Revisional Bariatric Surgery

Revisional Bariatric Surgery

For many patients, weight loss surgery provides long term weight loss with improvement of health and quality of life. For some patients, however, their weight loss surgery does not always provide the desired results. For these patients, revisional bariatric surgery may be an option.

Revisional bariatric surgery is surgery performed on patients that have undergone previous weight loss surgery but have experienced one or more of the following:

  • Medical complications from the surgery
  • Insufficient weight loss
  • Weight regain after achieving weight loss goals

Unsuccessful resolution of comorbidities such as diabetes and high blood pressure for example

The Next Step

Your next step is to register to attend one of Dr. Ahmad’s next free informational seminars.

Revision weight loss surgery is not for everyone and the risks and benefits should be thoroughly discussed with your surgeon. The decision to undergo revision weight loss surgery is a major decision as it is considered a riskier surgery than first time weight loss surgery. Since every patient is unique, you will need to talk to your surgeon about options available for your particular situation based on your previous surgery and the options available for revision.
