Complications

Endometriosis is a chronic disease that is difficult to diagnose and to treat. Without treatment, endometriosis gets progressively worse in 65% to 80% of patients. Even with treatment, endometriosis continues to advance in 20% of patients. Cysts and implants may grow and spread to other parts of the pelvis, and in very severe cases, to the urinary or intestinal tracts. Eventually adhesions may form. These are dense, web-like structures of scar tissue that can attach to nearby organs and cause pain, infertility, and intestinal obstruction.

Pain

The most common problem for women with endometriosis is pain, which can significantly impair the quality of life. The pain experienced around menstruation can be so debilitating that up to 25% of women with the condition can be incapacitated for two to six days of each month. In severe cases, regular activities may be curtailed for up to two weeks per month. Sleeping problems have been reported in three quarters of patients, mostly due to pain.

Infertility

The medical literature indicates that endometriosis may account for as many as 30% of infertility cases. Some evidence suggests that between 30% and 50% of women with endometriosis are infertile. Often, however, it is difficult to determine if endometriosis is the primary cause of infertility, particularly in women have mild endometriosis. In an attempt to determine the chances for infertility with endometriosis, researchers have come up with a staging system based on findings during diagnostic surgery.

It should be noted that endometriosis rarely causes an absolute inability to conceive, but, nevertheless, it can contribute to it both directly and indirectly.
