Temple-led study shows weight loss may have significant impact on sleep apnea

More than just loud snoring, it can lead to high blood pressure, stroke, cardiovascular disease, and a poor quality of life. For years, doctors have told patients with sleep apnea that their best bet for alleviating it would be to lose weight, but there’s been very little research-based evidence to prove that.

Interesting Apnea Statistics
~~ Apnea in United States ~~

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.

~~ Apnea around the world ~~

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
