Obesity is a disease that weight loss surgery doesn’t cure. Gastric bypass, gastric sleeve and gastric band (LAP-BAND®) procedures jumpstart weight loss, and help many patients sustain their weight loss for the long-term. However, after weight loss surgery, patients often feel invincible, and believe the disease is cured or the weight will never come back. Some let their guard down, and after a period of time find themselves regaining weight. 

For patients who have gained the weight back or who were not able to lose the amount of weight they wanted after bariatric surgery, New Jersey Bariatric Center® offers several weight loss surgery revision procedures to patients who qualify to help them reach their weight loss goals.

Revision Surgery Options

Gastric Band to Gastric Sleeve  

In some patients, the gastric band (LAP-BAND®) may fail to provide adequate weight loss and the patient may be considered for band removal and revision surgery to the gastric sleeve.  

After the band’s removal, the surgeon removes a portion of the stomach and narrows the remaining part to the size of a banana or a vertical “sleeve,” limiting food intake and reducing overall hunger. The procedure also causes the secretion of fewer hunger hormones – grehlins – resulting in less overall hunger leading to weight loss.  Visit the Gastric Sleeve page to learn more about gastric sleeve surgery.

Gastric Band to Gastric Bypass

After the removal of the band, the surgeon creates a small pouch at the top of the stomach, stapling it off from the rest of your stomach. Then the surgeon cuts the small intestine and sews part of it directly to the new pouch.  This limits food intake as well as decreases the secretion of the hunger hormones – gremlins –  and the amount of calories absorbed by the body.  This dual approach – the restrictive [restricting the amount of food) and malabsorption (reduces the amount of calories absorbed) – leads to weight loss.  To learn more, visit the Gastric Bypass page.

Gastric Sleeve to Gastric Bypass

When revising the gastric sleeve to a gastric bypass, the surgeon shortens the sleeve to create a gastric pouch, then reroutes the small intestine to the bottom of the pouch.  A smaller stomach – the gastric pouch –  leads to decreased calorie absorption, a more limited food intake and a continued lowering of hunger hormones secreted. 

Gastric Bypass Revision

The gastric bypass revision surgery involves making the gastric pouch a smaller size as well as narrowing the connection between the pouch and the small intestine. This leads to further limiting food intake. Because this procedure requires re-stapling, it may be associated with a higher complication rate.


As with any surgery, there are risks to weight loss procedures. When deciding whether revision weight loss surgery is right for you, the potential health benefits must outweigh the potential risks. Gastroesophageal reflux (GERD), leaks from staple lines, narrowing of a passage (stenosis) are possible.

*Results may vary. According to national studies, bariatric surgery results in an average weight loss of 55-80 percent of excess body weight.

Deciding if Weight Loss Revision Surgery is Right for You

Not all patients will be good candidates for revision surgery. New Jersey Bariatric Center’s® surgeons will review your case, including medical records and weight loss history, and decide together with you whether you are a candidate for a revision procedure.

In addition, most insurance companies require patients to:

  • Be at least two years out from weight loss surgery; 
  • Have lost less than 50 percent of their excess weight; or
  • Address a new health concern such as acid reflux, gastric ulcer, etc.
