Hypoglycemia is a complication of the "tight control" method of controlling hyperglycemia. Older adults experience hypoglycemia more quickly than do younger people, and the elderly are more prone to hypoglycemic episodes. The older adult may progress to dangerously low levels of blood glucose before signs and symptoms are obvious. Severe hypoglycemia in the older adult can precipitate myocardial infarction, angina, stroke, or seizures. For this reason, "tight control" may not be the best thing for the older adult.
