Weight-loss balloon pumps up optimism

Experts say it can aid obese patients without surgery

There’s a new weapon in the fight against obesity: balloons.

For many struggling with their weight, a new device has been approved that will give them another medical alternative to treatments such as prescription drugs and surgery.

It involves inserting a small balloon into the stomach through the mouth. The saline-filled balloon is meant to be a temporary measure to curb the appetite and help patients lose weight.

The federal Food and Drug Administration recently approved two intragastric balloons made by different companies in the space of two weeks. Both are aimed at adults with body mass indexes of 30 to 40 who couldn’t lose weight through diet and exercise.

The potential marketplace is huge. An estimated 45 million to 50 million adults have BMIs of 30 to 40, said Dr. John Morton, president of the American Society for Metabolic and Bariatric Surgery.

The arrival of weight-loss balloons reflects a broader shift in attitudes about people who struggle with their weight. For so long, overweight people have dealt with the guilt and shame of those extra pounds, in addition to health problems like diabetes. That’s why weight loss is such a big business.

But it’s a business built around self-treatment, leading to the rise of Weight Watchers and other diet companies, weight-loss supplements, health clubs and diet books. The questionable results from the commercial options have begun to change the widespread perception that obesity is simply the result of eating too much or exercising too little.

The medical community took a major step toward reducing the stigma of obesity when the American Medical Association in 2013 officially recognized it as a disease.

With that classification, the pharmaceutical and medical device industry has started investing more in possible treatments. The FDA has approved three weight-loss drugs since 2012. Apollo Endosurgery and ReShape Medical submitted balloons for FDA review last year.

There is a lot of enthusiasm about the balloons among some gastroenterologists because using them is less invasive than weight-loss surgery like gastric bypass. The patient is under mild sedation and the balloon is placed without surgery through a tube inserted in the mouth. The balloon should be removed after six months.

Dr. Rami Lutfi at Presence St. Joseph Hospital in Chicago will be the first physician in the Midwest to offer Apollo Endosurgery’s balloon, Orbera. The company paid for him to be trained on how to insert and remove the balloon and how to provide the necessary follow-up care.

“People still fear surgery,” Lutfi said. “The advantage of the balloon is there’s no cutting.”

But just because there’s no cutting and stitching doesn’t mean the balloon is risk-free. Patients can suffer severe nausea and vomiting in the first days after placement. Other potential risks include ulcers and balloon deflation.

In clinical data cited by the FDA in its Orbera approval, patients lost an average of 21.8 pounds (10.2 percent of their body weight) after six months, better than the 7-pound loss in patients who only tried diet and exercise. Some patients gained some weight after the device was removed but maintained an average of 19.4 pounds of weight loss nine months after placement.

The ReShape balloon, shaped like a dumbbell, is intended for adults who also have an obesity-related condition like diabetes, high blood pressure or high cholesterol. Patients with the device lost an average of 14.3 pounds in a study.

The Orbera procedure, including a 12-month diet and exercise program, will be $6,000 to $8,000, said Dennis McWilliams, founder of Apollo Endosurgery. And at least initially, he doesn’t expect insurance to cover the cost.

McWilliams said Orbera has a track record of safety overseas. The device has been used in more than 200,000 patients in about 80 countries, he said.
