Duodenal Switch
Expected weight loss 80-90% of excess weight
Description of Duodenal Switch
This procedure offers the ability to eat larger portions foods than gastric bypass or adjustable gastric banding and has reliable and long lasting weight loss. You may experience more bowel movements and need to closely monitor your vitamin, protein and mineral levels.
The stomach is reduced in size to a long, tube like vertical pouch, 4-5 ounces in size with moderate restriction of food intake. Dr. Feng divides the small intestine to separate food from the digestive juices, causing significant malabsorption. This surgery is best for patients with BMI of 50 and above. |
