SADI-S Surgery
An advanced bariatric procedure designed to support significant weight loss and improve metabolic health.
What Is SADI-S Surgery?
SADI-S stands for Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy. The procedure combines a gastric sleeve with an intestinal bypass to limit food intake and reduce the number of calories absorbed by the body.
During surgery, the stomach is reduced to a smaller sleeve shape. The first portion of the small intestine is then rerouted so food travels through a shorter digestive pathway. SADI-S may provide greater weight loss than a gastric sleeve alone.
Benefits of SADI-S Surgery
SADI-S may offer several potential benefits:
- Significant and sustainable weight loss
- Reduced hunger and improved portion control
- Fewer intestinal connections than traditional duodenal switch surgery
- Improvement in type 2 diabetes and other metabolic conditions
- An option for certain patients with a higher BMI
- A possible revision following previous gastric sleeve surgery
Because SADI-S changes nutrient absorption, patients must commit to lifelong vitamins, appropriate nutrition, and regular medical monitoring.
Is SADI-S Surgery Right for You?
SADI-S may be considered for patients who require a more powerful surgical weight-loss option or who have experienced insufficient weight loss or weight regain after gastric sleeve surgery.
Your bariatric surgeon will consider your BMI, medical history, nutritional health, previous procedures, and ability to follow long-term dietary and supplement recommendations before determining whether SADI-S is appropriate.
Frequently Asked Questions
Both procedures include a sleeve gastrectomy, but SADI-S also reroutes part of the small intestine. This adds a malabsorptive component that can support additional weight loss.
