Are you suffering from obesity and unable to lose weight with traditional methods? Bariatric surgeries can help you lose weight and prevent obesity complications. Log on to to know more about weight loss.

Biliopancreatic diversion with a duodenal switch is one of the most effective weight loss surgeries. It’s a combination of sleeve gastrectomy with an intestinal bypass. It is remarkably effective against type 2 diabetes and other obesity-related conditions. However, it is a complicated surgery that involves risks as well. Learn about biliopancreatic diversion surgery and its advantages and disadvantages in this article.  

Why is it done?  

Your doctor might recommend bariatric surgery such as a duodenal switch  

  • if you suffer from severe obesity and are on the verge of developing complications such as high blood pressure, high blood sugar, heart disease, severe sleep apnea, type 2 diabetes, stroke, and even infertility.  
  • If your BMI (Body Mass Index) is 40 or higher or if you have a BMI of 35 with one of the above mention complications.  
  • And you are not able to reduce your weight by making diet and lifestyle changes.  

Besides this, the doctor asks that you follow dietary and lifestyle changes before and after the surgery so that you can get the maximum benefits of the surgery. Because even after the surgery, if you fail to follow the dietary and lifestyle changes you can again gain weight.


Like any other surgery, a BPS/DS causes several risks to health both in the long term and short term.  

Short-term risks  

  • Excessive bleeding 
  • Blood clots 
  • Wound infection 
  • Lung or breathing problems 
  • Leaks in the gastrointestinal system 
  • Adverse reactions to anesthesia 

Long-term risks  

  • Bowel obstruction 
  • Gallstones 
  • Hernias  
  • Low blood sugar 
  • Malnutrition 
  • Dumping syndrome (causes diarrhea, nausea, or vomiting) 
  • Ulcers  
  • Stomach perforation 

However, these risks can rarely be fatal.  


  • This bariatric surgery has the highest success rate of all other bariatric surgeries with the greatest overall weight loss.  
  • Improves your hunger, metabolism, blood lipid, or blood sugar levels in the long term.  
  • Total remission of type 2 diabetes.  
  • It keeps a slightly larger gastric sleeve than other bariatric procedures which allows you to eat slightly larger meals.  
  • Very rarely causes the dumping syndrome, so you don’t need to completely avoid sugar or fats.  
  • It can increase your life significantly by reducing the risk of death by any condition.  


Before returning home, you need to stay at the hospital for a few days and then several weeks at home before you are ready to go back to work. During your recovery, you notice several changes in your body such as rapid weight loss, fatigue, hormone swings, mood shifts, nausea, hair loss, body aches, and feeling cold. 

You also need to follow strict dietary guidelines during recovery for what you should eat and how you should eat. Because your digestive system needs time to heal and adjust to recent changes. It takes one to two weeks to progress through each stage to go back to your normal diet. 

Biliopancreatic diversion with duodenal switch surgery is similar to other bariatric surgeries. However, it has the highest success rate of other surgeries and a greater amount of weight loss. But it also involves some risk of nutritional deficiencies as well. It is used for severe obesity conditions. But if you follow proper guidelines and take supplements and regular testing for life, you might have those risks and better and long-lasting results from this surgery.
