Weight Loss Surgery Options
Duodenal switch surgery is a weight-loss procedure that combines the principles of restriction and malabsorption by making the stomach smaller and rerouting the intestines. This combination of treatments is a proven, effective way to lose weight and improve weight-related health issues.
What is duodenal switch surgery?
Biliopancreatic diversion with duodenal switch (BPD-DS) surgery is a 2-part procedure in which approximately 75-80% of the stomach is removed (similar to the gastric sleeve surgery). Then, a small, tubular stomach pouch is created. The outlet of the newly created stomach pouch is then connected to the last portion of the small intestine called the duodenum.
How does duodenal switch surgery work?
Food empties directly into the duodenum, bypassing about ¾ of the small intestine. This causes the body to absorb fewer calories and nutrients. Duodenal switch surgery affects hormones in the gut to reduce hunger, increase satiety (satisfied feeling of being full after eating) and help control blood sugar to effectively treat diabetes.
What are the benefits of duodenal switch surgery?
Duodenal switch surgery provides the highest average expected weight loss available among bariatric procedures and offers the best chance of curing diabetes (up to 98%).
After surgery, the stomach is roughly the size and shape of a banana and can hold approximately 3 ounces of food, as compared to the average stomach which can hold up to 4 cups of volume. Additionally, by shortening the path food travels through in your intestine you absorb fewer calories. This combination of restriction and malabsorption creates a rapid weight loss. BPD-DS will not eliminate your desire for food completely, but many people eat because it is time not because they feel hungry.
About Gastric Bypass Surgery
In gastric bypass surgery, a small stomach pouch is created by dividing the top of the stomach from the rest of the stomach. The first portion of the small intestine is divided and connected to the newly created stomach pouch. The other portion of the divided small intestine is then connected further down the small intestine so the stomach’s acids and digestive enzymes in the bypassed stomach will still be able to react with food. This surgery limits the amount of food you can consume before feeling full. Most patients see up to 80% excess weight loss within 18 months.
Changes in gut hormones are a result of the rerouting of the food stream. These hormones help make you feel fuller, suppress hunger and reverse one of the primary mechanisms that causes type 2 diabetes.

About Sleeve Gastrectomy
Gastric sleeve surgery involves surgery on the stomach only (considered a “restrictive” procedure). A thin vertical sleeve of stomach is created using a stapling device, and the rest of the stomach (roughly 2/3) is removed. The sleeve is about the size of a banana. The smaller stomach restricts the amount of food you can consume in a single sitting, providing a quicker sense of fullness and decreased appetite. Food passes through the digestive tract in the usual order, allowing it to be fully absorbed in the body.
