### output:

Hello, Thank you for your query. I understand your concerns. For ideal control of blood glucose your fasting blood glucose should be less than 110 mg/DL and your 2-hour post radial should be less than 160-170 mg/DL. Your random blood glucose should also be less than 170 mg/DL. Seen this way, your blood glucose reading seems alright to me, as I feel both of the tests that you have taken are random. The morning blood glucose is still at the borderline, but your evening blood glucose is quite normal. If you could start exercising, you blood glucose values would come even lower than this. Is there any reason that you are not exercising like arthritis of knees etc.? If you want you could increase your night dose of Metformin to 1000 mg and continue with your morning dose of Metformin 800 mg and recheck your blood tests in a couple of weeks. If your morning blood glucose test reading is too low (like 60-70 mg/DL), you could go back to the 800 mg at nighttime. If you are going to start exercising, then you can continue the same dose of Metformin 800 mg twice a day, as exercise increases insulin sensitivity. I hope this answer has been helpful to you.
