What is a common complication of untreated sleep apnea?

Untreated sleep apnea can lead to several serious complications, with cardiovascular issues such as hypertension being particularly common. Sleep apnea is characterized by repeated interruptions in breathing during sleep, which deprives the body and brain of oxygen. This intermittent hypoxia can trigger a cascade of physiological responses, including increased sympathetic nervous system activity, which can elevate blood pressure. Over time, persistent hypertension can lead to more severe cardiovascular problems, including heart disease, stroke, and arrhythmias.

The relationship between sleep apnea and cardiovascular issues is well-documented, as patients with untreated sleep apnea are at increased risk for these conditions. Managing sleep apnea effectively—through methods such as continuous positive airway pressure (CPAP) therapy—can significantly reduce these risks and improve overall cardiovascular health. This underscores the importance of recognizing and treating sleep apnea to prevent its potentially life-threatening complications.
