Biliopancreatic Diversion

What is a Biliopancreatic Diversion-Duodenal Switch (BPD-DS)?

A Biliopancreatic Diversion and a Biliopancreatic Diversion-Duodenal Switch are surgeries for people with severe obesity. In both procedures, a large part of your stomach is removed. Your small intestine is split into two parts. One part is attached to the reduced stomach. The other part is attached to the last part of the small intestine, close to your large intestine. This makes your digestive tract much shorter. With a BPD, you keep more of your stomach than with a BPD-DS.

The stomach reduction and intestine redirection mean that you must eat less, especially with a BPD-DS, resulting in weight loss. However, these surgeries can also have unpleasant side effects, so they are suitable only for people with severe obesity.

How does the recovery from a Biliopancreatic Diversion-Duodenal Switch proceed?

BPD and a BPD-DS are abdominal surgeries under anaesthesia. This is a big intervention for your body. Therefore, take it easy after the procedure. This is beneficial for your recovery. On average, the recovery from a BPD-DS takes 3 to 6 weeks. During this period, it is important to follow the advice of your doctor.

This timeline is an indication of recovery after a Biliopancreatic Diversion-Duodenal Switch. How long recovery takes and how it proceeds varies. Your doctor can tell you more about this.

The advantages and disadvantages of a Biliopancreatic Diversion-Duodenal Switch

You usually lose 85 % of your excess weight, which makes you feel fitter.

Problems with your blood sugar decrease or disappear.

Unpleasant consequences of your overweight decrease or disappear.

Due to the surgery, you absorb much fewer vitamins and minerals. Deficiencies can lead to problems.

Food intolerances can (temporarily) occur. Often this concerns meat, dairy, bread, and pasta.

The surgery alone is not the solution. Your healthy lifestyle, mindset and nutrition are just as important to lose weight and stay fit.

No surgery is without risk. This certainly applies to a Biliopancreatic Diversion-Duodenal Switch. Complications can occur such as wound infections, bleeding, thrombosis, hernia, gastric ulcer, intestinal leakage, vomiting, dumping syndrome, and malnutrition. Malnutrition increases the risk of death.

Why do you need extra vitamins and minerals after a Biliopancreatic Diversion-Duodenal Switch?

These surgeries reduce the intake number of vitamins and minerals. This is because your stomach is reduced and you consume less, but also because a large part of the small intestine is cut off from food, and nutrients are best absorbed here. This increases the risk of deficiencies after a Biliopancreatic Diversion-Duodenal Switch.

In addition, after your stomach reduction, you may not be able to tolerate certain foods (temporarily). This mainly applies to:

  • Meat: source of protein, vitamin B12 and iron.
  • Dairy: source of calcium.
  • Bread and pasta: source of fiber.

What happens if you don't get enough vitamins and minerals?

A vitamin or mineral deficiency doesn't show up right away. It's likely you won't notice it for a while. For example, you might sleep worse or feel more tired faster. You may also experience hair loss. After a Biliopancreatic Diversion-Duodenal Switch, you lose weight quickly, but extra vitamins and minerals are more important than ever – now and in the future. Taking a multivitamin makes this easier for you. Prevention is better than cure!
