Snoring

DEFINITION

Snoring is the hoarse or harsh sound that occurs when your breathing is partially obstructed in some way while you’re sleeping. Sometimes snoring may indicate a serious health condition. In addition, snoring can be a nuisance to your partner.

As many as half of adults snore sometimes. Snoring occurs when air flows past relaxed tissues in your throat, causing the tissues to vibrate as you breathe, which creates those irritating sounds.

Lifestyle changes, such as losing weight, avoiding alcohol close to bedtime or sleeping on your side, can help stop snoring.

In addition, medical devices and surgery are available that may reduce disruptive snoring. However, these aren’t suitable or necessary for everyone who snores.

CAUSES

Many factors, such as the anatomy of your mouth and sinuses, alcohol consumption, allergies, a cold, and your weight, can lead to snoring.

When you doze off and progress from a light sleep to a deep sleep, the muscles in the roof of your mouth (soft palate), tongue and throat relax. The tissues in your throat can relax enough that they partially block your airway and vibrate. And, the more narrowed your airway, the more forceful the airflow becomes. This causes tissue vibration to increase, which causes your snoring to grow louder.

The following conditions can affect the airway and cause snoring:

• Your mouth anatomy. Having a low, thick soft palate can narrow your airway. People who are overweight may have extra tissues in the back of their throat that may narrow their airways. Likewise, if the triangular piece of tissue hanging from the soft palate (uvula) is elongated, airflow can be obstructed and vibration increased.
• Alcohol consumption. Snoring also can be brought on by consuming too much alcohol before bedtime. Alcohol relaxes throat muscles and decreases your natural defenses against airway obstruction.
• Nasal problems. Chronic nasal congestion or a crooked partition between your nostrils (deviated nasal septum) may contribute to your snoring.
• Sleep apnea. Snoring also may be associated with obstructive sleep apnea. In this serious condition, your throat tissues partially or completely block your airway, preventing you from breathing.

Sleep apnea often is characterized by loud snoring followed by periods of silence when breathing stops or nearly stops. Eventually, this reduction or pause in breathing may signal you to wake up, and you may awaken with a loud snort or gasping sound. You may sleep lightly due to disrupted sleep. This pattern of breathing pauses may be repeated many times during the night.

People with sleep apnea usually experience periods when breathing slows or stops at least five times during every hour of sleep.

SYMPTOMS

Depending on the cause of your snoring, your symptoms may include:

• Noise during sleep
• Excessive daytime sleepiness
• Difficulty concentrating
• Sore throat
• Restless sleep
• Gasping or choking at night
• High blood pressure
• Chest pain at night

When to see a doctor

See your doctor if:

• Your snoring is so loud it’s disrupting your partner’s sleep
• You wake up choking or gasping

These may indicate your snoring is caused by a more serious condition, such as obstructive sleep apnea.

If your child snores, ask your pediatrician about it. Children can have obstructive sleep apnea too. Nose and throat problems — such as enlarged tonsils — and obesity often can narrow a child’s airway, which can lead to your child developing sleep apnea. Treating these conditions may help your child in many ways.
