Hi Anon,

Thanks for posting and welcome to EmpowHer!

Obstructive sleep apnea occurs when the muscles in the back of your throat relax too much to allow normal breathing. When the muscles relax, your airway narrows or closes as you breathe in and breathing may be inadequate for 10 to 20 seconds. This may lower the level of oxygen in your blood.

Complications may include 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 raises the risk of heart failure and stroke. The more severe the obstructive sleep apnea, the greater the risk of high blood pressure. People with obstructive sleep apnea are much more likely to develop abnormal heart rhythms such as atrial fibrillation. If there's underlying heart disease, these repeated multiple episodes of low blood oxygen (hypoxia or hypoxemia) could lead to sudden death from a cardiac event.



I hope this helps answer your question.

Best Wishes,
