A urinary tract infection (UTI) is an infection that can affect any part of the urinary system, including the kidneys, ureters, bladder, and urethra. The most common type of UTI is a bladder infection, known as cystitis, which can cause uncomfortable symptoms such as a frequent urge to urinate, a burning sensation during urination, and cloudy or strong-smelling urine. In more severe cases, a UTI can ascend to the kidneys, potentially leading to more serious complications. While UTIs can occur in anyone, they are particularly prevalent among women due to anatomical differences that make it easier for bacteria to reach the bladder.
The main cause of UTIs is the introduction of bacteria, often from the digestive tract, into the urethra. Risk factors may include sexual activity, certain types of birth control, and urinary retention. Treatment typically involves antibiotics, and in many cases, symptoms may begin to resolve within a few days of starting the medication. Staying well-hydrated, wiping front to back after using the restroom, and urinating after intercourse are some preventive measures to help reduce the risk of developing a UTI.
