Sleeve to SADI-S Conversion.

If your journey with a Gastric Sleeve has plateaued or you're facing challenges, transitioning to a SADI-S revision may offer the results you're seeking. Under the expert care of trusted bariatric surgery SADI duodenal switch expert in Austin and Cedar Park, Texas Dr. Sashidhar Ganta, we focus on optimizing your health outcomes and achieving sustainable weight loss.

Background and approach

The metabolic benefit of SADI-S

SADI-S combines a sleeve with a new connection from the duodenum to a later part of the small intestine. The sleeve removes much of the stomach region that produces ghrelin, a hormone involved in hunger. The intestinal connection changes when nutrients meet digestive juices and which intestinal cells encounter food.

These changes influence natural signals such as GLP-1, which supports insulin release in response to elevated glucose, and PYY, which contributes to fullness. Research in people shows altered meal-related hormone responses after SADI-S; the pattern is not identical to traditional duodenal switch. Reduced calorie absorption and changes in insulin sensitivity also contribute to its metabolic effects.

For appropriately selected patients, this combination can provide substantial weight loss and improvement in type 2 diabetes and other weight-related conditions. The same intestinal changes make protein, vitamin and mineral intake especially important. A clear supplementation plan, periodic blood tests and lifelong follow-up help protect your nutrition as your weight and health improve. Your surgeon tailors the procedure and long-term plan to your individual needs.

The metabolic benefit The sleeve removes most of the ghrelin-producing stomach tissue, helping reduce hunger naturally. The intestinal bypass enhances the body’s natural GLP-1 response after meals, supporting earlier fullness, blood sugar control, and long-term weight maintenance. It also deliberately reduces calorie and nutrient absorption—called malabsorption—to contribute to weight loss. Nutrition follow-up and prescribed supplements are part of long-term care.

Revision eligibility is individualized. Your previous operation, symptoms, reflux, nutritional status, weight response and metabolic health guide the evaluation. Primary-surgery BMI thresholds alone do not determine whether revision is appropriate. Dr. Ganta reviews your records and anatomy to recommend a plan suited to your clinical needs.

What is Conversion from Gastric Sleeve to SADI duodenal switch?

The conversion from a Gastric Sleeve to SADI-S at NuSelf involves modifying and revising the existing sleeve and adding a single anastomosis duodeno-ileal bypass to significantly improve metabolism and reduce the length of the intestine absorbing calories. This revision is designed for individuals who need further intervention to achieve their weight loss goals or to address metabolic conditions and achieve long term success. It combines the benefits of sleeve gastrectomy with intestinal bypass, offering a powerful solution for sustained weight loss and health improvement.

How is the Sleeve to SADI Revision Performed?

In the Sleeve to SADI revision, in most practices, the previously created gastric sleeve is kept intact while a portion of the small intestine is bypassed. However at NuSelf we believe in no compromise approach to maximize results and longevity. Therefore Dr. Ganta revises the gastric sleeve in most cases to create more restriction along with the Sadi duodenal switch. The procedure reroutes the small intestine to a loop of ileum, significantly reducing the absorptive surface and enhancing weight loss and metabolic effects. Performed using laparoscopic or robotic techniques, this procedure minimizes recovery time and maximizes the safety and effectiveness of the revision.
