Gestational diabetic mellitus (GDM) patients randomised to metformin or insulin group.Aim was to achieve blood sugar levels of Blood sugar fasting (BSF) <5.3 mmol/l and 1 hour post meal<7.8mmol/l. Both groups were followed till delivery and outcome studied.

75 gm Oral Glucose Tolerance Test (OGTT) was done in pregnant patients. Blood sugar fasting(BSF) > 5.5 mmol/l & 2 hours postprandial >7.8 mmol/l was labelled as GDM. They were randomised to metformin or insulin group. Those assigned to metformin group were started metformin 500mg twice daily & increased until 2500mg depending on the blood sugar levels. Aim was to achieve blood sugar levels of BSF <5.3 mmol/l and 1 hour post meal<7.8mmol/l. If blood sugar levels were not controlled, insulin was added. The insulin group was given 3 injections of regular insulin & one intermediate acting insulin injection at night subcutaneously. Both groups were followed till delivery and outcome studied
