Welcome to HCM
Your case is good example why we should have medical checkup even without any complaints as many times diabetes
Initially your blood sugar level was very high hence insulin
was given ,now follow diabetic diet and regular waliking exercise 3 to 4 km every day as your age is onlt 36 years. I hope other test like Lipid profile
and kidney functions are OK and you are not having high BP.
What about your family history of Diabetes?
Your medicine of diabetes is all right, only thing check your blood sugar intermitantly and also check HBA1c every 3 monthly to know status of control of blood sugar.
Please continue to take medicine and if you are overweight
reduce weight, and if you smoke please quit .
By chance if you take alcohol stop it completely if not at least moderate the use.
Good Luck to you
