My mom is diabetic for the past 15 years and she is 55 yrs old now. Recently she has kidney infection "sepsis" and had operation recently. She was told to take insulin for the first time during her recovery days of 2 months. Her sugar levels were 120 before food and 200 after food ( along with insulin). Later her sugar levels reduced to 108/160. She now stopped insulin and was prescribed istamet 50/500mg (plus glimy1 before food) for the first time. She has severe side effects now and has now become more tired and weak. She has severe loose motions, lose of appetite , no taste for food, pain in the kidney where it was operated , stomach pain , severe tiredness etc . Could some doctor kindly help us understand what's going on?
