Which of the following symptoms indicates a higher likelihood of a urinary tract infection?

The symptoms of frequency and urgency are strongly associated with urinary tract infections (UTIs). These symptoms arise due to irritation and inflammation of the bladder and urethra, which is common when bacteria infect these areas. Individuals experiencing a UTI often feel the need to urinate frequently and have a strong, sometimes painful urge to urinate, even if only small amounts of urine are produced. This characteristic symptomatology is crucial for identifying the presence of a UTI, making it the most indicative choice among the options presented.

Increased thirst and dry mouth can sometimes occur during a UTI, but they are not specific symptoms and can relate to many other conditions, such as diabetes or dehydration. Fatigue is a nonspecific symptom that can result from various medical issues and does not correlate directly with UTIs. Therefore, while these other symptoms may occur, frequency and urgency are the hallmark signs that indicate a higher likelihood of a urinary tract infection.
