Gastric Banding Procedure is less invasive than other surgical weight loss procedures. But it’s still important to note that all surgical procedures carry risks. There are risks that come with the medications and the methods used in the surgical procedure, as well as risks that come from how your body responds to any foreign object implanted in it.

It is important to talk in detail with your surgeon about the risks and complications that might arise during a Gastric Banding Procedure.

What are the specific risks & possible complications?

Complications that have been reported after gastric restrictive procedures include:

  • Ulceration
  • Gastritis (inflammation of the stomach lining)
  • Gastro-oesophageal reflux (regurgitation)
  • Heartburn
  • Gas bloat
  • Dysphagia (difficulty swallowing)
  • Dehydration
  • Constipation
  • Weight regain.

Laparoscopic surgery has its own set of possible problems. They include:

  • Spleen or liver damage (sometimes requiring spleen removal)
  • Bleeding from major blood vessels
  • Lung problems
  • Thrombosis (blood clots)
  • Rupture of the wound
  • Perforation of the stomach during surgery
  • Mortality.

There are also problems that can occur that are directly related to the Gastric Band itself:

  • Band slippage
  • Pouch dilatation
  • Nausea and/or vomiting
  • Stoma outlet obstruction
  • Band erosion into the stomach tissue
  • Infection
  • Deflation of the band
  • Abdominal pain
  • Oesophageal distension or dilatation
  • Access port flips, leaks and infections.

Rapid weight loss may result in symptoms of malnutrition, anaemia or related complications and development of gallstones.
