A urinary tract infection (UTI) is an infection that occurs in any part of the urinary system, which includes the bladder, urethra, ureters, and kidneys. UTIs are most commonly caused by bacteria entering the urinary tract, leading to symptoms such as a frequent urge to urinate, burning sensation during urination, and cloudy or strong-smelling urine. While UTIs can affect anyone, they are more common in women due to their shorter urethra. Treatment typically involves antibiotics to eliminate the infection. Drinking plenty of fluids and practicing good hygiene can help prevent UTIs from occurring.
