What causes endometriosis?
No one knows for sure what causes this disease, but scientists have a number of theories. They know that endometriosis runs in families. If your mother or sister has endometriosis, you are six times more likely to get the disease than other women. So, one theory suggests that endometriosis is caused by genes. Another theory is that during a woman’s monthly periods, some endometrial tissue backs up into the abdomen through the fallopian tubes. This transplanted tissue then grows outside the uterus. Many researchers think a faulty immune system plays a part in endometriosis. In women with the disease, the immune system fails to find and destroy endometrial tissue growing outside of the uterus. Plus, a recent study shows that immune system disorders (health problems in which the body attacks itself) are more common in women with endometriosis. More research in this area may help doctors better understand and treat endometriosis.
One of the most puzzling conditions affecting women, the cause of endometriosis is not yet known. The most common theory, however, is that “retrograde menstruation” causes some of the menstrual tissue to back up through the fallopian tubes and implant in the abdomen. Endometrial cells in the menstrual fluid may then attach themselves to various sites in the pelvic cavity and cause growths.
