Problems that may arise

Sometimes your blood glucose may become high even when you are feeling well and taking good care of yourself. When that happens and ketones are present, you may become very sick with an illness called "DKA," or "diabetic ketoacidosis." Your blood glucose may also become too low, in which case you may have an insulin reaction.
