Snoring can be a sign of a more serious condition called obstructive sleep apnea. That's a condition in which a person repeatedly stops breathing for brief periods of time during sleep. It may make you gasp for breath or wake you during the night. Signs of it include dry mouth, headache, or a sore throat in the morning. It's linked to stroke, high blood pressure, and heart disease, so see your doctor if you think you might have sleep apnea. They may recommend a device that helps you breathe while you sleep or, in some cases, surgery.
