What is a common symptom of a urinary tract infection?

Frequent urination is indeed a common symptom of a urinary tract infection (UTI). When the bladder becomes inflamed and irritated due to the infection, the body often responds by signaling the need to urinate more frequently. This urgency occurs because the infection can cause the bladder to respond as if it is full, even when it is not. Individuals may find themselves needing to urinate more often, and this can be accompanied by a sense of urgency and discomfort.

Additionally, other symptoms associated with UTIs often include pain or a burning sensation during urination, cloudy or strong-smelling urine, and possibly pelvic pain. The combination of these symptoms can help distinguish a UTI from other health issues.

In contrast, the other options do not typically present as direct symptoms of a urinary tract infection. Improved appetite is generally not associated with UTIs, as the illness often leads to discomfort and possible changes in nutrition and hydration habits. Weight gain is not a symptom linked to UTIs; in fact, the condition tends to have the opposite effect due to discomfort and potential loss of appetite. Lower back pain can occur, particularly if the infection has ascended to the kidneys, but it is not as universally recognized as a primary symptom of a urinary tract infection
