About the study


Endometriosis is a common disease where tissue similar to the lining of the uterus grows outside on other organs, causing scarring and pain. Endometriosis may cause painful periods, heavy periods, pain during sex and when going to the toilet. Some women are so severely affected by the disease they struggle emotionally and physically with their everyday lives.

Very little is known about what causes endometriosis and who might be most at risk of developing the disease. A person’s genes, their family history, and their health and experiences during childhood and adolescence might tell us a lot about who is most likely to get endometriosis.

Aims of the study

The Genetic variants, Early Life exposures, and Longitudinal Endometriosis symptoms Study (GELLES) is planning to look at a person’s genes and health across their life. We want to find out more about why endometriosis develops so that women can be diagnosed earlier and have better treatments.
