Snoring is a sound made during sleep. It is the sound of the throat vibrating as air flows through it.
Air should be able to move easily through your mouth, nose, and throat. Sometimes, during sleep, air cannot move through these areas easily. This turbulent airflow makes the roof of the mouth vibrate. This is what causes the snoring sound. Smaller airways can lead to louder snoring. Airflow may be obstructed by:
Being over 50 years old and male increase the risk of snoring. Other factors include:
The main symptom of snoring is noisy breathing during sleep.
Snoring may be associated with a sleep condition called sleep apnea. Snoring with sleep apnea may cause these symptoms:
If your snoring is severe, the doctor will want to make sure you do not have obstructive sleep apnea. Diagnosis may involve:
In cases of snoring without sleep apnea, lifestyle changes may alleviate symptoms. More severe cases may require surgery or devices.
Changes that may help stop snoring include:
Surgery may be done to remove excess tissue in the nose or throat. During surgery, a laser or scalpel will remove the tissue that is blocking the airway. Treatment by laser surgery requires a series of surgeries. These surgeries are usually reserved for severe and disruptive cases of snoring.
Another procedure is to try to stiffen the roof of the mouth.
