Endometriosis is a chronic condition in which tissue similar to the lining of the uterus grows outside the uterus. It can cause severe menstrual pain, chronic pelvic pain, heavy bleeding, fatigue, digestive symptoms, pain with sex, and infertility. There is currently no cure, and treatment usually focuses on managing symptoms and reducing long-term impact.
Nutrition cannot cure endometriosis. But because inflammation and oxidative stress are part of the condition, researchers are studying whether dietary patterns may help support overall health and quality of life for people living with endometriosis.
One eating pattern that has received attention is the Mediterranean diet. This way of eating emphasizes vegetables, fruits, legumes, whole grains, nuts, fish, and extra virgin olive oil as a primary source of fat. A 2023 study found that greater adherence to a Mediterranean diet was associated with reduced pain perception and changes in oxidative stress markers in women with endometriosis, though more research is needed before making firm treatment claims. [1]
Extra virgin olive oil is a cornerstone of the Mediterranean diet. It is rich in monounsaturated fats and contains naturally occurring compounds including vitamin E, squalene, and polyphenols such as oleocanthal, which are studied for antioxidant and anti-inflammatory activity.
Oleocanthal has attracted particular interest because it can inhibit COX-1 and COX-2 enzymes, pathways involved in inflammation that are also targeted by some nonsteroidal anti-inflammatory drugs. This does not mean olive oil works like medication or should replace medical treatment, but it helps explain why extra virgin olive oil is often included in anti-inflammatory eating patterns. [2]
Researchers are also studying whether oleocanthal may influence pathways involved in menstrual pain. A 2020 study in Nutrients examined extra virgin olive oil and oleocanthal in laboratory and animal models of uterine hypercontraction and pain. The researchers observed effects on prostaglandin-induced uterine contractions, oxidative stress, and pain-related signaling pathways. While this research is still in its early stages, the findings are encouraging because they suggest that oleocanthal may influence biological pathways involved in inflammation and pain signaling.
Research on dietary fat and endometriosis is still developing, but a 2023 review found that the relationship between total fat intake and endometriosis is unclear. The type of fat may matter more. The review notes that saturated fat and trans fat may be less favorable, while omega-3 polyunsaturated fats and monounsaturated fats are being studied for potentially more favorable effects on inflammation. [3]
Extra virgin olive oil is a practical everyday swap for butter, shortening, coconut oil, palm oil, or other fats higher in saturated fat. It is not a cure or a treatment by itself, but it can help move the overall diet toward a Mediterranean-style pattern.
Extra virgin olive oil will not cure endometriosis, shrink lesions, or replace medical care. But it is a smart, flavorful fat to use regularly as part of a Mediterranean-style diet—an eating pattern that may help support inflammatory balance, antioxidant intake, and overall well-being.
For people living with endometriosis, that kind of everyday support matters. Try using extra virgin olive oil in salad dressings, roasted vegetables, soups, beans, whole grains, eggs, fish, and even baked goods.
