What is a Duodenal Switch (SADI-S) Surgery?
Duodenal Switch Surgery (SADI-S), also known as Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy, is an innovative bariatric procedure designed for significant, sustained weight loss. Unlike traditional gastric bypass surgeries, Duodenal Switch Surgery combines sleeve gastrectomy with intestinal bypass, effectively reducing calorie absorption. During this procedure, approximately 80% of the stomach is removed, significantly decreasing hunger hormones and restricting food intake. Subsequently, surgeons bypass a large portion of the small intestine, shortening the digestive tract to limit nutrient absorption. As a result, Duodenal Switch Surgery promotes rapid and durable weight loss, often benefiting individuals suffering from severe obesity or related metabolic disorders such as diabetes.
The benefits of SADI-S surgery extend beyond weight loss, positively impacting metabolic health by significantly improving conditions like type 2 diabetes, hypertension, and high cholesterol. Duodenal Switch Surgery has shown superior results in maintaining long-term weight reduction compared to other bariatric procedures, thanks to its dual mechanism of restrictive and malabsorptive components. Patients undergoing this surgery typically experience enhanced quality of life, improved mobility, and reduced risk of obesity-related diseases. However, lifelong nutritional supplementation and regular medical follow-ups are essential post-surgery due to potential vitamin and mineral deficiencies. Ideal candidates for Duodenal Switch Surgery are individuals who have not successfully lost weight through conventional methods or previous bariatric surgeries.

How SADI-S Surgery Works
SADI-S surgery, also known as Single Anastomosis Duodeno-Ileal bypass with Sleeve Gastrectomy, is an advanced bariatric procedure combining restrictive and malabsorptive elements to achieve substantial weight loss. First, the surgeon performs a sleeve gastrectomy, removing about 80% of the stomach and forming a narrow, banana-shaped stomach pouch. This significant stomach reduction decreases appetite by minimizing the production of hunger-related hormones, leading to controlled food intake. Next, the surgeon reroutes the small intestine by connecting the shortened duodenum directly to the ileum, bypassing a large segment of the digestive tract. This single anastomosis limits nutrient and calorie absorption, intensifying weight loss effectiveness. As a result, Duodenal Switch Surgery promotes both rapid and sustainable weight reduction, significantly benefiting patients with severe obesity.
In addition to significant weight loss, Duodenal Switch Surgery profoundly impacts metabolic function by promoting hormonal changes beneficial for obesity-related illnesses such as type 2 diabetes and high cholesterol. Unlike the traditional approach, the modified duodenal switch uses a simplified, single intestinal connection, reducing operative time and surgical risks. The shorter digestive tract means fewer calories and fats are absorbed, directly supporting sustained weight loss and improved metabolic health. Despite these advantages, patients require lifelong nutritional monitoring and vitamin supplementation to prevent deficiencies. Ideal candidates for SADI-S are those with severe obesity who have previously struggled to achieve lasting results through conventional weight loss methods.
Differences Between Duodenal Switch and Other Bariatric Surgeries
Duodenal Switch (SADI-S) vs Gastric Bypass
Duodenal Switch Surgery (SADI-S) and Gastric Bypass are effective bariatric procedures but differ significantly in technique and outcomes. SADI-S combines sleeve gastrectomy with a single intestinal bypass, dramatically reducing calorie absorption and offering superior long-term weight loss results. Gastric Bypass involves creating a small stomach pouch and rerouting the intestine to limit food intake and calorie absorption. Compared to Gastric Bypass, Duodenal Switch Surgery typically results in greater weight reduction and significant improvements in obesity-related conditions like type 2 diabetes, hypertension, and high cholesterol. However, SADI-S requires more extensive nutritional monitoring and supplementation due to increased malabsorption risks. Ultimately, Duodenal Switch Surgery suits patients seeking enhanced weight loss and metabolic benefits when traditional bariatric methods have proven inadequate.
Duodenal Switch (SADI-S) vs Gastric Sleeve
Duodenal Switch Surgery (SADI-S) and Gastric Sleeve surgery differ significantly in their surgical approach and long-term outcomes. Duodenal Switch Surgery combines restrictive sleeve gastrectomy with intestinal bypass, substantially limiting calorie and nutrient absorption, resulting in greater and more sustainable weight loss. Conversely, Gastric Sleeve involves only the restrictive portion, removing approximately 80% of the stomach without rerouting the intestine. While Gastric Sleeve effectively reduces hunger and food intake, Duodenal Switch Surgery further enhances metabolic changes, significantly improving conditions like type 2 diabetes, high cholesterol, and hypertension. However, SADI-S surgery typically demands lifelong vitamin supplementation and regular monitoring due to malabsorption risks. In contrast, Gastric Sleeve involves fewer nutritional deficiencies and lower maintenance but may yield comparatively less weight loss.
Duodenal Switch (SADI-S) vs Gastric Band
Duodenal Switch Surgery (SADI-S) and Gastric Band are distinctly different bariatric techniques regarding their effectiveness, complexity, and patient outcomes. Duodenal Switch Surgery combines sleeve gastrectomy with intestinal bypass, significantly reducing calorie and nutrient absorption, and providing superior long-term weight loss. In contrast, Gastric Band involves placing an adjustable silicone band around the upper stomach, restricting food intake without altering the digestive tract. While Gastric Band is less invasive and reversible, its weight loss results are generally slower and less substantial than those achieved with Duodenal Switch Surgery. Additionally, SADI-S offers notable metabolic improvements, including substantial relief from type 2 diabetes, hypertension, and elevated cholesterol levels. However, due to its malabsorptive nature, Duodenal Switch Turkey requires lifelong nutritional supplements and regular follow-ups, whereas Gastric Band patients face fewer nutritional deficiencies but often require ongoing adjustments and experience less significant weight reduction.

