Lifestyle modifications also need to occur, such as smoking cessation and diet changes. After a few months, the bariatric team reviews the patient’s progress and determines if the patient is ready for weight-loss surgery.
Q: What are the various types of weight-loss surgery?
A: The three most common types of bariatric surgery are gastric bypass, gastric sleeve and laparoscopic banding. The principle behind all three surgeries is the same – limiting the amount of food a person can eat and/or decreasing the amount of calories the body is able to absorb.
Gastric bypass involves significantly reducing the size of the stomach into a small pouch that is then connected to the small intestine.
Gastric sleeve is a surgical removal of one side of the stomach, leaving a much smaller stomach, about the size and shape of a banana.
Laparoscopic banding is the surgical installation of an inflatable band around the opening of the stomach, restricting the amount of food a person can consume. The band is adjustable through a port that is placed in the abdomen. The banding procedure is reversible.
Q: How effective is weight-loss surgery?
A: It’s important to remember that surgery is not a quick fix and takes a serious commitment from the patient. With healthy eating and consistent exercise, patients can lose as much as 70 percent of their excess body weight. However, the degree of weight loss – and the maintenance of that weight loss – is not guaranteed. It is critical to maintain healthy lifestyle changes long after the procedure.
