Biliopancreatic diversion is a less commonly known weight-loss procedure. It is typically performed as a single-step procedure but may involve two steps in specific cases. The first step is a sleeve gastrectomy, where a large portion of the stomach is removed, followed by an intestinal bypass in the second step. This procedure reduces food intake and limits the absorption of nutrients, proteins, and fats. Although it is effective for weight loss, it carries risks such as vitamin deficiencies and malnutrition. Biliopancreatic diversion is typically recommended for individuals with a BMI above 50.
