My husband has had a perfect A1c for the last 5 or 6 years. He is not on a special diet or an exercise routine. He pretty much eats what he wants. Well his doctor has recently increased one of his blood pressure medications (Coreg) and he is now having issues with high blood sugar. Extra weight and added stress could also be factors, but because this seems to have happened quite literally overnight, I want to blame it on the medication. I haven’t found anything linking Coreg to high blood sugar and because of this, my husband doesn’t think it is the medicine. I am still holding out that it is. Has anyone had any like experience with this particular medication?
