On the other end of the spectrum, urinating only once or twice a day — or producing very small amounts overall — may suggest dehydration or underlying urinary tract issues and should not be ignored.
Medical attention is recommended if urination becomes painful, burning, or difficult, or if there is discomfort in the lower back or pelvic area. Blood in the urine, loss of bladder control, or unusually cloudy or foul-smelling urine are also warning signs.
Doctors typically use a combination of tests to determine the cause of abnormal urinary patterns, including urinalysis, kidney function tests, imaging scans, and uroflowmetry, a non-invasive assessment of bladder performance that helps evaluate flow and emptying issues.
