.
Signs of endometriosis after menopause:
The pattern to watch is pain that behaves the way the disease used to behave. Cyclical pelvic pain is the classic sign, even without bleeding. Other signals include deep pain during sex, painful bowel movements, pain when the bladder fills, bloating that comes and goes, and a dragging heaviness low in the pelvis.
Postmenopausal bleeding is different. Any bleeding after 12 months without a period needs assessment, whatever your history. NICE guidance treats it as a symptom that must be investigated, not watched.
A pelvic ultrasound is the usual first step. It can show an endometrioma, a cyst filled with old blood, and it can measure the ovaries. It cannot see small implants on the peritoneum, so a normal scan does not rule the disease out.
MRI is the better test when the question is how deep the disease goes, whether the bowel or ureter is involved, and whether a lesion looks suspicious. The 2026 review names MRI as the preferred imaging method for judging malignancy risk.
Laparoscopy with a biopsy remains the only way to confirm the diagnosis. A blood test called CA125 can be raised in endometriosis, but it is not a diagnostic test and a normal result means nothing either way.
Can HRT bring endometriosis back?
It can, and the risk is real enough that the regimen is chosen with it in mind. A 2026 review of postmenopausal endometriosis recommends hormone therapy after surgical or premature menopause, meaning before about age 45, because the bone and cardiovascular costs of going without oestrogen are high. For symptomatic natural menopause it says hormone therapy may be considered, with the caveat that the best regimen and duration are still unclear.
The same review prefers combined oestrogen-progestogen therapy or tibolone over oestrogen alone, because of the possible risk of recurrence or of malignant change in leftover implants. Oestrogen-only therapy is the pattern most often linked to reactivation in case reports.
That does not mean oestrogen is forbidden. It means the progestogen component is doing protective work, and it should not be dropped for convenience.
Which hormone therapy fits when you have both conditions:
| Option | What it contains | Why it may be chosen |
|---|---|---|
| Continuous combined HRT | oestrogen plus a progestogen every day | a progestogen may limit stimulation of implants left behind |
| Tibolone | one synthetic steroid with oestrogenic, progestogenic and androgenic effects | an alternative preferred in postmenopausal endometriosis |
| Oestrogen-only HRT | oestrogen with no progestogen | only for women without a uterus, and a higher concern if implants remain |
| Progestogen alone | a progestogen without oestrogen | for women who cannot take oestrogen safely |
A 2026 review in BJOG lists endometriosis among the situations where progestogen-only menopause therapy is a reasonable option, mainly for women with a contraindication to oestrogen. Micronised progesterone, taken in the evening, also helps sleep.
Transdermal oestrogen, given as a gel or patch, is often preferred when there is a clot risk. The route changes the risk profile, not the effect on endometriosis.
Treating pain once periods have stopped:
Surgery with excision of the lesions remains the diagnostic and treatment standard. A 2026 review notes that MRI is the preferred imaging test for spotting lesions and judging malignancy risk, while laparoscopy with histological confirmation settles the diagnosis.
Medical options are thinner than before menopause. Aromatase inhibitors, which block oestrogen production in fat and in the lesions themselves, show the most promise, but the review is explicit that the research is limited. Progestogens and pain management fill the gap.
Physiotherapy for the pelvic floor helps when pain has made the muscles guarded and tight. A trained physiotherapist can teach you to relax muscles that have been braced against pain for years, and that alone sometimes halves the ache.
Pain that has lasted years usually needs more than one approach. A pain clinic, psychological support for chronic pain, and a gynecologist who knows postmenopausal endometriosis are a reasonable team.
Hysterectomy, oophorectomy and what NICE says:
Removing the uterus and both ovaries is a big step, and NICE guideline NG73 is clear about how it should be discussed. Before surgery, the conversation must cover the chance of endometriosis coming back, the possibility of further surgery, and the benefits and risks of hormone replacement therapy after oophorectomy. NICE also says hysterectomy for endometriosis should be combined with excision of all visible lesions.
This is why the operation is not a guaranteed cure. If disease is left, it can still be stimulated later by hormone therapy. If everything is removed, you will need oestrogen for bone and heart protection, especially if you are under 45. Both halves of that trade-off belong in the conversation before the operation, not after it.
Heat on the lower abdomen relaxes the muscles that guard against pain. Gentle movement, such as walking or swimming, keeps the pelvic floor and bowel working without loading scar tissue. Sleep matters more than it sounds: poor sleep lowers the threshold at which the same pain feels unbearable.
If you take painkillers regularly, have that reviewed. Long-term use of anti-inflammatory drugs without a plan carries stomach and kidney risks, and it is easy to drift into years of daily tablets without anyone reassessing why.
Questions worth asking before you start:
- Which type of hormone therapy are you prescribing, and why this one?
- Does it include a progestogen, and how is it taken?
- How will we tell recurrence from scar tissue pain?
- What follow-up imaging do you plan, and when?
- If I have pain again, what is the next step?
When to see a doctor:
- Any vaginal bleeding after 12 months without a period, even a small amount.
- Pelvic pain that returns after years of being settled.
- Deep pain during sex that was not there before.
- Painful bowel movements or pain when passing urine that keeps coming back.
- A new pelvic mass, or bloating that does not settle.
- Pain that wakes you at night, or that is getting worse month by month.
- Symptoms that start or worsen after you begin hormone therapy.
