Snoring is caused by the partial blockage of the airway during sleep, leading to the vibration of the tissues in the throat. Factors such as nasal congestion, obesity, alcohol consumption, and sleep position can contribute to snoring. While snoring is a common symptom of sleep apnoea, not everyone who snores has sleep apnoea. If snoring is accompanied by pauses in breathing, gasping, or choking during sleep, it may indicate sleep apnoea, and a consultation with a healthcare professional is recommended.
