Gastric bypass procedures are the most effective weight loss surgical treatments.1 The Roux-en-Y procedure, the most commonly performed bypass technique in the United States, restricts gastric volume and bypasses absorption from most of the proximal small intestine. Bypass of the duodenum impairs mixing of ingested nutrients with bile acids and pancreatic enzymes leading to maldigestion. The combination of malabsorption and maldigestion, while resulting in significant weight loss, predisposes to malnutrition.
