I am 54 years and diabetic since last 3 months. I take 2 glycomet 250mg, one in the morning and one in the night. I tested my blood sugar afew days ago and fasting is 117 and pp is 127. Glycosylated sugar reading is 6.8 and mean blood glucose is165mg/dl. I feel that this average blood glucose is very high under medication. I walk twice a day for 40 minutes each time. Please could you advice me if dosage needs to be increased?
