The City Hospital at White Rock bariatric surgeons on the medical staff offer My New Beginning patients a weight loss surgery option surgical procedure called gastric bypass surgery, also known as Roux-en-Y gastric bypass.

Gastric Bypass Weight Loss Surgery: The Procedure

In this weight loss surgery, procedure a portion of the stomach is closed off using a stapler device. This creates a small pouch that is then connected to the distal small intestine. During digestion, food bypasses the rest of the stomach and the upper portion of the small intestine. Food is absorbed differently because the stomach, duodenum and upper intestine no longer have as much contact with the food. Because of the new structure of the stomach, patients are not able to eat as much food. This may lead to more weight loss these patients realize after surgery.


What to Expect Before Gastric Bypass Surgery

The first step in choosing gastric bypass surgery at City Hospital at White Rock in Dallas is to come in for a one-on-one consultation. You will go over your weight loss surgery options and expectations so you can make an informed choice about your surgery. Two weeks before surgery, we suggest that all bariatric surgery patients focus on changing their diets. This will prepare your body for significant changes and make your surgery safer.


What to Expect During Gastric Bypass Surgery

First, you will receive general anesthesia before your weight loss surgery. Then, your surgeon will make tiny incisions on your abdomen to create your new stomach, which will be ¼ the size of your regular stomach.


What to Expect After Gastric Bypass Surgery

It will take some time to recover, so it’s important to rest, monitor your caloric intake and follow your doctor’s orders for diet and medicine. You won’t be able to exercise right away, but gradually it will be crucial to start an exercise program that you can follow.
