What is Obstructive Sleep Apnea (OSA)?
OSA is a serious disorder. Your breathing stops due to blockage of the airflow in your sleep. This occurs multiple times at night, causing reduced airflow to your lungs, resulting in a reduction of your blood oxygen saturation. When this happens, your sleep is disrupted so you can wake up and breathe again.
What causes OSA?
Why does this happen?
People with narrow airways and fat tissue in the airway (seen in overweight and obese people) are at high risk of OSA. During sleep, the airway muscles relax and tissue of the soft palate may collapse, blocking the airway.
