Symptoms of low blood sugar include cold sweat, blurred vision, dizziness, drowsiness, shaking, fast heartbeat, headache, fainting, tingling of the hands/feet, and hunger. Do not use table sugar (also called cane sugar or sucrose) to relieve these symptoms because acarbose delays its breakdown. Carry glucose tablets or gel with you to treat low blood sugar.
