What Endometriosis Is
Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus. It can be associated with pelvic pain, painful periods, pain with bowel movements or urination, fertility problems, and heavy menstrual bleeding.
Symptoms and severity vary widely. Medical treatment can include medication, surgery, or both, depending on symptoms, fertility goals, and other factors.
What Research Tells Us About Nutrition
The ESHRE endometriosis guideline concludes that studies of dietary interventions are limited and generally low quality. A specific “endometriosis diet” has not been established as a treatment.
A 2025 umbrella review likewise found that nutrition research remains heterogeneous and generally low-certainty. A balanced eating pattern can still help meet overall nutrient needs, while iron status may deserve attention when heavy menstrual bleeding is present and gastrointestinal symptoms may require individualized strategies.
Foods and Nutrients Discussed in the Evidence
These foods are discussed for general nutrition quality and nutrient adequacy—not because they have been proven to treat endometriosis.
Vegetables and fruits
A varied produce intake supports overall nutrient and fiber intake.
Whole grains and fiber
Whole grains can support regularity and contribute minerals and B vitamins.
Omega-3-rich foods
Fish and some plant foods provide unsaturated fats that fit balanced eating patterns.
Iron-containing foods
Iron-rich foods may be relevant when heavy menstrual bleeding contributes to low iron.
Colorful fruit
Berries, citrus, and other fruit add vitamin C and other nutrients.

When Individualized Help Matters
Severe or worsening pelvic pain, heavy bleeding, infertility concerns, or symptoms affecting daily life deserve medical evaluation.
If you are considering a restrictive elimination diet because of gastrointestinal symptoms, a registered dietitian can help protect nutrient adequacy and determine whether the restriction is actually useful.
