Weight Loss - Top 5 Reasons Patients Choose SADI-S

Top 5 Reasons Patients Choose SADI-S for Weight Loss

When it comes to effective, long-term weight loss solutions, the Single Anastomosis Duodeno–Ileal Bypass with Sleeve Gastrectomy (SADI-S) is gaining popularity among patients and surgeons alike. As an evolution of earlier bariatric surgeries, SADI-S combines the benefits of a gastric sleeve with a simplified bypass, offering impressive weight loss outcomes and improved metabolic health.

So, why are more patients choosing SADI-S over traditional procedures like gastric bypass or sleeve gastrectomy alone?

"As a bariatric surgeon, I’ve seen firsthand how life-changing this procedure can be. Here are the top 5 reasons patients opt for SADI-S as their preferred weight loss surgery:"

1. Superior Loosing Weight Results

One of the primary reasons patients choose SADI-S is because of its significant and sustained weight loss outcomes. Studies show that patients lose, on average, 80–90% of their excess weight within the first 12–18 months after surgery. This makes it one of the most effective bariatric procedures available today.

Unlike other surgeries that may result in weight regain after a few years, SADI-S offers long-term durability, especially for patients with higher BMI or those who didn’t succeed with previous procedures.

2. Better Control of Type 2 Diabetes and Metabolic Disorders

SADI-S isn’t just a weight loss surgery—it’s also a powerful metabolic procedure. By rerouting the intestines, SADI-S dramatically improves insulin sensitivity and reduces blood sugar levels.

Many patients with type 2 diabetes experience rapid improvement—often seeing their blood sugar normalize within days to weeks, even before significant weight loss occurs. This has made SADI-S a top choice for individuals with obesity-related conditions such as:

Type 2 diabetes
High cholesterol
High blood pressure
Fatty liver disease

3. Lower Risk of Nutritional Deficiencies Compared to Traditional Bypass

While traditional duodenal switch (DS) procedures offer excellent weight loss, they can come with a higher risk of malnutrition due to complex rerouting of the small intestine. SADI-S simplifies this by using only one intestinal connection (anastomosis) instead of two, reducing the risks of leakage and complications.

4. Reduced Hunger and Better Appetite Control

SADI-S includes a sleeve gastrectomy, which removes approximately 80% of the stomach, including the section that produces the hunger hormone ghrelin. This results in:

Decreased appetite
Early satiety (feeling full sooner)
Lower calorie intake without feeling deprived

For patients who have struggled with constant hunger or binge eating, this procedure can offer a much-needed sense of control and freedom from cravings, making lifestyle changes more sustainable.

5. An Excellent Option for Revision Surgery

SADI-S is also a popular choice for patients who have had unsuccessful weight loss surgeries in the past—such as sleeve gastrectomy alone or gastric banding. It serves as a powerful revision option that boosts weight loss results while correcting metabolic issues.

Because it retains the sleeve component and adds only one intestinal rerouting, SADI-S offers an effective “upgrade” with less surgical complexity and lower risk than full DS or Roux-en-Y bypass.

Final Thoughts

Choosing a weight loss surgery is a personal and life-changing decision. With its impressive weight loss results, strong metabolic benefits, and lower complication risks, SADI-S has emerged as a top-tier option for individuals seeking long-term success in their weight loss journey.

However, it’s important to consult with a qualified bariatric surgeon to determine if SADI-S is the right fit for your body, health conditions, and lifestyle goals.
