Bariatric Surgery Risks and Complications

What are the potential risks and complications of gastric banding surgery?

As with any surgical procedure, there are potential risks and complications that can occur in gastric banding. We're committed to providing you with the information you need to make a well-informed decision about your surgery. Although these problems rarely occur, we want you to know the facts. Risks are categorized into three areas: gastric banding risks, bariatric surgery risks, and abdominal surgery risks.

If you're considering the REALIZE^® Band, we encourage you to attend a free information seminar offered by a REALIZE Band trained surgeon. You'll learn about weight loss surgery options, including gastric banding benefits and risks, meet bariatric team members who will support you before and long after your surgery, and you may also hear from patients who have had weight loss surgery. There's no pressure to make a commitment—and no better way to get the answers you're looking for. Of course, family and friends are welcome, too.

Weight loss surgery side effects and discomfort⁸

After surgery, your body needs to adjust to the newly implanted REALIZE Band. Your recovery experience may not be the same as other patients. Regurgitation, nausea, acid reflux, constipation, and diarrhea are typical. However, if you have abdominal pain that lasts more than 3 hours, you should contact your surgeon right away or go to your local emergency room.

People who lose a lot of weight, regardless of the weight loss method, are at a high risk for developing gallstones. Surgery or other procedures may be necessary to remove the stones and/or the gallbladder. There may be other side effects that are specific to you. You should report any unusual experiences to your surgeon.
