Dear doctor, In february 2010. I had fasting glucose plasma level of 6.89 mM/L, and today (Sept. 2010) it was 8.21 mM/L. I am 47, obese (170 cm and 113 kg) and I take clozapine for a number of years (50 mg at the bedtime). Today, my physician introduced me metformin (500 mg twice a day). Last year I started to take drugs for arterial hypertension, now I take ramipril and amlodipine. I wonder do I already have diabetes mellitus type 2, or it has to be confirmed with one more blood test showing fasting glucose over 7.0 mM/L in plasma. Anyway, even if I have diabetes, since it is an early stage, could it be overcome providing I lose at least 30 kg and practicing exercise. Can I be healthy enough again to regulate blood sugar without taking oral antidiabetics? So, could I be healthy again - without diabetes, or even though this may an early stage of diabetes it will never reverse to a healthy stage? Ninoslav
