Snoring

Definition

Considerations

Snoring is common in adults and usually is not a sign of an underlying disorder.

Sometimes, however, snoring can be a sign of a serious sleep disorder called sleep apnea. This means you have periods when you are not breathing for more than 10 seconds while you sleep. During an apnea episode, there is a long period of silence just after snoring. The episode is followed by a sudden snort or gasp when breathing resumes. Then, snoring starts all over again. If you have sleep apnea, this cycle generally happens several times a night.

Risks associated with sleep apnea include stroke, irregular heart rhythms, and heart attack due to lack of oxygen. A doctor (or a sleep specialist) can tell if you have sleep apnea by doing a sleep study either at home or in a hospital setting.

Causes

In most people, the reason for snoring is not known. Some potential causes (other than sleep apnea) include:

• Being overweight, which leads to excessive neck tissue that puts pressure on the airways
• Last month of pregnancy
• Nasal congestion from colds or allergies, especially if it lasts a long time
• Swelling of the muscular part of the roof of the mouth (soft palate) or uvula, the piece of tissue that hangs down in the back of the mouth
• Swollen adenoids and tonsils that block the airways
• Using sleeping pills, antihistamines, or alcohol at bedtime

Home Care

The following can help reduce snoring:

• Lose weight if you are overweight.
• Avoid alcohol and other sedatives at bedtime.
• Try over-the-counter, drug-free nasal strips that help widen the nostrils.
• Avoid sleeping flat on your back. Sleep on your side if possible. Some doctors even suggest sewing a golf or tennis ball into the back of your night clothes. Then, if you roll over onto your back, you are reminded to stay on your side because of the discomfort. Eventually, sleeping on your side is a habit and you don't need to be reminded.

When to Contact a Medical Professional

Call your doctor right away if you awaken at night confused. Also call your doctor if you have:

• Excessive daytime drowsiness, morning headaches, recent weight gain, awakening in the morning not feeling rested, or change in your level of attention, concentration, or memory
• Episodes of no breathing (apnea) -- your partner may need to tell you if this is happening

Children with chronic snoring should also be evaluated for apnea. Sleep apnea in children has been linked to growth problems, ADHD, poor school performance, learning difficulties, bedwetting, and high blood pressure. Most children who snore do NOT have apnea, but a sleep study is the only reliable way to tell for sure.

What to Expect at Your Office Visit

Your doctor will ask questions to evaluate your snoring and perform a physical exam, paying careful attention to your throat, mouth, and neck.

Questions may include the following (some of which your partner might have to answer):

• Is your snoring loud?
• Does it occur no matter what position you are lying in or only in certain positions?
• Does your own snoring ever wake you up?
• How often do you snore? Every night?
• Is your snoring persistent during the night?
• Are there episodes when you are not breathing?
• Do you have other symptoms like daytime drowsiness, morning headaches, insomnia, or memory loss?

Referral to a sleep specialist for sleep studies may be needed.

Treatment options include:

• Dental appliances to prevent tongue from falling back
• Palatoplasty -- stiffening of the palate using surgery or injection
• Use of a CPAP mask (a device you wear on the nose while sleeping to decrease snoring and sleep apnea)
• Surgery (for example, correction of a deviated septum)
• Weight loss
