Pros and cons of the Duodenal Switch
The duodenal switch is a bariatric surgery technique for weight loss. It is not as common as other procedures such as the gastric bypass or the gastric sleeve, but he results are among the most succesful, specially when performed by an experienced bariatric surgeon.
- Patients achieve greater weight loss, usually over than 80% of excess weight
- The production of the ghrelin hormone which controls hunger is eliminated.
- Maintains the pylorus and therefore the natural functioning of the stomach, thus avoiding rapid emptying which is a cause of the phenomenon of dumping.
- It reduces or disappears diseases associated with obesity like hypertension, diabetes, joint disease, sleep apnea, among others.
- It allows a good quality of life.
- This is a more complex technique performed laparoscopically, so it is less used by the majority of bariatric surgeons. Only highly skilled surgeons perform the duodenal switch.
- Certain vitamins (A, D, E, K) and minerals such as iron and calcium may be absorbed poorly. This means that patients have to take supplements for life as well as perform regular blood tests.
- Symptoms such as bloating, cramping, nausea and explosive diarrhea, as well as sweating, restlessness, weakness, flushing, palpitations, and an intense desire to stretch may occur.
- Gallstone formation. Sometimes the gallbladder is removed during surgery for obesity to avoid this possibility.
