People of all ages may be at risk for sleep apnea, but there are some who have a greater risk. For example, men are typically found to suffer from sleep apnea than women, and older adults are more affected than young adults or children.
If you're obese you may be at a greater risk of the disorder as well. You can also be more inclined to suffer from this sleep disorder if you smoke, drink excessive amounts of alcohol, or have a family history of it.
