Obstructive sleep apnea is the most common sleep-related breathing disorder. It causes you to repeatedly stop and start breathing while you sleep.

There are several types of sleep apnea, but the most common is obstructive sleep apnea. This type of apnea occurs when your throat muscles intermittently relax and block your airway during sleep. A noticeable sign of obstructive sleep apnea is snoring.

Symptoms
Signs and symptoms of obstructive sleep apnea include:

Excessive daytime sleepiness
Loud snoring
Observed episodes of stopped breathing during sleep
Abrupt awakenings accompanied by gasping or choking
Awakening with a dry mouth or sore throat
Morning headache
Difficulty concentrating during the day
Mood changes, such as depression or irritability
High blood pressure
Decreased libido

Causes
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 back of the roof of your mouth (soft palate), the triangular piece of tissue hanging from the soft palate (uvula), the tonsils and the tongue.

When the muscles relax, your airway narrows or closes as you breathe in, hampering your breathing for 10 seconds or longer. This can lower the level of oxygen in your blood and cause a buildup of carbon dioxide.

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 shortness of breath that corrects itself quickly, within one or two deep breaths. You might 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 deep, restful phases of sleep, and you'll probably feel sleepy during your waking hours.

People with obstructive sleep apnea might not be aware of their interrupted sleep. Many people with this type of sleep apnea don't realize they haven't slept well all night.

Risk factors
Anyone can develop obstructive sleep apnea. However, certain factors put you at increased risk, including:

Excess weight. Most but not all people with obstructive sleep apnea are overweight. Fat deposits around the upper airway can obstruct breathing. Medical conditions that are associated with obesity, such as hypothyroidism and polycystic ovary syndrome, also can cause obstructive sleep apnea.
Older age. The risk of obstructive sleep apnea increases as you age but appears to level off after your 60s and 70s.
Narrowed airway. You might inherit naturally narrow airways. Or your tonsils or adenoids might become enlarged and block your airway.
High blood pressure (hypertension). Obstructive sleep apnea is relatively common in people with hypertension.
Chronic nasal congestion. Obstructive sleep apnea occurs twice as often in those who have consistent nasal congestion at night, regardless of the cause. This may be due to narrowed airways.
Smoking. People who smoke are more likely to have obstructive sleep apnea.
Diabetes. Obstructive sleep apnea might be more common in people with diabetes.
Sex. In general, men are twice or three times as likely as premenopausal women to have obstructive sleep apnea. The frequency of obstructive sleep apnea increases in women after menopause.
A family history of sleep apnea. Having family members with obstructive sleep apnea might increase your risk.
Asthma. Research has found an association between asthma and the risk of obstructive sleep apnea.
Complications
Obstructive sleep apnea is considered a serious medical condition. Complications can include:

Daytime fatigue and sleepiness. Because of a lack of restorative sleep at night, people with obstructive sleep apnea often have severe daytime drowsiness, fatigue and irritability. They might have difficulty concentrating and find themselves falling asleep at work, while watching TV or even when driving. This can put them at higher risk of work-related accidents.

Children and young people with obstructive sleep apnea might do poorly in school and commonly have attention or behavior problems.

Cardiovascular problems. Sudden drops in blood oxygen levels that occur during obstructive sleep apnea increase blood pressure and strain the cardiovascular system. Many people with obstructive sleep apnea develop high blood pressure (hypertension), which can increase the risk of heart disease.

The more severe the obstructive sleep apnea, the greater the risk of coronary artery disease, heart attacks, heart failure and strokes.

Obstructive sleep apnea increases the risk of abnormal heart rhythms (arrhythmias), which can lower blood pressure. If there's underlying heart disease, these repeated multiple episodes of arrhythmias could lead to sudden death.
