Hospital patients adhering to structured exercise and nutrition support before undergoing surgery can reduce their overall complications and shorten their hospital stay, according to findings from a new scientific review. Post-surgery complications after surgery, such as infections and wound-healing issues, can prolong hospital stays, increase health care costs, and delay or prevent patients from returning to work and to their daily lives. Prehabilitation programs are designed to help patients optimize their health before surgery, promoting faster, better recovery.
