Comprehensive Nutritional Optimization for Patients Recovering from Surgery

Substantial Skeletal Muscle Loss Occurs After Surgery with The most muscle atrophy is seen during the initial 2 weeks post-op.

Decreased mobilization leads to further muscle atrophy:
0.5% /day in young 1.0% /day in elderly

This catabolic state requires elevated (~80%) demands for essential amino acids [EAA].

EAAs serve as the necessary building blocks for collagen, bone and Muscle Protein Synthesis (MPS).

Without adequate nutritional support, the body harvests its only reserve (skeletal muscle) to provide these critical substrates for tissue healing.
