What causes a bladder infection?
Bladder infections are most often caused by bacteria. Rarely, fungi and viruses may cause a bladder infection in children.
Normally, the body keeps bacteria in the urinary tract in balance. Emptying the bladder, or urinating, is one way the body helps keep a healthy number of bacteria in the bladder. Emptying the bladder also helps get rid of any bacteria that may cause a urinary tract infection (UTI).
