Hi all, I recently started insulin therapy for type 2 and currently being titrated two units every four days up to 26 units of mixed twice daily, my numbers have been coming down very nicely and although still getting over 10 mmols diabetic nurse is pleased not due to raise another two until next weds, however I had surgery under local anaesthetic two days ago and I have noticed my blood glucose levels have risen despite taking an extra two units of insulin since the day before surgery, should i be concerned or is this usual? or can you become more resistant to insulin like a plateau effect?
