Prehabilitation: metabolic considerations

Purpose of review The major components of ERAS attenuate the inflammatory response and modulate metabolism in direction of sparing body protein and preserving function. However, these perioperative interventions might have limited effectiveness on postoperative outcomes if preoperative risk factors are not addressed and optimized. Recent findings The preoperative metabolic perturbations characterized by insulin resistance and sarcopenia might predispose patients to a higher degree of postoperative catabolism. High-risk populations for such metabolic disturbances include elderly and frail patients, and patients with metabolic syndrome. Research on the effect of prehabilitation on perioperative metabolism is limited, but recent findings suggest that interventions designed to improve insulin sensitivity prior to surgery might represent a promising therapeutic target to minimize surgical complications. Summary The present paper will discuss the metabolic implications of modulating preoperative risk factors with elements of multimodal prehabilitation, such as exercise training and nutrition.
