1. High Blood Pressure
One of the health consequences of untreated sleep apnea that can have a big impact on your overall cardiovascular health is high blood pressure. If you already have high blood pressure, having sleep apnea can make it much worse. When you have sleep apnea, you will stop breathing repeatedly throughout the night. As your oxygen levels drop, it boosts your stress levels which results in elevated blood pressure. Sleep apnea treatment along with blood pressure medicines can help bring your blood pressure back down to a healthy level.
