Bariatric Procedures: Gastric Bypass

Tuesday, December 11, 2018

Bon Secours does a variety of safe and popular bariatric weight loss surgery procedures. One of them is the Roux-en-Y gastric bypass, often just called gastric bypass. It is the oldest weight loss surgery, having been used for decades. While it used to be an “open” operation with a large cut, it is now a laparoscopic operation with small incisions uses for better healing.

“The way the gastric bypass differs from the others, we’re not removing things like we are with the sleeve, we’re not using implanted devices like we are with the band or with the balloon, but we are giving two different ways to help a patient lose weight,” said Dr. Gregory Adams, a Bon Secours bariatric surgeon.

During a gastric bypass, a corner of the stomach is cut off from the main part of the stomach, making a pouch that is about the size of your thumb. This corner becomes the new stomach, but the rest of the stomach stays in your abdomen. The smaller stomach greatly reduces how much food you can eat at one time and changes the hormones causing hunger, decreasing the amount of hunger you feel.

Part of your intestine will then be cut and sewn to the pouch. This way food can go from the pouch directly into your small intestine, around the main part of the stomach that you’re no longer using. If you eat foods that generally cause weight gain because they are high in sugar or fat, your intestines will be irritated and you will feel temporarily unwell, reducing the temptation to eat those foods.

The gastric bypass is a safe procedure with a long track record of success. It’s the “gold standard” weight loss surgery and provides the greatest amount of weight loss for patients.

For a Roux-en-Y gastric bypass, as with all bariatric surgeries, you will have extensive guidance on what you need to eat and what you cannot eat after the surgery. Follow all directions from your care team so that you will get the correct amount of nutrients and not disrupt your healing.
