Frequently Asked Questions
During RYGB and Lap-Band® procedures, the stomach size is reduced to limit the amount of food it can hold. As a result, you eat less food and lose weight.
During a RYGB procedure, two thirds of the stomach is bypassed by creating a small pouch with the remaining portion of the stomach. The small intestine is then attached to the pouch. The shortened intestine absorbs less food than before. As a result, you absorb less of the food you eat.
In an adjustable gastric band (also known as lap-band) procedure, the stomach is wrapped with an adjustable silicone band connected to an access port next to the abdominal wall, allowing your physician to increase or decrease the band’s tension by injecting or withdrawing saline.
In a gastric sleeve procedure, stomach volume is decreased by removing a portion of it, such that the remaining part of the stomach is left in the shape of a tube. The part of the stomach that is removed secretes the greatest amount of the hunger hormone Grehlin. By removing this part of the stomach, patients have a significant decrease in appetite, which accompanies early satiety or satisfaction from decreased stomach volume.
The gastric band and RYGB procedures may be reversed through revisional surgery if results of a prior gastric surgery are unsatisfactory or other issues suggest a reversal. Most revisional surgeries performed at Baylor Dallas are laparoscopic. When you meet with a physician on the medical staff at Baylor Dallas you will discuss options and determine the procedure that is most appropriate for you.
