Having diabetes for nearly 50 years I can say this about diabetic comas. I diabetic coma can happen for having too high a blood sugar which would require insulin. Or it could be from having too low a blood sugar which would respond to orange juice ( or some other form of carbohydrate or sugar). They are both dangerous situations that must be treated. But they are opposite ends of the spectrum and wouldn’t happen at the same time. The trick is monitoring blood sugar, finding the healthy targeted blood sugar range and the appropriate treatment to stay in that range.
