Duodenal switch is a newer type of weight loss surgery. It is reserved for a certain subset of patients who are super-morbidly obese and have uncontrolled diabetes. The surgeon creates a gastric sleeve (reducing the stomach size by 80%) and rearranges the intestines reducing the amount of calories and minerals absorbed by the body.  The intestines are segmented and regrouped to separate food from the digestive juices. This surgery is like a hybrid between Gastric Sleeve and Gastric Bypass.

Patients generally experience a significant weight loss during the first 6 months after the surgery. According to statistics, one can expect to lose about 75% of their current excess weight by 12-18 months.  While there are many benefits to this procedure, there are also a lot of risks that lead to life-changing habits.  Because the intestines are rearranged to reduce the caloric intake, it also reduces the absorption of vitamin and minerals, which leads to malabsorption.  This can be serious as it affects your immune system and bone structure.  As a result, patients are required to take supplements, such as Vitamin A, Vitamin D, and calcium, daily for life.  Malabsorption can also cause frequent bowel movements, body odors, and serious malnutrition. 

Generally, after the surgery patients have to stay in the hospital overnight. This surgery is performed robotically to provide the safest and least invasive method to achieve weight-loss surgery. Only 10% of patients experience minor complications post-surgery, and only 5% face serious postoperative health problems. Depending upon the type of work you do, you will be able to return to work within 1-3 weeks. Although the first week will be focused on resting, you will have to walk around a good bit to decrease pain and prevent blood clots.

The results of Duodenal switch are amazing, but the follow up is a life-time commitment.  It is important that patients keep their appointments and follow the post-surgery guidelines.
