Duodenal Switch

The Duodenal Switch Surgery, at ALO Bariatrics, is a type of combined malabsorptive and restrictive weight loss surgery. The duodenal switch is known by multiple names, including DS and biliopancreatic diversion with duodenal switch. This surgery decreases both the quantity of food that can be accommodated by the stomach and the number of calories that can be absorbed and used by the body.
The duodenal switch (DS) procedure, also known as biliopancreatic diversion with duodenal switch (BPD-DS) or gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect.
Biliopancreatic diversion with duodenal switch (BPD/DS), performed by surgeon Alejandro Lopez, is a combination of bariatric surgery techniques used to create a smaller stomach and limit nutrient and calorie absorption, resulting in massive weight loss. It is intended for patients with a body mass index (BMI) of 50 or greater. Due to its complexity and increased risks, BPD/DS should only be performed by a highly experienced bariatric surgeon. Dr. Lopez private practice, recognized by the Mexican College of Surgery for Obesity and Metabolic Diseases as a Center of Excellence, has a very high rate of patient success.

About The Surgery

Duodenal Switch or BPD/DS is considered the best surgery for patients with a BMI greater than 50 who wish to improve obesity-related health problems. The average amount of excess weight lost after the procedure is approximately 70%. It is usually performed laparoscopically (using small incisions, small surgical tools, and an endoscope). In the first stage of the procedure, a large portion of the stomach (approximately 80%) is removed so that it resembles a tube or sleeve (as in sleeve gastrectomy). The second stage involves rerouting the intestine so the body has less time to absorb calories and fat. This is accomplished by connecting the end of the large intestine to the first section of the small intestine, called the duodenum. Following surgery, you will stay in the hospital for two to three days so that Dr. Lopez can be certain that your modified digestive system is functioning properly. Afterward, you will require periodic checkups. You will also need to take supplemental vitamins every day for the rest of your life to avoid developing nutritional deficiencies. As with other bariatric surgeries, you must maintain a healthy lifestyle that includes eating small nutritious meals and engaging in regular physical activity.


DS or BPD/DS can improve serious obesity-related health complications including diabetes, high cholesterol, high triglycerides, hyperlipidemia, and obstructive sleep apnea. Other benefits include:

Reduced incidence of dumping syndrome as compared to gastric bypass surgery. Dumping syndrome is a group of symptoms that can occur after surgical removal of portions of the stomach.
It involves a more normal diet that is better tolerated compared to diets required following other types of bariatric surgery.
Since none of the intestine is removed, the malabsorbtive aspect of the surgery can be reversed, if necessary.
