What is Sleep Apnea

Sleep apnea is a common sleep disorder where breathing repeatedly stops and starts during sleep, often due to a blocked or narrowed airway. The most common type, obstructive sleep apnea (OSA), occurs when throat muscles relax excessively, obstructing airflow and reducing oxygen levels in the body. This can lead to fragmented sleep and various health issues if left untreated.

How Common Is Sleep Apnea?

Sleep apnea is highly prevalent, affecting an estimated 9% to 38% of adults worldwide, with higher rates in certain populations. In the United States, about 1 in 5 adults has at least mild OSA, and 1 in 15 has moderate to severe cases. Alarmingly, 75% to 80% of cases remain undiagnosed, highlighting the need for greater screening and awareness.

Often undiagnosed, awareness saves lives

While sleep apnea can cause symptoms like loud snoring, gasping for air during sleep, excessive daytime fatigue, and morning headaches, many people dismiss these as normal. Untreated, it raises risks for serious complications, including hypertension, heart disease, stroke, diabetes, and cognitive impairments. Early diagnosis through sleep studies and treatments like CPAP machines or lifestyle changes can significantly improve quality of life and prevent long-term health issues.
