SADI-S (Single Anastomosis Duodenal-Ileal Bypass with Sleeve) is rapidly becoming the gold standard for high-BMI patients and bariatric revisions. Think of it as "The Sleeve 2.0." It combines the best parts of a Gastric Sleeve with the powerful metabolic changes of a Gastric Bypass, but using a safer, modernized, single-connection technique.
It works through a powerful dual-action approach:
Unlike a traditional Roux-en-Y Gastric Bypass, the SADI-S technique preserves your pylorus—the natural valve at the bottom of your stomach. This crucial detail allows for a much more natural digestion process, prevents the dreaded "dumping syndrome," and severely decreases the risk of extreme nutritional deficiencies or marginal ulcers.
SADI-S is a powerful metabolic tool. Dr. Sandy Martinez will personally review your medical history to ensure this is your safest path to success. SADI-S is highly recommended for:
Patients with a very high Body Mass Index often face metabolic resistance that restriction alone cannot conquer. SADI-S offers the highest expected excess weight loss percentage of any bariatric surgery.
If your gut hormones have adapted to your Gastric Sleeve and the scale is creeping back up, SADI-S is the ultimate solution to restart your weight loss without starting from scratch.
Clinical data shows that SADI-S has an exceptional success rate in putting severe Type 2 Diabetes and high cholesterol into long-term remission.

Choosing bariatric surgery abroad can feel overwhelming. Dr. Sandy Martinez removes the stress by combining world-class surgical expertise with a premium luxury experience.
In this video, I explain the SADI-S, a highly advanced and modern evolution of the traditional Duodenal Switch. While a standard Duodenal Switch involves two intestinal connections, the SADI-S simplifies this into a single loop (Single Anastomosis). It powerfully combines a gastric sleeve to restrict food intake with an intestinal bypass to reduce calorie absorption. As the world's leading expert in this procedure, I break down exactly how this dual-action surgery delivers maximum weight loss and metabolic healing with an even safer, streamlined technique.
