Hi, After going through your case details, I want to know- 1) Your Age. 2) Your Height and weight (It very encouraging that you have lost significant weight with diet and exercise) to evaluate degree of overweight. 3) Family history of obesity, diabetes. 4) Current medicines other than Glycomet (metformin) if any. 5) Any associated high blood pressure or cholesterol problem. You should not worry about single BSL reading of 185. I would like to advise you - 1) Continue Low calorie diet and regular exercise. 2) Quarterly check your HbA1c level that give much better idea regarding your diabetes control. Also check Blood sugar level Fasting and postprandial once in a month or two months. 3) If it is feasible for you to do Self monitoring of blood sugar level (BSL done by glucometer at different times of the day (Fasting, 2 hours after breakfast, before lunch, 2 hours after lunch, before dinner, 2 hours after dinner, early morning sugar 3am) all sugar not daily but whole profile in a week at least once in a month. If there are symptoms of low BSL or High BSL you should confirm it. 5) Regular BP check, clinical examination to rule out microvascular complications of diabetes (retinopathy - fundiscopy, foot examination for neuropathy) 6) Check your Lipid profile, it is advisable to take statin (lipid lowering drugs) in diabetes patients above 35yrs though normal lipid level. 7) It better for you to take metformin in maximal tolerated dose, as it will help in reducing insulin resistance which is a basic pathology of diabetes. Metformin is weight neutral (may help in decreasing weight) and rarely causes hypoglycemia. 8) Depending upon your BSL control and HbA1c level other antidiabetic medicines can be added.
