Reduce appetite and calorie absorption to lose weight
SADI/SIPS (Single Anastomosis Duodeno-Ileo Bypass/Stomach Intestinal Pylorus Sparing Surgery) is a modified duodenal switch that aims to promote significant weight loss. This procedure combines two powerful weight loss mechanisms: restriction and malabsorption. First, a sleeve gastrectomy removes about 70% of the stomach, reducing food intake and appetite. Then, a single intestinal bypass reroutes digestion, limiting calorie absorption. Dr Mo Atalla offers SADI/SIPS as a primary weight loss surgery or a second stage surgery for patients needing additional weight loss after a gastric sleeve.

Benefits of SADI/SIPS surgery:
- Greater average weight loss than gastric sleeve or gastric bypass
- Minimal risk of dumping syndrome compared to gastric bypass
- Lower risk of internal hernia and ulceration
- Single intestinal reconnection simplifies surgery and recovery
- Reduces appetite by removing the stomach portion that produces Ghrelin
- Enhances weight loss by combining restriction and malabsorption
- Typically results in absorbing only 55-70% of ingested calories
- Laparoscopic procedure with a shorter hospital stay (1-2 nights)
- Can be performed as a second-stage surgery after a sleeve gastrectomy
How does SADI/SIPS surgery promote weight loss?
SADI/SIPS surgery promotes weight loss by combining restriction and malabsorption. The procedure begins with a sleeve gastrectomy, where about 70% of the stomach is removed. This reduces the amount of food you can eat and lowers levels of Ghrelin, the “hunger hormone,” helping you feel full sooner and for longer. With a smaller stomach, portion sizes naturally decrease, making it easier to maintain a low-calorie diet and sustain weight loss over time.
The second part of the surgery involves a single intestinal bypass, which alters digestion to limit calorie absorption. By rerouting food past a part of the small intestine, the body absorbs only 55-70% of the calories consumed. This combination makes SADI/SIPS highly effective while maintaining better nutrient absorption than traditional duodenal switch surgery.
How much weight can I lose with SADI/SIPS surgery?
With SADI/SIPS surgery, you can expect significant weight loss. As a primary procedure, most patients lose around 70-75% of their excess body weight. If you’ve previously had a gastric sleeve and need additional weight loss, SADI/SIPS as a second-stage surgery typically results in 45-50% excess weight loss. However, your final results will depend on your commitment to healthy eating, regular exercise, and lifelong supplement intake.
*Individual Results May Vary
Potential side effects or risks of SADI/SIPS surgery:
- Temporary nausea, vomiting, or bloating after surgery
- Risk of nutrient and vitamin deficiencies due to reduced absorption
- Need for lifelong vitamin and mineral supplementation
- Possible changes in bowel habits, including looser or more frequent stools
- Increased risk of bile reflux due to intestinal rerouting
- Potential for protein malabsorption, requiring a high-protein diet
- Risk of surgical complications such as leakage or infection (though rare)
- Possible weight regain if dietary guidelines are not followed
- Need for regular follow-ups to monitor nutritional health
Life after SADI/SIPS surgery: what you can expect
After SADI/SIPS surgery, your eating habits and lifestyle will need to adjust for long-term success. You’ll feel full faster due to your smaller stomach, and portion sizes will significantly reduce. You’ll need to focus on high-protein, nutrient-rich foods while avoiding excessive sugars and processed carbs to prevent digestive discomfort. Regular, lifelong vitamin and mineral supplementation will be essential to prevent deficiencies. You can maintain steady, healthy weight loss and improved overall well-being with ongoing follow-up care.
