Bariatric Surgery and Death Rates

A useful study has shown that death rates are a bit higher than anticipated following bariatric surgery, and in the short commentary that was written up in JAMA about the article, it merely states that the deaths in the first few months were largely due to coronary artery disease. Yet, no mention is made about the likely contribution of untreated sleep apnea in many of these cases. Even today, it is not clear whether all bariatric centers require pre-op sleep testing in obese patients to determine whether they suffer from sleep apnea.
