I am a 69 years old lady diagnosed with diabetes for the last 25 years. I have controlled my diet for the last 11 years and had some oral medication for about 5 years or so. But my cardiologist found that my kidneys’ functioning was compromised because of metformin, I was put on. Then he suggested insulin and asked me to stop metformin. Now I am taking 2 long acting and 3 rapid acting injections every day. Now, I gained a weight of 20lbs. For the last 2 years, my kidney is functioning well. Now, my diabetes care doctor wishes to make me go back to metformin and byetta. What will you suggest?
