Obstructive sleep apnea (OSA) is a disorder in which your breathing is repeatedly obstructed or restricted fully or partially for periods of 10 seconds or longer while you sleep. Although millions of people have sleep apnea, most don’t know it because the symptoms happen while they’re sleeping.
Obstructive sleep apnea occurs when the brain sends the signal to the muscles and the muscles make an effort to take a breath, but they are unsuccessful because the airway is blocked and prevents a good flow of air.
Sometimes the bed partner or a family member of a person with sleep apnea will tell them that they snore. While snoring is a good indicator of obstructive sleep apnea, there are other symptoms they should also be aware of.
