Interstitial CystitisInterstitial cystitis is an inflammation of the bladder that affects women 10 times more often than men. It causes a woman to need to go to the bathroom often -- as often as 30 times a day or 20 times a night.
Besides the urgent need to go to the bathroom often, insterstitial cystitis causes pain in the lower abdomen.
Doctors are not certain what causes interstitial cystitis. It could be a virus, an autoimmune disease or a defect in the lining of the bladder.
