An orally-administered device intended to facilitate weight loss and treat obesity through appetite control. It is designed to be swallowed before meals to form a viscous gel in the stomach and/or small intestine to increase distention, creating the sensation of fullness and causing the user to eat less. It may additionally slow down intestinal glucose absorption to improve glycaemic control. It typically includes natural or modified fibre which expands after absorbing water; it is available in tablet, capsule, and powder sachet forms. This is a single-use device.
