> Expert opinion in a clinical review article from the British Medical Journal, Obstructive sleep apnoea, concluded that weight reduction programmes are not to be thought of as curative but rather as adjunctive for people with obstructive sleep apnoea syndrome (OSAS) [Greenstone and Hack, 2014].
> A meta-analysis of 5 small studies (n = 129) found a reduction in the apnoea/hypopnoea index (AHI) by –6.27 events/hour following supervised exercise training. This demonstrated a reduction in the severity of sleep apnoea (with minimal changes in body weight) with exercise [Iftikhar et al, 2014].
Below she’s fine.
I think the strong correlation of obesity with sleep apnea however should lend credence to the idea that it at least exacerbates it. But more to the point, there are conditions that are very similar to sleep apnea but are misdiagnosed as such. And these may very well be more related to weight.
I brought it up to my sleep doctor. I said I thought I had it because of my weight, he laughed at it. He said, "If you are overweight, that can exacerbate apnea, but IT ABSOLUTELY DOES NOT CAUSE IT. That's absurd."
My sleep doctor is suuuuper fit, and very lean. An avid runner. He said that he has a VERY bad case of sleep apnea. I was floored!
He said you either have it or you don't.
