To the editor: Medical professionals are taught that stress (in this instance, emotional) raises blood sugar levels in diabetics. I have seen multiple diabetics (I and II) in multiple facilities have high readings at times of stress that are seemingly “unexplainable.” Someone I know well has been fighting to get their AIC down for years, but it stubbornly stays high. I can attest to the efforts this individual has made in watching diet, checking frequently, etc. Recently I bought this individual a second glucose meter; this individual since checked with both meters side by side. Sure enough, both meters (the two-year-old one and the brand-new one, both machines from different brands) sometimes were near identical (say 121 and 123 certainly close enough), but just as often sometime wildly apart (say 152 and 247).
