Sleep Apnea Causes
When you go to sleep, the muscles at the back of your throat relax. When this happens, your airway can narrow or close as you breathe. Because your airway is partly blocked, snoring results. If the airway becomes completely blocked, you can’t get any air into your lungs.
This can happen many times a night without you being aware of it. You may think you slept all night. But obstructive sleep apnea causes poor quality sleep and often results in sleepiness during the day.¹ Your brain responds to the low oxygen level in your blood by briefly waking you from sleep so that you can take a breath. Your partner may notice that you make a gasping or choking sound.¹
You can find out if you have sleep apnea, by having a sleep assessment:
*Central sleep apnea is a less common form of sleep apnea. It is caused by the brain failing to send the right signals to the muscles that control breathing. Some people have ‘complex’ sleep apnea, which is a combination of obstructive and central sleep apnea. A sleep assessment will determine whether you have these conditions.4
