 While the mechanism leading to blunted counterregulation is unknown several have been proposed.It has been frequently found that those type 1 diabetics found "dead in bed" in the morning after suspected severe hypoglycemia had some underlying coronary pathology that led to an induced fatal heart attack.In 2010, a case report was published demonstrating the first known case of an individual found "dead in bed" whilst wearing a continuous glucose monitor (CGM), which provided a history of glucose levels before the fatal event; the person had suffered a severe hypoglycemic incident, and while the authors described only a "minimal counter-regulatory response" they stated no "anatomic abnormalities" were observed during autopsy.
