Primary Obesity Surgery Endolumenal (POSE)
A non-surgical, incisionless endoscopic procedure that reduces stomach capacity to help you feel full sooner.
Plain English
Patient-Friendly Explanation
POSE is a non-surgical weight loss procedure done through the mouth using an endoscope — a flexible tube with a camera. It places small folds or sutures in the stomach to reduce how much food the stomach can hold, helping you feel full sooner. There are no external cuts or scars.

Clinical Definition
Primary Obesity Surgery Endolumenal (POSE) is an incisionless endoscopic bariatric procedure that creates full-thickness plications in the gastric fundus and body to reduce gastric volume and alter gastric accommodation. The procedure is performed transorally under general anaesthesia and typically results in 15–20% total body weight loss at one year.
