LOS Function and Obesity: The Impact of Untreated Obesity, Weight Loss, and Chronic Gastric Balloon Distension

Abstract

Impaired LOS function and increased gastro-oesophageal reflux were observed in one quarter of the untreated obese subjects. Weight loss ameliorated manometry and pH values, but subsequent balloon positioning tended to counteract these beneficial changes. In patients on balloon treatment from the start, adverse effects seemed to wear off with prolonged treatment.
