Sweating in diabetes may be caused by physiological factors, or it may be caused by hypoglycemia, diabetic neuropathy and other diseases. 1. Physiological factors: sweating can be caused by hot weather, heavy exercise, etc. It is a normal physiological phenomenon. 2. Hypoglycemia: Sympathetic nerve excitation during hypoglycemic episodes can lead to sweating symptoms, accompanied by hunger, fatigue, dizziness, panic and other symptoms, and even coma in severe cases. 3. Diabetic autonomic neuropathy: When autonomic neuropathy occurs, the normal sweat secretion function may be damaged, leading to abnormal sweating and symptoms such as sweating, no sweating and little sweating. Diabetic patients with abnormal sweating symptoms are advised to go to the hospital.
