Can Sleep Apnea Be Cured By Diet and Exercise?

Weight loss helps some people with there sleep apnea it sure helps mine but loosing the weight and keeping it off
is a bit of a problem. Having said that I saw one of our members here who after losing a lot of weight had to increase
there pressure setting. I also have a female friend who after losing ~80lbs had to have another sleep study where
here pressure was changed from 12cm to 16cm so weight loss sure didn't help her. In my reading I came upon an article
that reported early brain damage may be behind a lot of sleep apnea.
