Bariatric Artery Embolization for the Management of Moderate Obesity

Currently 1/3 of the world and 2/3 of the US population are overweight. Historical strategies for weight loss have consistently resulted in failure rates up to 95%. Recent research in the fields of obesity medicine and bariatrics have elucidated complex survival based mechanisms responsible for hunger and difficulty managing calorie restriction. Part of this system exists as a hunger hormone signaling pathway between the stomach and the brain mediated by cells in the stomach that produce ghrelin. Surgical transection of this area of the stomach has shown to decrease hunger and lead to weight loss. This trial is enrolling patients to undergo a percutaneous blocking of the arteries to this area of the stomach for the potential management of obesity.
