Not only high levels of sugar in the blood may result into hyperglycemia. It’s about critical types of illnesses such as serious problems with heart because of the survived stressful situations. Some people cannot withstand the amount of stress on their shoulder. It may be caused by the work overload or studies; some patients get sick if they face a life-dangerous situation. Any great shock may provoke hyperglycemia as well as further diabetes progress. Watch out if you know what stroke or myocardial infarction is based on personal experience. When combined, these factors may end up fatally; instead of diabetes, the person may die from the stress-induced hyperglycemia.
