Does having a hysterectomy help endometriosis? An honest answer

First: endometriosis and adenomyosis are not the same disease

This distinction is where most of the confusion, and most of the disappointing surgery, begins. Adenomyosis is endometrial-like tissue growing inside the muscular wall of the uterus itself. It causes heavy bleeding, a bulky tender uterus, dragging pelvic pain and often severe cramping. Endometriosis is lesions outside the uterus, driven by inflammation, neuroangiogenesis and local oestrogen production within the lesions themselves (Zondervan et al., 2020, New England Journal of Medicine).

Because adenomyosis lives in the uterus, a hysterectomy removes it completely and definitively. Because endometriosis does not, a hysterectomy does not touch it unless the lesions are separately excised. Around 20 to 80 per cent of women with endometriosis also have adenomyosis, depending on the imaging criteria used, which is exactly why some women feel dramatically better after hysterectomy and others feel no different at all (Chapron et al., 2019, Human Reproduction Update).

Hysterectomy is a cure for adenomyosis. It is not a cure for endometriosis. If nobody has told you which one you have — or that you might have both — that is the first conversation to have.

What the research actually shows

The data here is not ambiguous, it is just rarely quoted. Studies following women after hysterectomy for endometriosis-related pain consistently find a meaningful minority still in pain afterwards, and a proportion who need further surgery.

• In a large long-term cohort, roughly 15 per cent of women who had a hysterectomy with ovarian conservation for endometriosis required further surgery for persistent pain, compared with under 4 per cent when the ovaries were also removed (Shakiba et al., 2008, Obstetrics & Gynecology).
• Pain persists or recurs in a substantial subset regardless of ovarian status, because residual lesions outside the uterus continue to produce inflammation and can generate their own oestrogen through local aromatase activity (Bulun, 2009, New England Journal of Medicine).
• Where the surgeon performs thorough excision of all visible disease at the same time as hysterectomy, outcomes are markedly better than hysterectomy alone — the benefit comes from the excision, not the uterus removal (Pundir et al., 2017, Journal of Minimally Invasive Gynecology).
• Deep infiltrating endometriosis involving the bowel, ureters or rectovaginal septum requires specialist excision, often with a colorectal or urological surgeon present. A standard hysterectomy will leave this disease behind (Working group of ESGE, ESHRE and WES, 2020, Human Reproduction Open).

Why "take the ovaries too" is not automatically the right answer

Removing the ovaries (bilateral oophorectomy) does lower the recurrence rate, and for some women with severe, recurrent, oestrogen-driven disease it is the right decision. But it is a bigger trade than it is often presented as, and this is where I think mainstream advice and the functional and integrative view diverge most sharply.

Surgical menopause before the natural age is not the same as menopause arriving on its own. The drop is abrupt rather than gradual, and it is associated with higher long-term risks of osteoporosis, cardiovascular disease, cognitive decline and all-cause mortality when it happens before around age 45 and oestrogen is not replaced (Rocca et al., 2016, Menopause; Parker et al., 2013, Obstetrics & Gynecology).

The clinicians whose frameworks I follow most closely in women's hormonal health are unanimous on this point: if the ovaries come out young, hormone replacement is not a luxury, it is standard of care — and body-identical oestradiol with progesterone where indicated is the preferred form. The concern that replacing oestrogen will simply reignite endometriosis is understandable, but the evidence suggests recurrence risk after thorough excision is low, and untreated surgical menopause carries its own significant harms (Menopause Society, 2022).

If you are being offered oophorectomy under 45, ask what the hormone replacement plan is before you agree to the surgery — not afterwards.

The myth that needs to die: "hysterectomy cures endo"

I want to be careful here, because many gynaecologists are excellent and many are genuinely up to date. But the belief that hysterectomy cures endometriosis is still widespread, still repeated in consultations, and still leads women to consent to major irreversible surgery on a false premise.

