Overview
Obstructive sleep apnea (OSA) is a condition where a blockage or narrowing in your airway keeps air from moving through your windpipe when you’re asleep.
The blockage and lack of airflow can cause your blood oxygen levels to drop. This triggers a survival reflex in your brain that wakes you up just enough to breathe again. While that reflex is key in keeping you breathing, it also disrupts your sleep.
If you have frequent wakeups at night, you won’t feel rested in the morning. That can lead to a wide range of symptoms, many of which can affect your daytime functioning. Over time, these symptoms can lead to dangerous and sometimes life-threatening complications.
A healthcare provider can help you manage symptoms of OSA.
How common is obstructive sleep apnea?
OSA affects up to 1 billion people around the world who are between the ages of 30 and 69.
