What causes snoring?
Snoring can be caused by enlarged tonsils, the nose structure or excess weight around the neck. During sleep, our neck muscles can relax so much that in some cases the throat partly closes and becomes narrow, causing the vibration sound known as snoring.

Why do people snore?
Some people snore and some don’t. Here’s why:
- People with enlarged tonsils or an enlarged tongue are more likely to snore.
- People with extra weight around the neck are more likely to snore.
- The shape of one’s nose or jaw can also cause snoring.
More than snoring: sleep apnea and fatigue
Snoring was the first sign for Leilani N. that she had obstructive sleep apnea. When her grandchildren complained about her constant snoring, she knew she needed to talk to her doctor.
