What is Malabsorptive Bariatric Surgery?

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 these methods are combined in some way.

All bariatric surgery procedures will limit the size of the stomach. However, only some will involve altering the intestines. If the surgery is malabsorptive, you will have a smaller stomach as well as a bypass in the digestion process. Therefore, all malabsorptive surgeries are considered to be combined surgeries.


What is the Difference Between Gastric Sleeve and Gastric Bypass?

Healthy lifestyle concept with diet and fitness

A vertical sleeve gastrectomy involves removing part of the stomach to reduce its capacity. However, it does not involve rerouting the intestines to alter the digestion process.

A gastric bypass surgery involves limiting the stomach and rerouting the intestines. As you digest food, the gastric juices will bypass part of the intestines, therefore getting the name “gastric bypass”. This will allow you to absorb fewer calories and nutrients from the food you are able to eat. Because you absorb less calories, this is considered a malabsorptive bariatric surgery.

What Are Some Examples of Gastric Bypass Surgeries?

We use two different types of malabsorptive bariatric surgery in our office.

Biliopancreatic diversion, sometimes with a duodenal switch (BPD-DS), removes a large portion of the stomach. The small pouch that remains is connected to the small intestine.

Roux-en-Y Gastric Bypass (RYGBP) surgery is the most popular bariatric procedure. The procedure works by reducing the size of the stomach and rerouting the digestive process.

How Bariatric Surgery 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 bariatric 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 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.
