Obstructive sleep apnea remission following bariatric surgery: a national registry cohort study – “Conclusion: This study demonstrated that metabolic surgery results in OSA remission in the majority of patients with obesity.” … ” Younger age, lower BMI preprocedure, greater %EWL and the use of LSG or LRYGB positively predicted OSA remission.”

Impact of bariatric surgery on obstructive sleep apnoea–hypopnea syndrome in morbidly obese patients (National Library of Medicine) – “One of the significant observations in our study was that the improvement in OSA was evident very early after surgery much before the desired weight loss.” …

… “the magnitude of weight loss by 3 weeks would suggest weight loss alone is not a major contributor.”

Improvement in breathing biomechanics causes OSA remission and also forces posture and locomotion improvement. Improvement in posture and locomotion causes weight loss. Improvement in OSA is noticeable immediately after surgery, but the weight loss to notice takes more time.

“Few patients in our study had evidence of non-improvement or worsening of AHI despite good weight loss after surgery.” …

The reason for no remission or improvement of OSA after bariatric surgery is that there is no improvement in breathing biomechanics. In some patients of bariatric surgery, the postoperative side effects are severe, and the patient is forced to prolonged resting in, primarily by lying in bed. Weight loss due to body mass loss during prolonged bed rest is not caused by decreased food intake but by physical inactivity. Despite the weight loss, there is no improvement in breathing biomechanics.
