Ivan, I'm concerned that you might have hypoglycemia unrelated to PD and pray that your doctor will be more aggressive in diagnosing the culprit. At any rate, using any urine glucose test is irrelevant in your case since those tests are constructed to identify high glucose levels - your problem exists in the opposite direction. Please, please.....insist on taking a glucose tolerance test. If you have severe hypoglycemia your life might depend upon it. At the very least, you should be on a diabetic diet in an effort to avoid hypoglycemic attacks. Once again, I encourage you to have peanut butter or cheese on hand when these attacks occur. Taking juices or candy will only exacerbate the problem if you have true hypoglycemia. ----- God bless Mary Ann
