Forty-five percent of normal adults snore at least occasionally and 25 percent are habitual snorers. Problem snoring is more frequent in males and overweight people and usually worsens with age. Snoring may be an indication of obstructed breathing and should not be taken lightly. An otolaryngologist can help you to determine where the anatomic source of your snoring may be, and offer solutions for this noisy and often embarrassing behavior.
People who snore may suffer from:
- Poor muscle tone in the tongue and throat. When muscles are too relaxed, the tongue falls backwards into the airway or the throat muscles draw in from the sides into the airway. Some relaxation is natural during deep sleep, but may become a problem if exacerbated by alcohol or drugs that cause sleepiness
- Excessive bulkiness of throat tissue. Children with large tonsils and adenoids often snore. Overweight people may have excess soft tissue in the neck that can lead to airway narrowing. Cysts or tumors are rare causes of airway narrowing.
- Long soft palate and/or uvula. A long palate narrows the opening from the nose into the throat. The excessive length of the soft palate and/or uvula acts as a noisy flutter valve during relaxed breathing.
- Obstructed nasal airways. A stuffy or blocked nose requires extra effort to pull air through it. This creates an exaggerated vacuum in the throat that pulls together the floppy tissues of the throat, and snoring results. So snoring may only occur during the hay fever season or with a cold or sinus infection. Also, deformities of the nose or nasal septum, such as a deviated septum can cause such an obstruction.
Snoring may be a sign of a more serious condition known as obstructive sleep apnea (OSA). Sleep apnea is characterized by multiple episodes of breathing pauses greater than 10 seconds at a time, due to upper airway narrowing or collapse. This results in lower amounts of oxygen in the blood, which causes the heart to work harder. It also causes disruption of the natural sleep cycle, which makes people feel poorly rested despite adequate time in bed. Apnea patients may experience 30 to 300 such events per night.
