Abdominal pain is the major sign of endometriosis.
Other signs can be anything from painful periods and irregular menstrual bleeding to diarrhea and low energy levels. Sadly, infertility is often also a sign of the condition. Endometriosis can occur at anytime between the onset of puberty and the conclusion of menopause. The only positive way to diagnose endometriosis is by direct observation via a common technique known as laparoscopy. This technique allows surgeons to explore the abdominal area using a miniature camera that is inserted through a tiny incision in the abdomen.
