After undergoing Roux-en-Y gastric bypass surgery (RNY), the diet is critical for long-term success and recovery. Immediately after surgery, patients are required to follow a liquid diet to allow their stomachs to heal. Over time, they transition from liquids to soft foods, and eventually solid foods. This post-op diet is high in protein to support muscle retention and healing, low in fats and sugars, and carefully portioned to avoid stretching the stomach pouch. Lifelong dietary changes are necessary to avoid nutritional deficiencies, with a focus on vitamin supplementation, hydration, and balanced meals.
