Welcome to HCM
You are newly detected diabetic,I hope and you was treated with insulin and your blood sugar level is brought to the euglycemic level,now you are taking triple drug that is metformin
,Glimiperide and pioglitazone
, as you are taking with lunch and dinner it is quite possible to have hypoglycemia
These drugs are long acting drugs.
You certainly need dose adjustment for which you should consult your Physician/Endocrinologist
,who may reduce the dose accordingly.
Initially higher dose of insulin and oral drugs may be high but once blood sugar level is controlled the required dose of oral hypoglycemic drug may come down.
You should also take care of diet and exercise regularly specially if you are overweight
Take care of your health
