Bladder Infection (interstitial cystitis) is the chronic Inflammation of the urinary bladder. Cystitis occurs much more frequently in women than men because the urethra in females is about one-seventh as long as it is in males. Microorganisms, which normally exist only in the external opening of the urinary tract, pass through the bladder - causing fungal, viral or bacterial Infection.
Migration of bacteria, especially Escherichia coli (E. coli) that normally live in the intestines, is also facilitated in women because the openings of the female urethra, anus and vagina are in close proximity.
