Hello, Since you have history of diabetes and now you are experiencing excessive sweating, it commonly occurs when blood glucose drops too low, you produce excess adrenaline, which causes sweating. The sweating should stop when the blood glucose returns to normal. If obese, control your weight. You should do regular exercises and walking to maintain healthy weight. Other medical conditions that may cause excessive sweating are hyperhidrosis, thyroid problems, hypertension or may be a warning sign of developing CAD. You are suggested to get a total health check up done with investigations to detect any thyroid problem, hypertension or cardiac problems developing so that you can be treated at the earliest. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
