Some common symptoms of endometriosis are:

• Pelvic pain, especially during menstruation or just before it begins
  
  
• Pain during intercourse (dyspareunia)
  
  
• Painful urination (dysuria) or bowel movements (dyschezia) during menstruation
  
  
• Unusually heavy menstrual bleeding or any premenstrual bleeding
  
  
• Infertility
  
  
• Fatigue
   
  
• Blood in urine or stool
  
  
• Chronic pelvic pain or lower back pain

Some women with endometriosis have no symptoms. There is little correlation between symptoms and severity of the condition. Women with no symptoms may have advanced cases that are diagnosed only when they are tested for infertility. Women with relatively minor endometrial implants may experience debilitating pain.

Endometriosis symptoms are shared by other common and unrelated conditions, including irritable bowel syndrome (IBS), ovarian cysts, interstitial cystitis and pelvic inflammatory disease. A woman who experiences any of these symptoms should contact her gynecologist immediately for evaluation.
