What could be causing my frequent urination?

Dr. William Sullivan


Frequent urination is a common symptom when blood glucose levels are excessively elevated (usually over 200-250 mg%). Although excessive urination can occur with elevated blood glucose, many patients with diabetes can have elevated blood glucose without this symptom. There are other causes of frequent urination that include a bladder infection (frequent urination, often with burning with urination) or excessive fluid intake. A rare cause of excessive urination is diabetes insipidus (caused by a deficiency of one of the pituitary hormones). If you are having frequent urination, it is important to have an evaluation by your healthcare provider to determine the cause. If frequent urination is related to high glucose levels, adjustments in diet/exercise or medications will alleviate this symptom.
