Postabsorptive period blood glucose

EXAMPLE 13.2 It is important to distinguish between a nondangerous decrease in blood glucose concentration that stimulates a metabolic response and an overtly hypoglycemic episode. During the postabsorptive period, blood glucose concentration falls to 4 mM, and this is sufficient to stimulate the appropriate hormonal responses that, in turn, stimulate the mobilization of glycogen stores.
