Nutrition is important for surgical recovery, and it affects wound healing, immunity, and patient outcomes. Perioperative nutrition assessment reveals patients with malnutrition risk so that specific interventions like immunonutrition, protein supplementation, and preoperative carbohydrate loading can be offered. Inclusion of nutrition within ERAS programs enhances postoperative recovery, decreases complications, and reduces hospital stay. Multidisciplinary collaboration among surgeons, dietitians, and anesthesiologists ensures proper implementation of nutritional strategies, improving patient resilience and success of the surgery.
