    What causes Urinary Tract Infections ?
    ### Response:
    Most urinary tract infections, or UTIs, are caused by bacteria that enter the urethra and then the bladder. A type of bacteria that normally lives in the bowel (called E. coli) causes most UTIs. UTIs can also be caused by fungus (another type of germ). Who Gets UTIs? Although everyone has some risk for UTIs, some people are more likely to get UTIs than others.
