We offer minimally-invasive weight-loss procedures for people with obesity who are not candidates for traditional bariatric surgery. Our team of weight management and obesity specialists includes gastroenterologists, registered dietitians, and nurses who will work with you to develop a personalized plan to help you achieve long-term weight loss. Determine if you may be a candidate for bariatric endoscopy.

Bariatric endoscopic procedures are incisionless and can be reversed if necessary. They also do not disqualify you from a future bariatric surgery if one is needed to help you reach your weight-loss and lifestyle goals.

Types of Bariatric Endoscopic Procedures

We offer two minimally invasive, FDA-approved endoscopic weight loss procedures: intragastric balloon and endoscopic sleeve gastroplasty. We also offer endoscopic revisions to previous bariatric surgeries. 

Learn more below about what to expect from each procedure.

Intragastric Balloon (Gastric Balloon)

During intragastric balloon implantation, we will pass a deflated latex-free silicone balloon through your mouth and esophagus and into your stomach.

The balloon will then be filled with saline to take up space in your stomach and make you feel full. It will remain in your stomach for up to six months before it is deflated and removed.

When combined with lifestyle changes, including regular exercise and improved diet, the intragastric balloon can help you lose up to 25 percent of your body weight. Weight loss from intragastric balloon implantation may help improve your cholesterol, lower your blood pressure, and control diabetes and sleep apnea.

Endoscopic Sleeve Gastroplasty

During endoscopic sleeve gastroplasty, we will pass a device through your mouth and esophagus to stitch your stomach to about 33 percent of its original size. The limited stomach capacity will help you feel fuller more quickly when eating, reducing your caloric intake and aiding in weight loss.

Endoscopic sleeve gastroplasty can lead to significant weight loss, but how much you lose depends on your commitment to changing your diet and exercise habits. Weight loss as a result of endoscopic sleeve gastroplasty can improve medical conditions, including sleep apnea, diabetes, and high blood pressure.

Endoscopic Revision

Individuals who have had a previous bariatric surgery and need a corrective revision may be eligible for the revision to be performed using an endoscopic approach.  This would involve the doctor using a device to go through your mouth to perform the surgery without any incisions.

Revision procedures are based on the needs of the patient and are very individualized.
