A Urinary Tract Infection (UTI) is a common medical condition that occurs when bacteria or other microbes enter and infect any part of the urinary system, which includes the kidneys, bladder, ureters, and urethra. UTIs can affect people of all ages and genders, but they are more common in women due to the shorter length of the female urethra, which makes it easier for bacteria to reach the bladder. UTIs vary in severity, and if left untreated, they can lead to more severe complications.
