Final answer:
Roux-En-Y gastric bypass surgery creates a small stomach pouch and reroutes the small intestine to help with weight loss by limiting food intake and nutrient absorption. Gastric sleeve and gastric banding surgeries are other bariatric procedures that alter stomach size but differ in terms of nutrient absorption.
Step-by-step explanation:
The name of the procedure that allows better movement of the stomach contents into the duodenum is called Roux-En-Y gastric bypass surgery. In this bariatric surgery, a small pouch is created at the top of the stomach, and the small intestine is rerouted to this pouch. The majority of the stomach and the first portion of the small intestine (the duodenum) are bypassed. This change not only reduces the size of the stomach and limits food intake but also impacts the absorption of nutrients, which contributes to weight loss.
Patients who qualify for bariatric surgery are typically those for whom diet, exercise, and medications have not been effective in treating obesity. The common types of bariatric surgery include gastric bypass, gastric sleeve, and gastric banding. Each type modifies the stomach differently. Gastric bypass is highly effective because it restricts both food intake and nutrient absorption. Gastric sleeve surgery involves the removal of a portion of the stomach, forming a 'sleeve' or tube, which also reduces food intake but doesn't affect nutrient absorption as much. Gastric banding involves placing an adjustable band around the upper portion of the stomach to create a small pouch, thereby restricting food intake but not nutrient absorption.
