My dad had a colonoscopy today. He became nauseous and vomited after the procedure. Came home, rested. Ate some soup, drank fluids, and rested most of the day. He ate a little more soup and drank fluids. He became I'll again late this evening, and has a headache. He also earlier took tyelenol. His procedure was at 10:30 and it is now 9:00. He is also type two diabetic, he took his blood sugar and its 153. Not too low, maybe elevated. What should he do?
