What are the risks of gastric sleeve surgery?

Over time, you may have problems from poor nutrition. Some vitamin and minerals may not be well absorbed, because a large portion of your stomach has been removed. You should expect to work with your doctor over a long period of time to prevent problems.

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). Some people develop gallstones or a nutritional deficiency condition such as anemia or osteoporosis.
