Which of the following is NOT a common symptom of a UTI?

Excessive thirst is not a common symptom of a urinary tract infection (UTI). Typically, UTIs are characterized by symptoms that directly relate to the urinary system and the bladder's irritation or infection. Common symptoms include a burning sensation during urination, which is a direct result of inflammation in the urinary tract. Cloudy urine is often observed due to the presence of bacteria, pus, and other components that can cause turbidity. Lower abdominal pain is also associated with bladder irritation and potentially with inflammation of the surrounding tissues.

In contrast, excessive thirst may suggest other medical issues, such as diabetes or dehydration, rather than directly indicating a UTI. Therefore, it does not fit within the typical symptomatology associated with urinary tract infections.
