Adjustable Gastric Band Surgery

Gastric Band Surgery

A silicone elastomer band is placed around the upper part of the stomach to create a small stomach pouch, which can hold a minimal amount of food.

gastric bypass band

During this procedure, a silicone elastomer band is placed around the upper part of the stomach to create a small stomach pouch, which can hold a minimal amount of food. The lower, larger part of the stomach is below the band. These two parts are connected by a narrow adjustable outlet created by the band.

Food passes through the outlet (“stoma” in medical terms) from the upper stomach pouch to the lower part more slowly, to create a feeling of fullness that lasts longer.

Even though the amount of food that can be consumed at a meal is restricted, food does pass through the digestive tract in the usual manner, so it is fully absorbed by the body.

The diameter of the band outlet can be adjusted in a physician’s office to control how much weight is lost over a given time depending on individual needs.

  • You may qualify for this surgery if you have:
  • Been severely obese for at least 5 years
  • Have a Body Mass Index (BMI) greater than 40 or are more than 100 pounds overweight

  • Have no substance abuse problems
  • Don’t suffer from psychosis, eating disorders, or uncontrolled depression
  • Have tried to lose weight without permanent success

  • Are unprepared to make lifestyle changes that will help you lose weight
  • Have medical conditions that make the risk of surgery outweigh any potential health benefits
  • Have a severe psychological disorder or abuse substances
  • Are not willing to follow our recommendations
  • Have grazing or snacking behaviors
  • Consumer high calorie foods or drinks

Statistics about success rates

  • Nearly 50% of Type 2 diabetes cases are resolved with Adjustable Gastric Band Surgery through weight loss
  • Significant improvements in overall cholesterol occur, including a boost in HDL levels
  • Over 70% of hypertension cases are resolved or improved through weight loss
  • Compliant patients lose roughly 50% of their excess weight
  • In studies involving more than 3,000 patients, excess weight loss ranged from approximately 30 to 90%, with a minimum of two-year postoperative follow-up
