My physician has ran many test trying to explain why my sugars will not go below 200. My liver,etc is fine. She did not detect any infections. She increase my once a day metformin(was winging me to get off for my sugars was normal until the third week in October) to 2000mg a day and two glipizide 10mg. I can not work out for my blood sugars will skyrocket from 280 or in the 200 s to 400 s. I haven t worked out in three weeks. I am always tired. I feel old! I was diagnoised with diabetes type 2 last summer when I was told that an infection attacked my pancreas. I have hypothyroid. I am 5 10, reduced my weight from 223 to 176. I have been dropping weight the last month without trying. I realize that I have not gottent my teeth clean. Do you think that an infection in my mouth or cavity cause my blood sugars to go up?