The reason it persists is partly historical. Endometriosis was once thought to be simply displaced endometrium, so removing the source seemed logical. We now understand it as a chronic, systemic, inflammatory and immune-mediated condition with its own local hormone production, altered immune surveillance and central pain sensitisation (Zondervan et al., 2020; Symons et al., 2018, Trends in Molecular Medicine).

That reframing matters practically. It explains why some women have severe pain with minimal visible disease, why pain can persist after all lesions are removed, and why an approach that only addresses anatomy will always leave part of the picture untreated. It is also why the root-cause framing used across functional medicine — immune function, inflammatory load, gut health, oestrogen metabolism and detoxification, nervous system regulation — is not an alternative to surgery. It is the other half of the work.

When a hysterectomy genuinely is the right call

None of this is an argument against hysterectomy. I have seen women get their lives back after one. The point is that it should be chosen for the right reason.

• Confirmed or strongly suspected adenomyosis, where the uterus itself is the pain and bleeding generator.
• Heavy menstrual bleeding that has not responded to hormonal management, a progesterone-releasing IUS, or a properly investigated iron and thyroid workup.
• A bulky, tender, symptomatic uterus with dragging pain, pressure and bladder or bowel symptoms attributable to uterine size.
• Multiple failed conservative treatments, completed family, and a clear, informed decision — ideally with thorough excision of extrauterine endometriosis performed at the same operation.
• Coexisting pathology such as large fibroids or persistent atypical bleeding requiring definitive management.

What to do before you say yes

Surgery is easier to consent to than to undo. Before you sign, I would want you to have all of the following.

• A clear answer to: do I have endometriosis, adenomyosis, or both? Ask what imaging supports it — a skilled transvaginal ultrasound or pelvic MRI in experienced hands can identify adenomyosis and deep disease.
• The surgeon's plan for extrauterine disease. Will lesions be excised, not just ablated or left? Excision by an experienced endometriosis surgeon consistently outperforms superficial ablation for pain outcomes.
• Whether the operation is happening in a specialist endometriosis centre with colorectal and urological support available if deep disease is found.
• A written hormone plan if the ovaries are being removed, including which preparation, at what dose, and who will monitor it.
• Baseline bloods and data: full iron studies and ferritin, vitamin D, thyroid panel including antibodies, HbA1c, inflammatory markers, and a bone density baseline if oophorectomy is on the table. Anaemia and low vitamin D both worsen recovery.
• A second opinion if the first conversation felt rushed, or if the word "cure" was used. It is not rude to ask; it is a permanent decision.

The question is not "should I have a hysterectomy?" It is "what exactly is causing my pain, and does removing my uterus address that?"

The work that continues either way

Whether or not you have surgery, the inflammatory and immune drivers of endometriosis do not disappear because an organ did. This is where nutrition and lifestyle earn their place — not as a replacement for medical care, but as the ongoing management that surgery cannot provide.

• Lower the inflammatory load: oily fish, olive oil, a wide range of colourful plants, adequate protein at every meal, and a genuine reduction in ultra-processed food, industrial seed oils and alcohol.
• Support oestrogen clearance: cruciferous vegetables for phase one and two liver detoxification, adequate fibre for excretion, B vitamins and magnesium as cofactors, and a functioning bowel — daily, complete motions are non-negotiable for hormone clearance.
• Look after the gut: dysbiosis and impaired gut barrier function amplify systemic inflammation and affect how oestrogen is recirculated. Diversity of plants, fermented foods where tolerated, and treating any confirmed overgrowth all matter.
• Dairy, if you include it: full-fat, organic, from animals raised without added hormones. A2, sheep or goat dairy suits many women with endometriosis better than conventional cow's dairy, and some do better trialling a period without it entirely.
• Regulate the nervous system: central sensitisation is real in long-standing pelvic pain. Sleep, breathwork, pelvic floor physiotherapy, gentle consistent movement and genuine stress reduction change pain thresholds measurably.
• Keep testing: post-surgery is exactly when I want to see iron, vitamin D, thyroid and bone density tracked, particularly if the ovaries were removed.
