The other side of the procedure changes the structure of the digestive tract. A portion of the small intestine is re-routed to reduce the body’s absorption of food by making a shorter path for food to travel before it reconnects with the bypassed portion of the small intestine. At the connection, the two pathways merge and the bypassed portion of the small intestine can continue to assist in digestion through the remainder of the digestive tract by delivering fluids necessary for proper digestion.
This dual-sided approach addresses two different options common in bariatric surgery. Patients who undergo a duodenal switch procedure will only be able to consume a fraction of the food they were accustomed to eating, and of that food, only a fraction of it will be absorbed by the body, resulting in rapid weight loss.
Metz says that duodenal switch weight loss surgery is saving lives, but it’s up to the patient to want to make the change. “We’re seeing an over 80% success rate and it’s fantastic,” Metz says. “But the hardest thing is getting patients in the door and admitting they need some help.”
The procedure is showing amazing results and is responsible for the near elimination of type 2 diabetes in some patients. On average, participants who undergo duodenal switch maintain a 79% loss of excess body weight after 2 years. Duodenal switch patients are also more likely to have control of obesity-related conditions like diabetes, high blood pressure and sleep apnea after surgery, especially among participants who started out with a BMI greater than 50.
