The impact of bariatric surgery on obstructive sleep apnea

In 2013, in a study published in Obesity Surgery Journal, there is a strong correlation between obesity and the development of OSA (surprise!).  Therefore, bariatric surgery has been touted as one of the most effective options for treating obesity and its comorbidities (like OSA).  To review whether bariatric surgery is an effective method of treatment, researchers conducted a systematic review of all the available bariatric procedures to see which procedures were the most effective in treating OSA.

The conclusion? Bariatric surgery has a profound impact on treating OSA

A total of 69 studies with 13,900 patients were included and revealed that all the procedures achieved profound effects on OSA, as over 75 % of patients saw at least an improvement in their sleep apnea.  Biliary Pancreatic Diversion (BPD) was the most successful procedure in improving or resolving OSA, with laparoscopic adjustable gastric banding being the least effective.  In other words, bariatric surgery is a definitive treatment for obstructive sleep apnea, regardless of the specific type.
