Once you and your physician have decided on weight loss surgery, the next step is to choose the best procedure for your obesity. This is an individual decision based on many factors.
If you have a body mass index (BMI) greater than 40, you may be a candidate for the duodenal switch. Others with lower BMIs, but with obesity-related illnesses such as diabetes, may be candidates for this procedure.
Duodenal switch also may be effective for people with very high BMIs of greater than 55. A study found that the duodenal switch produced more weight loss than the Roux-en-Y gastric bypass in patients with a BMI of at least 50.
Keep in mind that this complex surgery does have more complications and may not be the right choice for certain high risk individuals, including those with heart failure and sleep apnea. Your doctor will help you decide if duodenal switch is right for you.
