It's a blanket term that describes a condition where your airway collapses while you sleep, but there are lots of causes. Smoking, drinking and other substances can cause your muscles to relax and bring on apnea, as can being overweight. Lots of body builders suffer from it as their necks become developed. The biggest "cause" once you remove factors like alcohol is heredity. You get the shape of your face from your parents, why not the anatomy of your airway as well?
