Hi welcome to HCM.You have not mentioned your wife's age and body weight and whether the level is fasting or post meal. Bigomet or metformin
is the best starting medicine for a diabetic who is of normal weight or obese but not if she is thin. Metformin brings down body weight, reduces appetite, and corrects metabolic syndrome(insulin resistance
, high BP, high triglycerides, overweight
) that is the cause of diabetes in Type -2 cases. However it does lead to gastric irritation, B-12 deficiency and magnesium deficiency
. Hope this answers your query. Best wishes.
