A Case of Obstructive Sleep Apnea Syndrome Remarkably Improved by Gastric Restriction Surgery

Abstract

A 23-year-man with morbid obesity and obstructive sleep apnea syndrome (OSAS) was admitted. he was 170cm in height and 170kg in weight. He underwent dietary treatment several times, but his weight returned to its original level, or even higher, within a short period. A diagnosis of OSAS was made by nocturnal polysomnography.
In this morbidly obese patient with OSAS a nocturnal sleep apnea study was performed before and after weight reduction surgery (gastric restriction). The postoperative findings revealed a dramatic body weight reduction. At the same time, the results of apnea and oxygen desaturation were remarkably improved too.
These results indicate that weight reduction surgery is a definitely effective treatment for morbid obesity associated with OSAS.
