Many people snore occasionally. This usually is not a problem.
Snoring is caused by a blockage in the nose, mouth, or throat (upper airway).
Snoring is different from
sleep apnea, in which a person regularly stops
breathing for 10 seconds or longer, because air is still able to flow through
the passages and breathing does not stop. Snoring does not disturb the person's
sleep, and there is no decrease in the amount of oxygen going to the brain or
tissues of the body.
In adults, frequent snoring (rather than occasional snoring) has been
linked to
heart attack because of reduced blood flow in heart
(angina pectoris) and
stroke.
Although most people with sleep apnea snore, not all
people who snore have sleep apnea. Talk to your health professional if
you snore and think you might have sleep apnea.
