If the amount of urine increases, the first thing to consider is the possibility of diabetes. In this case, a routine urine test will reveal a significant increase in urinary glucose. If a blood test for blood glucose is performed, an increase in blood glucose will also be found. For this situation, it is necessary to go to the hospital's endocrinology department for hypoglycemic treatment in a timely manner. Secondly, diabetes insipidus should be considered, which also causes an increase in urine volume, and the patient will have obvious thirst. Routine urine tests find that blood sugar in the urine is not high, the specific gravity of urine will initially decrease, and the patient's daily urine output will exceed 2500 milliliters, even reaching more than 4000 milliliters.
