Evaluation of death from hypoglycemia.

Hypoglycemia involving a serum glucose of 40 mg/dl or less may lead to death from hypoglycemic coma. Hypoglycemia may be a factor in sudden or unexpected deaths investigated by a medical examiner. We reviewed the data from 54,850 autopsies in a large acute-care medical center to investigate the range of underlying conditions leading to hypoglycemic coma and found 123 cases, which included complications of alcoholism in 41 (33%), drugs in 26 (21%), neoplasia in 26 (21%), conditions producing chronic passive congestion of liver in eight (7%), debilitating neurologic disease in eight (7%), endocrine disorders in four (3%), and a variety of miscellaneous conditions in ten (8%) cases. The commonest mechanisms producing hypoglycemia included liver disease with impaired carbohydrate metabolism, endogenous or exogenous drug or hormonal effect, and inanition from decreased intake of food.
