Laparoscopic Gastric Bypass

What is Gastric Bypass Surgery?

The gastric bypass surgery, also called the Roux-en-Y gastric bypass or Roux-en-Y gastric exclusion procedure, is the most commonly-performed weight loss surgery in the United States. The gastric bypass works by:

  • reducing the stomach size (satisfied with less food)
  • decreasing hunger hormones (less hunger and interest in food)
  • bypassing part of the small intestine (less absorption of calories)
  • causing dumping syndrome (so that foods high in added sugar and fat are not well-tolerated, leading to behavior modification)

The surgery also has an immediate effect on the hormones that control insulin secretion and other metabolic responses. In fact, recent studies have found that the gastric bypass surgery works better than medication for type 2 diabetes.

Gastric Bypass Surgery — A Long, Successful History

Gastric bypass surgery has been performed for more than 30 years. And Barix Clinics has been performing the surgery for the last 20 years—much longer than almost anyone. Of the three main weight loss surgery procedures (gastric bypass, gastric sleeve and adjustable gastric band), the gastric bypass has the largest amount of historical and statistical data demonstrating its effectiveness at both total weight loss and long-term success in keeping weight off.


“I am over two years out of surgery and have lost a whole adult person off of my 4'9" frame. All of my physical restrictions have been lifted. All of my co-mobidities have been cured. The last one, sleep apnea, just recently resolved itself!" Jenise M.

The gastric bypass procedure promotes a typical weight loss of 65% of excess body weight in the first year and 80% of excess weight lost by the second year. And unlike diet programs, this weight loss can be maintained long-term.  People may choose gastric bypass surgery over other types of weight loss surgery if they are looking for a faster and more complete weight loss, have type 2 diabetes or other obesity-related conditions, and want help controlling food choices (large amounts of added fat and sugar cause dumping syndrome).  Candidates for gastric bypass surgery at Barix Clinics are at least 18 years of age, have a body mass index or BMI of 35 or more (use the BMI calculator at right to find your BMI), have at least one health condition associated with obesity, and have tried more conservative weight loss methods including diet, exercise and weight loss medications. A BMI of at least 40 (or 100 lbs overweight) without obesity-related conditions also meets the qualifications for surgery.

Laparoscopic Gastric Bypass Surgery

In the gastric bypass procedure, a small (30 cc) pouch—about the size of a golf ball is created, resulting in the major portion of the stomach being bypassed. This small pouch resticts the amount of food eaten at one time reducing calorie intake.

Malabsoption of calories also promotes weight loss and is obtained by the reconfiguration of the small intestine. One end is connected to the newly created pouch and the other joins up with the intestine leaving the large stomach. This results food passing through a shorter length of the small intestine and fewer calories being absorbed.

Consuming foods high in fat and sugar result in discomfort as they pass out of the pouch and into the small intestine. Many view this effect, dumping syndrome, as an advantage of the gastic bypass surgery because of the behavior modification it promotes.

Gastric bypass surgery is most commonly performed as a laparoscopic procedure. Laparoscopic surgery patients experience significantly less pain and the recovery time is usually much faster, enabling patients to return to work weeks earlier.

Gastric bypass surgery is a safe and effective procedure when performed by specially-trained and experienced surgeons. A laparoscopic gastric bypass procedure requires a highly-skilled surgeon who not only has performed a significant number of laparoscopic bariatric procedures but also performs a large number of procedures each month.
