Obstructive sleep apnea (OSA) is a common sleep disorder where the airway becomes blocked during sleep, disrupting breathing. It is associated with loud snoring, daytime sleepiness, and increased risk of health conditions like diabetes, heart disease, and stroke. Left untreated, OSA can increase the risk of health complications and even sudden cardiac death. Diagnosis involves an overnight sleep study and treatment typically involves wearing a CPAP machine during sleep to keep the airway open. Adhering to CPAP therapy can significantly improve symptoms and quality of life by reducing daytime sleepiness and improving cardiovascular health.
