Duodenal Switch

The duodenal switch is a powerful, two-part weight loss surgery that combines a sleeve gastrectomy with a significant bypass of the small intestine. It restricts how much you can eat while also reducing the absorption of calories and nutrients, making it one of the most effective procedures for long-term weight loss and metabolic improvement. This surgery is typically reserved for patients with severe obesity or those with poorly controlled diabetes and is performed using minimally invasive techniques, often with the Da Vinci XI robotic system for precision and reduced recovery time.

Pros:

Greatest long-term weight loss (up to 80–90% of excess body weight)

Highest rates of diabetes remission

Maintains a functioning pyloric valve, reducing risk of dumping syndrome

Strong appetite suppression and long-lasting satiety

Effective for patients with severe obesity and metabolic disease

Cons:

Most complex bariatric procedure with two intestinal connections

Highest risk of nutrient deficiencies (fat-soluble vitamins, iron, calcium, protein)

Requires strict lifelong supplement regimen and lab monitoring
