Just out of curiosity, where did you read that lipitor can raise blood sugar in some individuals? I have only run across reports that it does not impact control of blood sugar level at all.
Based on those reports, the physician is correct, if the fasting glucose level is >127 mg/dL, he is diabetic and needs to initiate some action. He could request to be off lipitor and have another fasting blood sugar, but based on what I have read and keeping all other factors the same, I would not expect the faster sugars to come back putting him in the non-diabetic range.
Having said that, if someone can provide me with a reference where lipitor has been shown to increase or impact glucose levels, I would appreciate it.
