Intragastric balloon, such as the Orbera system, is a non-surgical weight loss procedure that involves placing a soft silicone balloon into the stomach to promote a feeling of fullness and reduce food intake.
Preparation: Prior to the procedure, patients may need to attend a pre-assessment appointment to evaluate their general health and discuss any medications they are taking. It's important to follow specific instructions regarding fasting before the procedure, typically refraining from food for at least 6 hours and liquids for 4 hours. Additionally, arranging for transportation home is advisable, as driving immediately after the procedure is not recommended.
Procedure: Performed under sedation or light anesthesia, the surgeon inserts a deflated silicone balloon through the mouth and into the stomach using an endoscope. Once in place, the balloon is filled with saline and a blue dye, expanding to about the size of a grapefruit. This occupies space in the stomach, leading to a sensation of fullness. The procedure typically takes around 20 to 30 minutes.
Recovery: Post-procedure, patients may experience nausea, vomiting, and abdominal discomfort for the first few days as the stomach adjusts to the balloon. A gradual reintroduction to a normal diet is recommended, starting with liquids and progressing to solid foods over several weeks. The balloon is usually left in place for up to 6 or 12 months, depending on the specific system used, after which it is removed in a similar manner to the insertion.
