what causes uti

A urinary tract infection (UTI) is typically caused by bacteria entering the urinary tract through the urethra and spreading to the bladder. The most common cause of UTIs is Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal tract. In women, the urethra is close to the anus, making it easier for bacteria to enter the urinary tract. Other risk factors for UTIs include sexual activity, changes in the bacteria that live inside the vagina, pregnancy, and structural problems in the urinary tract, such as an enlarged prostate. UTIs can be treated with antibiotics, and symptoms may include pain or burning while urinating, frequent urination, and a strong urge to urinate. In some cases, UTIs can lead to more serious complications if left untreated, such as kidney infections
