Obstructive sleep apnea (OSA) is a common disorder in modern society and closely associated with obesity. Because OSA increases the likelihood of complications in the perioperative period, preoperative recognition is very important for bariatric patients. Polysomnography (PSG) remains the gold standard for diagnosis, but it is a time-consuming and expensive examination. Our study is aimed at identifying practical clinical predictors of OSA for bariatric patients. ⋯ OSA is highly prevalent (82.2%) in Asian bariatric patients. BMI, neck circumference, and scores of ESS are independent predictors of OSA in these patients.

Biliopancreatic diversion and gastric bypass are associated with a rapid improvement in insulin resistance few days after surgery. The purpose of this study was to evaluate the short-term effects in insulin resistance following sleeve gastrectomy (SG). ⋯ After SG the improvement of insulin action occurred rapidly and independently of EWL. The results of the present study confirm that a hormonal mechanism may contribute to changes in insulin resistance following SG.
