Snoring may indicate the presence of a more serious health issue, and is sometimes linked to chest pain, high blood pressure, sore throat, restless sleep, and gasping or choking at night.
Lifestyle factors (i.e. alcohol consumption, being overweight) can contribute to and exacerbate snoring; however, the structural anatomy of the mouth and nasal structures must also be taken into account. Patients with a naturally elongated uvula, or with a thick, low, or soft palate are predisposed to having narrowed or obstructed airways. These patients are more likely to snore, as are patients with a deviated septum (crooked partition between the nostrils) or chronic nasal congestion. Snoring can also be linked to obstructive sleep apnea, a potentially serious medical condition.
