Snoring is the harsh rattling noise made by some people when they sleep. Snoring occurs when the flow of air through the back of the mouth and nose becomes partially blocked and structures such as the tongue, soft palate (the back part of the roof of the mouth) and uvula (the tag that hangs at the back of the mouth) vibrate due to turbulent airflow.

 

Causes of snoring include: nasal polyps; a bend in the nasal septum (the partition running down the middle of the nose), large tonsils or adenoids, obesity, smoking, excess alcohol.

 

Surgical treatment of snoring can involve scarring of the soft palate or the removal of excess loose tissue in the throat or soft palate among many procedures.
