I am 40 years old, and my weight is 97 kilograms. I am a diabetic patient, and my A1C test showed a result of 9 %. I am taking Sitaglu Met 500 mg. It has not helped me. When I take it, within five minutes, my sugar level gets increased to 250 mg/dL and comes down again to 180 mg/dL or 190 mg/dL. Sometimes, it does not get reduced. My fasting blood sugar level is 180 mg/dL. I am thinking to change my medicines. Please suggest.
