Diabetes mellitus often has no obvious symptoms at the beginning, but some patients may have “three more and one less” symptoms. The symptoms of urination are mainly frequent urination and increased nocturia in men. The increase in nocturnal urination is due to the abnormal glucose metabolism in diabetes, which leads to an increase in blood glucose and then urine glucose, and the osmotic diuresis of urine glucose, so the patient will experience an increase in nocturnal urination, and some patients may have as many as several times at night.