The Duodenal Switch Procedure
The duodenal switch surgery is a complex operation performed by expert bariatric surgeons using advanced techniques to ensure safety and effectiveness.

Step-by-Step Overview of Duodenal Switch Surgery
Step 1: Anesthesia and Preparation
Initially, the patient is placed under general anesthesia to ensure comfort throughout the surgery. The surgeon makes small, minimally invasive laparoscopic incisions in the abdomen to insert surgical instruments and a camera for clear visualization.
Step 2: Sleeve Gastrectomy
The surgeon removes about 80% of the stomach, creating a smaller, sleeve-shaped pouch. This reduction significantly limits the amount of food intake, helping patients feel full quickly and substantially reducing hunger hormones.
Step 3: Division of the Duodenum
The first section of the small intestine, known as the duodenum, is carefully separated just below the stomach. This is an essential step to prepare for the intestinal bypass.
Step 4: Intestinal Bypass (Anastomosis)
The surgeon reconnects the shortened duodenum directly to a lower part of the small intestine called the ileum. This single anastomosis significantly shortens the path food travels through the digestive system, leading to reduced absorption of calories and nutrients.
Step 5: Inspection and Testing
After establishing the new connection, the surgeon carefully inspects the surgical sites to ensure no leaks or complications. This includes testing the connection by introducing dye or air to confirm the integrity of the anastomosis.
Step 6: Closing the Incisions
Finally, the surgeon removes the laparoscopic instruments and camera, carefully closes the small incisions with stitches or surgical staples, and applies dressings or sterile bandages.
Step 7: Postoperative Care and Monitoring
Immediately after surgery, patients are moved to a recovery area for careful monitoring. Pain management, dietary guidelines, nutritional supplementation, and regular follow-up appointments are critical for successful recovery and sustained weight-loss results after Duodenal Switch Surgery.
Anesthesia and Surgical Safety Measures
Turkish clinics prioritize patient safety through:
- Advanced anesthesia protocols to reduce risks and ensure comfort.

However, patients must commit to lifelong nutritional supplementation and regular follow-up appointments to maintain their health after surgery. Choosing to have Duodenal Switch Turkey allows patients access to affordable yet world-class bariatric treatment, combining exceptional medical care with a favorable recovery environment, further enhancing their overall post-surgical experience.

Potential Risks and Complications of Duodenal Switch
Although duodenal switch (SADI-S) is a highly effective and safe procedure, like all surgeries, it carries some potential risks and long-term considerations. Understanding these risks and how they are managed can help patients make informed decisions.
Common Side Effects
- Nausea and Vomiting: Often occurs during the initial recovery period as the body adjusts to smaller food portions.
- Diarrhea or Loose Stools: A result of the malabsorptive component of the surgery, which alters digestion.
- Fatigue: Temporary and common due to reduced calorie intake during recovery.
Long-Term Considerations and Risk Mitigation
- Nutrient Deficiencies: The bypassed portion of the small intestine limits nutrient absorption, potentially leading to deficiencies in:
- Vitamins (B12, D, A)
- Minerals (calcium, iron, zinc) To mitigate this, patients must take lifelong supplements and attend regular check-ups.
- Gastric Leakage: A rare but serious complication that occurs when the new stomach pouch or intestinal connections do not heal properly. This risk is minimized with advanced surgical techniques and thorough post-op monitoring in Turkish clinics.
- Weight Regain: Though rare, weight regain can occur if dietary and lifestyle guidelines are not followed.
