Snoring occurs when the airway partially narrows during sleep, causing throat tissues to vibrate and produce sound. Sleep apnea occurs when the airway collapses completely, causing breathing to stop repeatedly through the night. While snoring is often harmless, sleep apnea is a serious medical condition linked to heart disease, stroke, diabetes, and cognitive decline. Dr. Dixit Kumar Thakur at Pulmovista Clinics accurately diagnoses which condition you are dealing with through a thorough consultation and sleep study.
