A urinary tract infection (UTI) is an infection that can occur in any part of the urinary system, which includes the kidneys, bladder, ureters (tubes that connect the kidneys to the bladder), and the urethra (the tube through which urine exits the body). UTIs are more common in women than in men, and they can range in severity from mild to severe.
The majority of UTIs are caused by bacteria, most commonly Escherichia coli (E. coli), which normally inhabit the colon. UTIs can also be caused by other bacteria, viruses, or fungi.
Treatment for UTIs usually involves a course of antibiotics to eliminate the infectious bacteria. The specific antibiotic prescribed may vary based on the type of bacteria causing the infection and its sensitivity to different antibiotics.Pain relievers may be recommended to alleviate discomfort, and in some cases, urinary tract analgesics may be prescribed to ease symptoms during urination.
