Abstract:
Gastric bypass surgery may be the most successful treatment for morbid obesity. However, postoperative patients are susceptible to deficiencies of several nutrients, including iron, vitamin B(12), and folate. Careful monitoring and supplementation are recommended to prevent negative outcomes of nutrient deficiencies. Metabolic benefits, on the other hand, include improvements in glycemic control and biochemical risk factors for cardiovascular disease. Pursuing surgery as an option for treating morbid obesity requires long-term dedication from the patient and the healthcare team.
