What Causes People to Snore?

Weak muscles in the throat and/or enlarged tongue base

When muscles are too relaxed the tongue may fall back into the airway and pull in air from the sides of the throat. This can also happen if you are sedated by alcohol or medications.

Excessive throat tissue

Often overweight individuals have bulky neck tissue, which can cause snoring. Children with large tonsils or adenoids may also snore.

Blocked nasal airways

If the nose is blocked, it requires extra effort to pull air through. This creates a larger than normal vacuum and pulls together the floppy tissues in the throat, and the end result is snoring. In some cases snoring only takes place when you are sick with a cold or sinus infection, or during the hayfever season.
