Hypoglycemia (abnormally low blood glucose level) occurs whenthe blood glucose falls to less than 50 to 60 mg/dL (2.7 to 3.3 mmol/L). It can be caused by too much insulin or oral hypo-glycemic agents, too little food, or excessive physical activity. Hy-poglycemia may occur at any time of the day or night. It oftenoccurs before meals, especially if meals are delayed or snacks are omitted. For example, midmorning hypoglycemia may occur when the morning regular insulin is peaking, whereas hypo-glycemia that occurs in the late afternoon coincides with the peak of the morning NPH or Lente insulin. Middle-of-the-night hypo-glycemia may occur because of peaking evening or predinner
NPH or Lente insulins, especially in patients who have not eaten a bedtime snack.
