| Management | Stress reduction, shortterm glucoselowering steps | Medications, longterm lifestyle changes |

Anyone can develop stress hyperglycemiastudents pulling allnighters, busy parents, even pregnant women. Its especially common in nondiabetics who experience chronic cortisol spikes.
RealWorld Anecdote
