Who gets obstructive sleep apnea?

OSA can occur at any age, including children. However, it most commonly develops in middle aged men who are overweight or obese. It is thought that as many as 2 in 100 middle aged men and 1 in 100 middle aged women develop OSA.
Factors that increase the risk of developing OSA, or can make it worse, include the following. They all increase the tendency of the narrowing in the throat at night to be worse than normal.
• Overweight and obesity. Particularly if you have a thick neck as the extra fat in the neck can squash the airway.
• Drinking alcohol in the evening. Alcohol relaxes muscles more than usual and makes the brain less responsive an apnea episode. This may lead to more severe apnea episodes in people who may otherwise have mild OSA.
• Enlarged tonsils.
• Taking sedative drugs.
• Sleeping on your back rather than on your side.
