Hello dr, Greetings! My mother is aged 56. She is a TYPE 2 diabetic and her Fasting used to be 300 and Post fasting was 375. she was on Insulin , Pioglitazone 15mg and Metformin 500. Recently she has stopped insulin and tablets and had diet control and exercise now her blood sugar level has come down to Post fasting 275(after 2 hours of food intake), She achieved these without the help of any tablets or Insulin I would like to know whether she should start taking Insulins or Pios and Metformin. Or shall she continue at this rate or whether she should reduce the amount?
