Obstructive sleep apnea

Overview

Obstructive sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleep.Several types of sleep apnea exist, but the most common type is obstructive sleep apnea, which occurs when your throat muscles intermittently relax and block your airway during sleep. The most noticeable sign of obstructive sleep apnea is snoring.Anyone can develop obstructive sleep apnea, although it most commonly affects middle-aged and older adults and people who are overweight.Obstructive sleep apnea treatment may involve using a device to keep your airway open or using a mouthpiece to thrust your jaw forward during sleep. Some people undergo a procedure to change the structure of their nose, mouth or throat.Obstructive sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. These muscles support structures including the soft palate, the uvula — a triangular piece of tissue hanging from the soft palate, the tonsils and the tongue.When the muscles relax, your airway narrows or closes as you breathe in and breathing may be inadequate for 10 to 20 seconds. This may lower the level of oxygen in your blood. Your brain senses this impaired breathing and briefly rouses you from sleep so that you can reopen your airway. This awakening is usually so brief that you don’t remember it.You can awaken with a transient shortness of breath that corrects itself quickly, within one or two deep breaths. You may make a snorting, choking or gasping sound.This pattern can repeat itself five to 30 times or more each hour, all night long. These disruptions impair your ability to reach the desired deep, restful phases of sleep, and you’ll probably feel sleepy during your waking hours.People with obstructive sleep apnea may not be aware that their sleep was interrupted. In fact, many people with this type of sleep apnea think they slept well all night.
