Adenomyosis and Hormones: How to Eat to Support Your Body

Are your periods heavy enough to plan your week around, and painful enough to cancel plans? If you've finally been told it's adenomyosis, you probably have one question. What can I actually do?

Medical care comes first, and I'll come back to that. But food is something you get to choose three times a day, and that adds up. A thoughtful adenomyosis diet won't cure the condition, but it can support your hormones, help calm inflammation and refill what heavy bleeding takes out.

Here's what's happening, what the science honestly says, and what to put on your plate.

What is adenomyosis?

Adenomyosis is when cells similar to the lining of the uterus grow into its muscle wall. Around one in five women are thought to have it, most often between 30 and 50. Common signs are heavy, long or painful periods, pain during sex and ongoing pelvic pain, though some women have no symptoms at all.

It's often confused with endometriosis, and they can occur together. The difference is location: with endometriosis, similar tissue grows outside the uterus. If that's your diagnosis, my post on an endometriosis diet for period pain and inflammation is the place to start.

Adenomyosis and oestrogen: the hormone link

Researchers describe adenomyosis as oestrogen-dependent and chronically inflammatory. In plain English, oestrogen helps the misplaced tissue grow. The tissue also tends to ignore progesterone, the hormone that usually keeps oestrogen in check. A 2026 University of Liverpool study also found ongoing inflammation in the affected tissue, which may help explain the pain and heavy bleeding.

That gives food two jobs. First, help your body clear used oestrogen. Second, keep inflammation down.

An honest note before we start: there's very little research on diet and adenomyosis specifically. Most of what we know comes from endometriosis studies and research on oestrogen and inflammation. Even that evidence is early. So think of this as sensible support, not a treatment.

The adenomyosis diet: what to eat

Pile on the greens and colourful plants

A 2024 systematic review found green leafy vegetables and fresh fruit were linked with a lower risk of endometriosis. Plants are packed with compounds that help calm inflammation (more in how to reduce inflammation with food). Aim for two colours at every meal. Think spinach and capsicum in your eggs, berries on your yoghurt, or a big handful of rocket with dinner.

Feed your gut, because it handles oestrogen

Your gut bacteria help regulate how much oestrogen circulates by making an enzyme that can switch back on oestrogen your liver has packed up for removal. A diverse, well-fed gut keeps this system in balance, and a calm gut matters too, as I explain in gut inflammation: the hidden driver. Legumes, oats, wholegrains, nuts, seeds and veg all help, which is one more reason fibre matters. Regular bowel movements matter too: that's one of the main exits for used oestrogen.

Go easier on red and processed meat

The same review linked higher red and processed meat intake with higher endometriosis risk. I'm not asking you to give up your Sunday roast. Just make fish, chicken, legumes and eggs your everyday proteins, and oily fish like salmon and sardines a twice-weekly habit.

Refill your iron

Heavy bleeding drains iron, and low iron can leave you tired, dizzy and breathless. Include red meat in modest amounts, plus lentils, tofu and leafy greens with a source of vitamin C. Here's how to absorb iron better. If you're constantly exhausted, ask your GP for an iron test rather than guessing. (Tiredness has other hormonal causes too. I unpack them in why women over 35 can feel exhausted.)

Keep alcohol and ultra-processed foods as treats

They add to inflammation and give your liver more work. That doesn't mean never. A glass of wine with friends is good for the soul. For the bigger picture, see what drives oestrogen excess.

Work with your doctor, not instead of them

Adenomyosis can be managed with pain relief, hormone treatments and sometimes surgery. The right mix is very personal. See your GP or gynaecologist if your periods are heavy, painful or affecting daily life. Use food alongside their care, not as a replacement.

Painful, heavy periods don't stay at home either. They show up at work as lost focus and sick days, which is why menstrual health is part of the conversation in my corporate wellbeing programs.

Frequently asked questions

Can diet cure adenomyosis?

No. Diet can't cure adenomyosis or shrink the affected tissue. What it can do is support healthy oestrogen clearance, help manage inflammation and replace iron lost through heavy bleeding. Medical treatment from your GP or gynaecologist remains the foundation, with food as everyday support alongside it.

What foods should I avoid with adenomyosis?

There's no strict list, as evidence specific to adenomyosis is limited. Based on related research, it's sensible to limit processed and red meat, alcohol and ultra-processed foods, and build meals around vegetables, fruit, legumes, wholegrains and oily fish. Small, consistent changes beat a restrictive plan.

Is adenomyosis the same as endometriosis?

No, although they're related and can occur together. In adenomyosis, tissue similar to the uterine lining grows into the uterus's muscle wall. In endometriosis, it grows outside the uterus. Both are linked to oestrogen and inflammation, and both are diagnosed and managed by a doctor.

Can adenomyosis cause low iron?

Yes. Heavy menstrual bleeding is a common cause of iron deficiency and anaemia in women. Symptoms include tiredness, dizziness, breathlessness and pale skin. If you have heavy periods, ask your GP to check your iron levels before reaching for supplements.

Look after yourself, and be patient with your body. It's doing a lot.

Yours in good health and some dark chocolate 🍫
