It is suggested that elderly people mount an inadequate response to the insulin resistance of critical illness, which is produced by the actions of increased counterregulatory hormones and cytokines (McCowen et al., 2001).
Together with their extrahepatic actions, the counterregulatory hormones tend to increase the blood glucose level, while the actions of insulin on the liver and other tissues are hypoglycaemic.
Moreover, algorithms linking the sensor with the delivery system must also account for all the other physiologic factors that contribute to glucose homeostasis, such as incretins, free fatty acids, and counterregulatory hormones.
Anaerobic exercise, such as sprinting, involves the release of counterregulatory hormones (cortisol and epinephrine) that can sharply increase glucose release from the liver.
