my husband has had elevated blood sugar of 361. Since Sunday, we ve managed to get it down to 161 with diet, exercise and additional 1000 mg of metformin, an increase from 1,000 mg to 2,000 mg daily. He has had diarrhea since last night, however. Water like. should we be concerned. We are out of town and cannot reach his doctor who is also out of town until Thursday. Other than the diarrhea, he is feeling ok. No nausea, etc. He is hurting on his lower right side too.
