Malabsorptive bariatric surgery, also known as gastric bypass surgery, is a form of weight loss surgery that alters your digestive process. Bariatric surgery can effectively treat morbid obesity in cases where you have tried diets, exercise, therapy, and medication without success.

If you have struggled with trying everything imaginable to lose weight and have not yet achieved the results you’ve been looking for, malabsorptive bariatric surgery could be for you.

How Does Bariatric Surgery Work?

Restriction

Restricts the amount of food taken in by limiting the size of the stomach.

Malabsorption

Limits the absorption of foods in the intestine by bypassing part of the small intestine to some degree.

Combination

Both of the above methods are combined in some way.


What is the Difference Between Gastric Sleeve and Gastric Bypass?

If you were to receive gastric bypass surgery, your stomach would be made smaller by closing off part of your small intestine so that food bypasses it. Gastric bypass surgery circumvents part of your digestive tract, while gastric sleeve surgery (sleeve gastrectomy) does not.

Can I Eat Foods Like Popcorn After Gastric Bypass?

While it may be tempting to go back to your normal eating habits after receiving weight loss surgery, it is best to avoid foods that have little or no nutritional value. Eating foods like pastries, candy, chips, pretzels, rice cakes, and popcorn could cause you to become malnourished or to begin regaining previously shed pounds.

What Are Some Examples of Gastric Bypass Surgeries?

In the United States, five different types of bariatric surgical procedures are generally used to obtain continued weight loss results.

Gastric banding and gastric stapling are both restrictive procedures. Biliopancreatic diversion with or without duodenal switch (BPD-DS) is mainly a malabsorptive surgery. Gastric banding is the most non-invasive weight loss surgery, as well as the safest.

Roux-en-Y Gastric Bypass (RYGBP) Surgery is the most popular bariatric procedure. The procedure works by combining both restrictive and malabsorptive aspects.

How The Restrictive Aspect of Gastric Bypass Works

The restrictive aspect of RYGBP is achieved by stapling the stomach into two separate sections. The upper section, which is a small pouch, functionally becomes the new stomach.

The size of this section is gradually reduced to limit food intake progressively. This allows you to feel satisfied and full while eating less food.

The malabsorptive aspect of gastric bypass surgery is achieved by dividing your small intestine at a specified position. This forms a shape resembling a “Y.” The lower part of your intestine is connected to the upper section of your stomach created earlier. This allows food to bypass the upper portion of the small intestine, reducing absorption.

How is RYGBP Performed?

The Roux-en-Y gastric bypass is often performed using a laparoscope rather than through an open incision. This reduces the length of your hospital stay and shortens your recovery time.


Biliopancreatic Inversion (BPD) Surgery

BPD surgery is mainly a malabsorptive surgery. It is a more complex procedure than the Roux-en-Y gastric bypass described above.

In this procedure, part of your stomach is removed. The remaining portion of your stomach is connected directly to the last part of your intestine. As your food is digested, it bypasses a larger section of your intestine than with RYGBP.

How Does BPD Surgery Compare to RYGBP Surgery?

BPD surgery results in a greater degree of malabsorption that you would experience with RYGBP. Because of this, patients who receive BPD surgery may experience some malnutrition in certain cases, which is why most patients prefer RYGBP.

Are There Other Types of BPD Surgery?

There is one other variation of BPD surgery known as the duodenal switch (BPD-DS). With this type of BPD procedure, you retain part of the stomach, which includes the valve that controls the release of food into the small intestine.

This helps to prevent the “dumping syndrome,” which can sometimes be associated with BPD. A portion of your upper intestine is also retained. These factors combine to help BPD-DS have potential advantages over BPD for some patients.
