What is Duodenal Switch Surgery?

Duodenal switch surgery, also known as biliopancreatic diversion with duodenal switch (BPD/DS), is the classic weight loss procedure that combines two strategies to achieve weight loss. The surgery includes reshaping the stomach into a smaller, sleeve-like pouch, which restricts food intake, and rerouting the small intestine to limit the absorption of calories and nutrients. This method helps patients manage their weight by controlling how much they eat and how efficiently they absorb nutrients. The surgery provides an efficient way to shed pounds, leading to great results over time. On average, patients lose 78% extra body weight in the first year.

How Duodenal Switch Works

The procedure consists of two main parts:

  1. Sleeve Gastrectomy: A portion of the stomach is removed, reshaping it into a smaller, sleeve-like structure. This reduces the amount of food a person can consume at one time.
  2. Intestinal Bypass: The duodenum, which is the initial segment of the small intestine, is separated immediately after the stomach. The lower portion of the small intestine is then reattached to the new stomach pouch, bypassing a large section of the small intestine. This alteration decreases the absorption of calories and nutrients.

The combination of restrictive and malabsorptive features helps with weight loss by curbing food intake and limiting calorie absorption. This approach also influences hunger and metabolic hormones, which can extend the feeling of being satisfied for longer periods.

Single Loop Duodenal Switch Surgery (SADI-S)

The Single-Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S) is the modified version of the duodenal switch but with a simpler approach. In this surgery, the stomach is made smaller, like in a sleeve gastrectomy, and the first part of the small intestine (the duodenum) is cut just after the stomach. The lower part of the small intestine (the ileum) is then attached directly to the smaller stomach, skipping most of the small intestine.

SADI-S offers similar benefits to the duodenal switch, such as limiting food intake and nutrient absorption, but it’s simpler because it involves only one intestinal connection. This surgery may result in a shorter surgery and a faster recovery time.

Dr. Rodriguez Lopez has significant experience performing the SADI-S procedure and is highly knowledgeable about its techniques. He has taken part in many bariatric congresses and has presented on the SADI-S surgery.

Duodenal Switch Weight Loss Timeline

Patients can expect to lose about 78% of their excess body weight due to the combined effects of the two weight-loss components. In the first three months following duodenal switch surgery, patients typically lose between 1/2 pound and 1 pound per day.

3-6 Months: Weight loss will continue steadily as patients adjust to their new diet and lifestyle changes. They can expect to lose on average 35% excess weight. Having stalls or not losing weight during the first three months is completely normal because your body changes.

6-12 Months: During this period, majority of patients will lose the most weight—roughly 55% excess weight.

12-18 Months: Weight loss will stabilize around this time and patients will have lost 75-80% excess weight.

2-5 Years: Patients must maintain their weight loss by following the post-op diet, being more active, and taking bariatric vitamins. They can expect to lose up to 82% excess weight.

**Please keep in mind that everyone’s body responds differently—some may experience quicker results than others. Don’t be discouraged.

Pros and Cons of Duodenal Switch


  • Reversible procedure: The malabsorptive component can be reversed, functioning independently as a gastric sleeve
  • Significant weight loss: The duodenal switch leads to one of the highest percentages of excess weight loss among bariatric surgeries
  • Improve health: Many obesity-related health conditions such as type 2 diabetes, hypertension, PCOS and sleep apnea improve or resolve after surgery
  • Sustained weight loss: Patients often maintain their weight loss over the long term


  • Vitamin Deficiencies: The malabsorptive nature of the surgery can lead to deficiencies in vitamins and minerals, requiring lifelong supplements and monitoring
  • Risk of gallstones: Gallstones are a frequent risk factor associated with post-operative weight loss
  • Complexity: The duodenal switch is a complex surgery, which may require a longer hospital stay and recovery time compared to other bariatric procedures
