Also called Intragastric Balloon Placement, in this procedure, a silicone balloon is placed inside the stomach and filled with 1-1.5 litres of saline water resulting in a reduction of hunger and early feeling of fullness. The balloon can be left inside for one year after which it is either removed or a new one is placed. This is not a permanent solution as removal of the balloon usually results in the appetite coming back to normal. As a result, weight is also gained again. It is usually used in individuals who have a prohibitively high risk for surgery. Once some weight is lost and the patient becomes fit for surgery, a definitive procedure is performed.
