At Bariatric Guru in Los Angeles, we specialize in Single-Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI), a cutting-edge surgical procedure for treating obesity. This advanced surgery, performed by our expert bariatric surgeon, Dr. Sepehr Lalezari, offers a substantial and sustainable solution for individuals struggling with severe obesity.
What is SADI Surgery?
SADI is a newer form of bariatric surgery that combines elements of a sleeve gastrectomy with a duodenal switch. The procedure involves two main steps: creating a sleeve gastrectomy to reduce the size of the stomach and bypassing a portion of the small intestine to decrease nutrient and calorie absorption. This combination enhances weight loss outcomes and helps manage obesity-related conditions.
Key Features of SADI Surgery
- Effective Weight Loss
SADI significantly reduces the body’s ability to absorb calories, leading to substantial long-term weight loss.
- Nutrient Absorption
Although SADI involves bypassing a portion of the small intestine, it allows for better nutrient absorption compared to traditional duodenal switch surgery.
- Minimally Invasive
Utilizing advanced laparoscopic techniques, the procedure minimizes recovery time and reduces the risks of complications.
Benefits of SADI Rapid Weight Loss Surgery
- Significant and Rapid Weight Loss
Patients typically experience rapid and substantial weight loss following SADI surgery, often more pronounced than with other bariatric procedures.
- Improvement in Comorbid Conditions
SADI is particularly effective in improving or resolving obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea.
- Reduced Hunger
The hormonal changes induced by the surgery help decrease appetite and increase feelings of fullness.

Is SADI Right for You?
Candidates for SADI Surgery include individuals who:
- Have a Body Mass Index (BMI) of 40 or higher, or more than 35 with serious obesity-related health issues.
- Have previously undergone other forms of weight loss surgery but did not achieve or maintain successful weight loss.
- Are prepared for significant lifestyle changes and are committed to following a comprehensive post-operative diet and exercise plan.
What to Expect During the SADI Procedure
During the SADI procedure, Dr. Lalezari first performs a sleeve gastrectomy, removing a large portion of the stomach. He then rearranges the small intestine to bypass a significant length of the bowel, which decreases the absorption of calories and nutrients. The procedure typically requires a hospital stay of several days, allowing for initial recovery and monitoring.
Post-Operative Care and Support
At Bariatric Guru, we provide extensive support and follow-up care to ensure optimal results and assist with the necessary lifestyle adjustments post-surgery. This includes nutritional counseling, physical activity recommendations, and regular check-ups to monitor health improvements and any potential adjustments needed for the surgery.
Frequently Asked Questions (FAQ)
SADI-S combines two mechanisms to achieve weight loss:
- Restriction: The sleeve gastrectomy component reduces the size of the stomach, limiting the amount of food that can be consumed.
- Malabsorption: The bypassed section of the small intestine reduces the absorption of calories and nutrients.
Patients undergoing SADI-S can expect significant excess weight loss, similar to the results seen with the traditional duodenal switch surgery. This often translates to substantial weight loss and improvement in obesity-related conditions over time.
As with any surgical procedure, SADI-S carries potential risks and complications, including:
- Nutritional Deficiencies: Due to the malabsorptive component of the surgery, patients may experience deficiencies in vitamins and minerals, necessitating lifelong supplementation.
- Surgical Complications:Β Risks include infections, leakage at the surgical connections, and other typical surgical risks.
SADI-S offers a balance between the restrictive and malabsorptive components, providing significant weight loss similar to the duodenal switch but with a potentially simpler surgical process. It is more effective than restrictive-only procedures like the gastric sleeve but requires a commitment to managing potential nutritional deficiencies.
Recovery times can vary based on individual circumstances, but most patients can expect to return to normal activities within a few weeks. The minimally invasive nature of the procedure often results in quicker recovery times compared to more invasive surgeries.
