Patient-Friendly Explanation

SADI-S is a weight-loss surgery that reduces the size of the stomach and shortens the path food takes through the intestines. It helps patients lose a large amount of weight while keeping the procedure to a single surgical connection. Most people stay in hospital for two to three nights after the operation.

Clinical Definition

SADI-S combines a sleeve gastrectomy with a single-loop duodenal-ileal bypass, creating one anastomosis rather than the two used in traditional biliopancreatic diversion with duodenal switch. Weight loss results from both gastric restriction and moderate malabsorption of calories and nutrients. It is typically considered for patients with a body mass index above 50 kg/m2, or for those who have not achieved sufficient weight loss with sleeve gastrectomy alone.

Why It Matters

SADI-S produces powerful weight loss and improvement in obesity-related conditions such as type 2 diabetes, but it requires lifelong vitamin and mineral supplementation and careful follow-up.
