Bariatric surgery is associated with more robust weight loss (15–64.6%) and improvement in obstructive sleep apnea severity and gas exchange.
Bariatric surgery may be a more effective intervention for significant weight loss and improvement in respiratory function in OHS patients.

Bariatric surgery, on the other hand, is associated with more robust weight loss (15–64.6%, depending on the type of intervention), reduction of obstructive sleep apnea severity (18–44% reduction of the apnea–hypopnea index), and improvement in gas exchange (17–20% reduction in partial pressure of carbon dioxide in the arterial blood).
