What Is SADI-S?

Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a modern take on the duodenal switch (biliopancreatic diversion with duodenal switch) procedure.

Very obese patients may have a hard time achieving their weight loss goals. With your health on the line, you need an effective solution.

 SADI-S offers aggressive weight loss potential as it combines restrictive and malabsorptive components. 

ALO Bariatrics has helped thousands of patients achieve their weight loss goals and can help you do the same.


SADI-S in 
Tijuana, Mexico

When compared to gastric bypass and duodenal switch, SADI-S is easier and faster to perform. Because SADI-S requires less rerouting of the intestines and only has a single anastomosis, patients experience faster surgery times and reduced risk of intestinal leakage.

Faster, Simpler, and Safer Surgery

SADI-S can help you lose 80% or more of your excess weight in 12-18 months and manage weight-related health conditions like type 2 diabetes, sleep apnea, and high blood pressure. SADI-S has shown transformative results as both a primary bariatric surgery and a revision.

Exceptional Results

Improved Quality of Life

Patients who undergo the SADI-S procedure lose a lot of their excess weight in the first three months, meaning they can experience a slimmer figure and easier mobility shortly after surgery. The effects of SADI-S can be long-lasting when patients are committed to their new lifestyle.

Duodenal switch procedures start with a sleeve gastrectomy, the removal of 80% of the stomach. The surgeon then reroutes the intestines to shorten the path your food takes. 

SADI-S is a similar procedure. It starts with a sleeve gastrectomy, then the new stomach sleeve is sewn to a loop of the small intestine to bypass most of the bowel. 

The main difference between the biliopancreatic diversion with duodenal switch and SADI-S procedures is the single anastomosis (reconnection within the gastrointestinal tract). While duodenal switch requires two, SADI-S requires just one.

How SADI-S Aids in Weight Loss

Sleeve gastrectomy is a restrictive weight loss procedure, meaning it reduces the amount of food your stomach can hold. It helps you feel fuller faster, and with less food. It also removes the part of the stomach that produces most of your ghrelin, the hunger hormone, lowering your appetite. 

The gastric bypass portion of the surgical procedure reroutes the intestines to result in a malabsorptive effect, so your body absorbs fewer calories. 

This combination leads to consistent, healthy, and sustainable weight loss.
