Endometriosis causes tissue similar to the uterine lining to grow elsewhere. Weight gain may be an uncommon symptom of endometriosis.
Endometriosis commonly causes chronic pain, heavy, irregular periods, and infertility, and little research has explored why endometriosis might cause weight gain. Anyone with endometriosis who suspects that it is causing weight gain or making weight loss difficult should speak with a doctor.
It may be worth noting that other conditions, such as polycystic ovary syndrome (PCOS), can mimic the symptoms of endometriosis and lead to unexplained weight gain.
This article explores how endometriosis might cause weight gain and how to reach and maintain a healthy weight while living with the condition.

Medication for endometriosis

For example, treatment with a combined pill, which contains synthetic estrogen and progestin, and treatment with progestin alone
Most recently, researchers found that dienogest (Visanne), a type of oral progestin, can lead to weight gain and vaginal bleeding. And the injectable form of progestin-only birth control, Depo-Provera, can cause weight gain, as well.
Endometriosis and PCOS
PCOS causes some similar symptoms to endometriosis. It stems from a hormone imbalance and, like endometriosis, can cause painful periods.
Other symptoms of PCOS
- irregular or absent periods
- excessive body hair
- unexplained weight gain
- difficulty getting pregnant
- insulin resistance or diabetes
PCOS may cause weight gain due to insulin resistance and metabolic abnormalities.
It is also possible for people with endometriosis to have PCOS, as well. Anyone with irregular periods, painful periods, or difficulty conceiving should seek testing for both conditions.

- Having a healthy diet: Eating a variety of filling, lower-calorie foods, including lean proteins, vegetables, fruits, and whole grains, can help with weight management. Also, opting for high fiber and high protein foods may lead to fewer food cravings.
