You snore. You wake up tired. Your partner says you stop breathing at night. If any of this sounds familiar, you might have sleep apnea, a condition where your breathing repeatedly stops and starts during sleep. It affects about 25% of men and 10% of women, and most people who have it don't know.
Sleep apnea means "without breath" in Greek. During an apnea episode, your airway partially or completely collapses, blocking airflow for 10-30 seconds. Your brain detects the oxygen drop and briefly wakes you up (often so briefly you don't remember). This can happen 5-30+ times per hour, preventing you from getting deep, restorative sleep.
Untreated sleep apnea is associated with serious health consequences:
The gold standard for diagnosis is a polysomnography (sleep study), either in a sleep lab or with a home sleep test. During the study, sensors monitor your breathing, oxygen levels, heart rate, brain waves, and body movements. An AHI (Apnea-Hypopnea Index) of 5-15 is mild, 15-30 is moderate, and 30+ is severe.
The most common and effective treatment. A mask worn over the nose (or nose and mouth) delivers a continuous stream of air that keeps the airway open. Compliance is the biggest challenge: many people find the mask uncomfortable. Modern machines are much quieter and more comfortable than older models.
Mandibular advancement devices (MADs) push the lower jaw forward, opening the airway. They're less effective than CPAP for moderate to severe apnea but work well for mild cases and for people who can't tolerate CPAP.
For overweight patients, losing 10-15% of body weight can reduce AHI by 50% or more. In some cases, weight loss eliminates sleep apnea entirely.
Several surgical options exist: UPPP (removing excess tissue from the throat), genioglossus advancement (repositioning the tongue muscle), or Inspire (a surgically implanted device that stimulates the hypoglossal nerve to keep the airway open during sleep).

Yes, though it's uncommon. Central sleep apnea often occurs without snoring. Some people with obstructive sleep apnea don't snore loudly but still have breathing interruptions. If you have daytime sleepiness and morning headaches without obvious snoring, ask your doctor about a sleep study.
Yes. In children, the most common cause is enlarged tonsils and adenoids, not obesity. Signs include snoring, mouth breathing, restless sleep, bedwetting, and behavioral problems. Treatment is usually tonsillectomy/adenoidectomy, which resolves the apnea in 80-90% of cases.
Genetics play a role in airway anatomy, facial structure, and fat distribution, all of which affect sleep apnea risk. If a parent or sibling has sleep apnea, your risk is 2-4x higher. But lifestyle factors (weight, alcohol use, smoking) are also significant.
While sleep apnea itself rarely causes death directly, it significantly increases the risk of fatal cardiovascular events (heart attack, stroke, arrhythmia). A study in the journal Sleep found that severe untreated sleep apnea was associated with a 30% increased risk of all-cause mortality. Treatment with CPAP eliminates this excess risk.
Many people notice improved sleep quality and daytime alertness within the first few nights. Full benefits (improved blood pressure, mood, cognitive function) typically develop over 2-3 months of consistent use. The key is using it every night for at least 4+ hours. Even partial use is better than none.
