Mr. Lybrate-user, your blood glucose level is high particularly pp. But this can be corrected by diet and exercise rather than any new drug addition, if you reduce present intake by about 10 to 15%, consume more of green leafy vegetable and fiber containing product, plus exercise regularly then you can bring down the sugar level closer to the target of fasting 100mg and pp <170 mg.

Hi ..your blood sugars levels looks quite controlled as per your levels mentioned .
but still i would suggest you to get
HBA1C , TSH

You have to get yourself worked up for weight loss .

coz 14 kg is quite significant

Matter is what is required and giving you good result that is your medicine. Of course that should not cause damage to your health - your consultant definitely knows that. Trust him.
