Teaching Visit: (Week -2 or prior to week -1): A research nurse will give diabetic subjects a 30-minute refresher course on diabetes that will include the signs and symptoms of hyper and hypoglycemia. A teaching booklet will be given to each diabetic subject. Some type 2 diabetic (T2DM) patients only on oral medication do not regularly check their blood sugar. If the patient does not have a glucometer, we will provide a glucometer, supplies and instructions for use by our diabetic study volunteers during their study participation.
