Obesity Surgery

Obesity Surgery

Obesity surgery also referred as Bariatric surgery or Gastric banding. This surgery is helpful in case of extreme obesity. In restrictive surgeries stomach size is shrinken by which digestion process is slowed down. Malabsorptive surgery removes part of digestive tract. An electrical device is implanted for weight loss, works by blocking signals between stomach and brain.

Bariatric surgery is a safe and effective treatment option for those affected by severe obesity. Moreover, these same procedures have also been recognized for their impact on metabolic or hormonal changes that play a major role in hunger (the desire to start eating) and satiety (the desire to stop eating) as well as improvement and/or resolution of conditions that can occur as a result of severe obesity. Bariatric surgery is a recognized and accepted approach for both weight-loss and many of the conditions that occur as a result of severe obesity; however, not all people affected by severe obesity will qualify for bariatric surgery. There are certain criteria that a person must meet in order to be a candidate for bariatric surgery.


Within two to three years after the operation, bariatric surgery usually results in a weight-loss of 10 to 35 percent of total body weight, depending on the chosen procedure. Those considering bariatric surgery should talk to their PCP about what their personal expectations should be for loss of excess weight. In addition, co-morbidities, such as diabetes, high blood pressure, sleep apnea and others are often reduced or may go into remission. Most will find they require fewer medicines throughout time and many will discontinue their medicines completely.


Research indicates that some patients who undergo bariatric surgery may have unsatisfac­tory weight-loss or regain much of the weight that they lost. Some behaviors such as frequent snacking on high-calorie foods or lack of exercise can contrib­ute to inadequate weight-loss. Technical problems that may occur after the operation, like separated stitches, may also contribute to inadequate weight-loss. There are also other potential complications that may occur which have been listed below with each of the various procedures.

Bariatric Surgery Procedures

There is a great amount of importance and responsibility associated with choosing a weight-loss treatment option. Choosing which type of bariatric surgery is right for you can be a difficult task. It is our goal to provide you with education regarding the different types of bariatric surgeries. This knowledge can assist a discussion between your physician and you in deciding the most appropriate treatment selection for you. Proper follow-up and participation in a multidisciplinary program that stresses lifestyle modification (dietary, behavioral and exercise changes) will improve the chances that a bariatric surgery patient will maximize their weight-loss and maintain it for a lifetime.

The most commonly performed bariatric surgeries include:

  • Adjustable Gastric Banding
  • Sleeve Gastrectomy
  • Roux en-Y Gastric Bypass
  • Biliopancreatic Diversion with Duodenal Switch
  • Neuromodulation

Qualifications for Sleeve Gastrectomy, Roux-en-Y Gastric Bypass and Biliopancreatic Diversion with Duodenal Switch are all the same; however, the LAP-BAND® and the VBLOC® both have different indications. The LAP-BAND® has been FDA-approved for patients with a lower BMI (BMI is at least 40 or with a BMI of at least 30 with one or more obesity-related condition), and the VBLOC® has been FDA-approved for patients with a BMI of 35-39.9 with obesity-related conditions or for people with BMI of 40-45. Please be sure to discuss the various surgical options with your physician to determine which procedure is best for you and your medical and surgical history.
