A Woman Became Obese After a Poop Transplant

Scientists have known for a while that gut bacteria can play a profound role in the weight of mice. Now we have a case report in humans that is not entirely surprising: A woman gained 36 pounds and became obese in the 16 months after a fecal transplant.

…It’s impossible to draw conclusions from any single patient, of course, but this case is interesting against the broader context of what we know about the gut microbiota and weight. A decade of studies in mice have found that those implanted with the gut microbiota of obese humans will become obese, too, despite eating the same diet as those given the microbiota of non-obese humans. Gastric bypass surgery in mice also drastically shifts the gut microbiota, and it could be one reason for why the surgery is so effective for losing weight.

FDA Approves Implantable Vagus Nerve Disruptor For Weight Loss

The implants have been used to control certain forms of epilepsy for some time. The side effects are known, which is how the possible use for weight control was discovered.

In a bid to increase treatments for the nation’s 79 million obese adults, the Food and Drug Administration has approved U.S. marketing of an implantable device that stimulates weight loss by manipulating key appetite signals passing between the brain and the gut.

The new device is the Maestro Rechargeable System, manufactured by EnteroMedics of St. Paul, Minn. While the FDA has approved four medications for weight loss in the past 2 1/2 years, the Maestro system is the first weight loss device to be approved since 2007.

Over a year, on average, it increases the weight loss by “about 8.5%” compared to an implant which was turned off. And it worked for about half the people…  An overwhelming amount of the weight loss was attributable to factors other than the implant.
