Abstract
We analyzed 137 episodes of hypoglycemia (serum glucose ≤49 mg per deciliter) occurring in 94 adult patients hospitalized during a six-month period at a tertiary care hospital. Forty-five percent of the patients had diabetes mellitus, and administered insulin was implicated in 90 percent of episodes in diabetics. Hypoglycemia in diabetic patients occurred under a variety of circumstances, frequently because of decreased caloric intake related to illness or hospital routine. Insulin-induced hypoglycemia also occurred during treatment of hyperkalemia (eight patients) or during hyperglycemia related to total parenteral nutrition (six patients).
