SADI-S
SADI-S is one of the most effective bariatric options available today, offering powerful weight-loss and metabolic benefits for patients who need more than a standard sleeve. At Clinic 360, this advanced surgery is performed by our experienced bariatric team in our state-of-the-art surgical facility, with comprehensive long-term support to help you achieve lasting results.
What is SADI‑S?
SADI‑S (also called single‑anastomosis duodenal switch) starts with a vertical sleeve gastrectomy (gastric sleeve surgery) and then connects the first part of the small intestine (duodenum) to a more distant segment of small bowel. Food still takes a natural route, but part of the intestine is bypassed—delivering restriction + a stronger metabolic/absorption change.
Why some patients consider it:
- Greater average weight‑loss potential vs. gastric sleeve alone
- Strong type 2 diabetes and metabolic improvements
- One bowel connection (vs. two in classic duodenal switch)
What is Gastric Sleeve Surgery ? ( Vertical Sleeve Gastrectomy or VSG )
Gastric Sleeve Surgery removes a portion of the stomach to create a smaller, banana‑shaped sleeve. It reduces hunger and portion sizes while keeping food on a normal path (no intestinal rerouting).
Why it’s our flagship:
- Powerful, well‑studied weight‑loss for many patients
- Simpler anatomy and vitamin routine vs. bypass procedures
- Often a good first‑line surgical option
Which is Right for Me?
Every patient is unique. During your consultation, our surgeons review your health history, weight-related conditions (such as diabetes or sleep apnea), prior surgeries, reflux symptoms, and personal goals to help determine the safest and most effective option.
Gastric Sleeve (VSG)
A great choice if you want a powerful, simpler procedure with fewer long-term nutritional demands—ideal for many first-time bariatric patients who meet the candidacy criteria.
SADI-S
Recommended for patients who need a stronger metabolic effect, have a higher BMI or significant metabolic disease, or those considering revision surgery after a previous sleeve that no longer provides sufficient weight loss or diabetes control.
Your candidacy for either procedure is determined through a comprehensive assessment by our bariatric surgeons.
Gastric Sleeve Surgery vs. SADI-S
Gastric Sleeve Surgery
VSG (Vertical Sleeve Gastrectomy)- Main Approach: Reduces stomach size only
- Expected Weight Loss: ~60–70% excess weight loss
- Metabolic Impact: Strong
- Ideal For: Patients needing significant weight loss, fewer nutritional demands
- Impact on Hunger Hormones: High ghrelin reduction
- Diabetes Improvement: Very good
- Nutrient/Mineral Risk: Moderate
- Digestive Changes: Minimal, more “physiologic”
- Surgery Time: Shorter
- Recovery: Typically faster
- Best For: First-time bariatric patients
SADI-S
(Single Anastomosis Duodeno-Ileal Bypass)- Main Approach: Sleeve + intestinal bypass
- Expected Weight Loss: ~80–90% excess weight loss (more powerful)
- Metabolic Impact: Very strong (more hormonal + malabsorption effects)
- Ideal For: Patients needing maximal weight loss or have weight regain after sleeve
- Impact on Hunger Hormones: High ghrelin reduction + added metabolic change
- Diabetes Improvement: Often excellent, higher remission rates
- Nutrient/Mineral Risk: Higher, requires strict vitamins + monitoring
- Digestive Changes: More rerouting; may cause softer stools / malabsorption
- Surgery Time: Slightly longer
- Recovery: Similar timeframe, but more long-term follow-up
- Best For: Revision from sleeve or patients with BMI > 50

SADI-S Surgery FAQs
What does SADI-S stand for?
SADI-S stands for Single Anastomosis Duodeno-Ileal Bypass with Sleeve.
It is an advanced metabolic weight loss surgery that combines a gastric sleeve with an intestinal bypass to support long-term weight loss and metabolic health.
How much weight can you lose with SADI-S?
Weight loss varies by individual, but many patients may lose approximately 70 to 90 percent of excess body weight over time when SADI-S surgery is combined with structured aftercare, nutrition guidance, and lifestyle support.
Is SADI-S safer than gastric bypass?
SADI-S is considered a safe and effective bariatric procedure when performed by experienced surgeons.
It involves one intestinal connection instead of two, which may simplify the procedure compared to traditional gastric bypass.
How much does SADI-S surgery cost in Toronto?
At Clinic 360, the cost of SADI-S surgery in Toronto is $22,000.
This includes a comprehensive 6-Year Aftercare Program with follow-ups, nutritional guidance, and long-term support. Financing options may be available.
Is SADI-S covered by OHIP?
SADI-S surgery is not covered by OHIP when performed in a private bariatric clinic, such as Clinic 360.
Patients may choose private treatment to reduce wait times and access structured long-term aftercare.
Do you need vitamins after SADI-S?
Yes. Because SADI-S changes nutrient absorption, lifelong vitamin and mineral supplementation and routine blood work are required to maintain optimal health.
Can SADI-S fail?
Weight loss results depend on many factors including eating habits, activity level, and follow-up care.
While SADI-S is a powerful metabolic tool, long-term success requires lifestyle changes and ongoing medical support.
Is SADI-S permanent?
Yes. SADI-S surgery creates permanent anatomical and metabolic changes.
However, patients can still influence their long-term results through nutrition, physical activity, and structured aftercare.
How long before you see weight loss results after SADI-S?
Weight loss typically begins soon after surgery.
Patients often notice significant changes within the first 3 to 6 months, with continued progress over 12 to 18 months when following their aftercare plan.
When can I return to work after SADI-S?
Many patients can return to light work within 2 weeks, depending on the type of job and individual recovery progress.
Can you get pregnant after SADI-S surgery?
Yes, pregnancy is possible after SADI-S surgery.
Patients are usually advised to wait 12 to 18 months before trying to conceive to allow weight and nutritional levels to stabilize.
Can weight regain happen years after SADI-S?
Weight regain can happen after any bariatric procedure.
Maintaining long-term results depends on nutrition habits, activity levels, and continued follow-up with your bariatric care team.
