While the majority of people who undergo bariatric surgery have a positive experience and notice substantial weight loss, a small percentage may require a second surgery, which is called revision bariatric surgery. Reasons you might need revision bariatric surgery include:
- You don’t lose enough weight or you regain the weight initially lost.
- You experience serious complications from the initial surgery.
- The initial surgical approach fails to work or malfunctions over time.
There are many types of bariatric surgery, and no one technique works perfectly for everyone. A surgery performed years ago may work for a time and then stop working, and devices such as lap bands and stomach staples may fail over time. Some people have complications such as severe diarrhea or nutrient malabsorption that need to be addressed. In these types of cases, revision bariatric surgery can be helpful.
