A gastric balloon is a weight loss solution that involves placing a soft, inflatable balloon in the stomach to reduce its capacity and help you feel fuller faster and stay fuller for longer. It is considered safe and a less invasive alternative to weight loss surgery. The balloon stays in the stomach for a period of time, usually several months, during which it helps you to eat smaller portions, consume fewer calories, and achieve significant weight loss. After this residence period, the balloon deflates and is removed either through endoscopy, or in the case of the Allurion Balloon, passes out of the body naturally.
