Hypoglycemia during, and following exercise is frequent in people with type 1 diabetes. The increased risk and impaired awareness that can result from exercise-induced nocturnal hypoglycemia are important clinical problems. Varying intensities, durations and forms of exercise produce different patterns of endocrine and glycemic responses, which influence the risk of exercise-related hypoglycemia. Recent clinical studies have characterized the underlying physiology of the glycemic response to exercise, and offer strategies to reduce the risk of exercise-related hypoglycemia. Advances in insulin infusion pump therapy and continuous glucose monitoring are useful adjuncts to the management of people with type 1 diabetes who wish to exercise.
