Risks common to all surgeries for weight loss include an infection in the incision, a leak from the stomach into the abdominal cavity (resulting in an infection called peritonitis), and a blood clot in the lung (pulmonary embolism). About one-third of all people having surgery for obesity develop gallstones or a nutritional deficiency condition such as anemia or osteoporosis. Fewer than 3 in 200 people (1.5%) die after surgery for weight loss.

Laparoscopic surgeries
The most common problems and complication after lap banding surgery include:
  • Nausea and vomiting. These can often be reduced by adjusting the tighness of the LAP BAND.
  • Complications of laparoscopic gastric banding include inability to eat (food intolerance), wound infections, band slippage, pouch enlargement, minor bleeding, and the adjusment device. Second operations may be necessary.
  • Minor surgical complication occur less than 10% of the time. These include problems with the adjusment device, wound infections, or minor bleeding.
  • The risk of death due to lap banding surgery is about 1 in 2,000.

Stomach stapling (vertical banded gastroplasty)
After stomach stapling (vertical banded gastroplasty):
  • About 1 out 5 people may need a second operation because the connection between the stomach and the intestines narrows (stomach stenosis), leading to nausea and vomiting, or because of an increase of gastroesophageal reflux after eating.
  • The staples pull loose in about 1 out of 3 cases.
  • The plastic band may slip or wear away.
