Commonly abbreviated as UTI, a urinary tract infection is a localized infection that affects the bladder, kidneys or another part of the urinary tract. The infection often causes pain and discomfort, and treatment typically involves a course of antibiotics. Women are generally much more susceptible to urinary tract infections than men, but UTIs are relatively common in both sexes.

To avoid infections, a person can maintain a healthy diet, urinate 15-20 minutes after intercourse, avoid unprotected sex, and use appropriately pH-balanced lubricants.
