Post-bariatric nutritional care is essential to ensure long-term health and successful weight management after bariatric surgery. These procedures alter the digestive system, often reducing nutrient absorption and affecting food intake. Patients require a specialized diet, emphasizing high-protein, low-sugar foods, to maintain muscle mass and meet nutritional needs. Regular intake of supplements, including vitamins B12, D, calcium, and iron, is typically necessary to prevent deficiencies. Dietary changes must also address smaller portion sizes and slower eating. Monitoring by healthcare professionals ensures adherence to nutritional guidelines, promotes weight maintenance, and prevents potential complications. Comprehensive post-surgery nutritional care helps maximize the benefits of bariatric procedures for sustained weight loss and health improvement.
