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.
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.
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
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.
Risk factors;
- Being a man. Men are more likely to snore or have sleep apnea than are women.
- Being overweight. People who are overweight or obese are more likely to snore or have obstructive sleep apnea.
- Having a narrow airway. Some people may have a long soft palate, or large tonsils or adenoids, which can narrow the airway and cause snoring.
- Drinking alcohol. Alcohol relaxes your throat muscles, increasing the risk of snoring.
- Having nasal problems. If you have a structural defect in your airway, such as a deviated septum, or your nose is chronically congested, your risk of snoring is greater.
- Having a family history of snoring or obstructive sleep apnea.
Complications;
Habitual snoring may be more than just a nuisance. Depending on the cause of your snoring, it may result in:
- Daytime sleepiness
- Frequent frustration or anger
- Difficulty concentrating
- A greater risk of high blood pressure, heart conditions and stroke
- An increased risk of behavior problems, such as aggression or learning problems, in children with obstructive sleep apnea
- An increased risk of motor vehicle accidents due to lack of sleep
To diagnose your condition,
your doctor will review your signs and symptoms, and your medical history. Your doctor will also perform a physical examination.
Your doctor may ask your partner some questions about when and how you snore to help assess the severity of the problem. If your child snores, you'll be asked about the severity of your child's snoring.
Imaging
- Your doctor may request an imaging test, such as an X-ray, a computerized tomography scan or magnetic resonance imaging, to check the structure of your airway for problems, such as a deviated septum.
Sleep study
- Depending on the severity of your snoring and other symptoms, your doctor may want to conduct a sleep study. Often, sleep studies may be done at home. However, depending upon your other medical problems and other sleep symptoms, you may need to stay overnight at a sleep center to undergo an in-depth analysis of your sleep habits by a team of specialists during a sleep study, called polysomnography.
- In polysomnography, you're connected to many devices and observed overnight. During the sleep study, your brain waves, blood oxygen level, heart rate and breathing rate, sleep stages, and eye and leg movements will be recorded during your sleep.
- If you're overweight, lose weight. People who are overweight may have extra tissues in the throat that contribute to snoring. Losing weight can help reduce snoring.
- Sleep on your side. Lying on your back allows your tongue to fall backward into your throat, narrowing your airway and partially obstructing airflow. Try sleeping on your side.
- Raise the head of your bed. Raising the head of your bed by about four inches may help.
- Nasal strips. Adhesive strips applied to your nose help many people increase the area of their nasal passage, enhancing their breathing. These strips aren't effective for people with sleep apnea, however.
- Treat nasal congestion or obstruction. Having allergies or a deviated septum can limit airflow through your nose. This forces you to breathe through your mouth, increasing the likelihood of snoring.Don't use an oral or spray decongestant for more than three days in a row for acute congestion unless directed to do so by your doctor. Long-term use of these medications can have a rebound effect and make your congestion worse. Ask your doctor about a prescription steroid spray if you have chronic congestion.
-
To correct a structural defect in your airway, such as a deviated septum, you may need surgery.
- Limit or avoid alcohol and sedatives. Avoid
drinking alcoholic beverages at least two hours before bedtime, and let
your doctor know about your snoring before taking sedatives. Sedatives and alcohol depress your central nervous system,
causing excessive relaxation of muscles, including the tissues in your
throat
Treatments and drugs;
To treat your condition, your doctor likely will first recommend lifestyle changes, such as losing weight, avoiding alcohol close to bedtime and changing sleeping positions.
If lifestyle changes don't eliminate snoring, your doctor may suggest:
-
Oral appliances.Oral appliances are form-fitting dental mouthpieces that help advance the position of your tongue and soft palate to keep your air passage open.
-
Continuous positive airway pressure (CPAP).
This approach involves wearing a pressurized mask over your nose while you sleep. The mask is attached to a small pump that forces air through your airway, which keeps it open. CPAP (SEE-pap) eliminates snoring and treats sleep apnea.
Although CPAP is the most reliable method of treating obstructive sleep apnea, and it's effective, some people find it uncomfortable or have trouble adjusting to the noise or feel of the machine. Your doctor may be able to make adjustments to the device if you're having trouble adjusting to the machine, such as adding a heated humidifier or nasal pillows, that might help make you more comfortable.
- Palatal implants;In this procedure, known as the pillar procedure, doctors inject braided strands of polyester filament into your soft palate, which stiffens it and reduces snoring. Palatal implants don't have any known serious side effects; however, the benefits and safety of the procedure are still being studied.
- Traditional surgery. In a procedure called uvulopalatopharyngoplasty (UPPP), you're given general anesthetics and your surgeon tightens and trims excess tissues from your throat — a type of face-lift for your throat. The risks of this procedure include bleeding, infection, pain and nasal congestion.
-
Laser surgery. In laser-assisted
uvulopalatopharyngoplasty (LAUPPP), an outpatient surgery for snoring,
your doctor uses a small hand-held laser beam to shorten the soft palate
and remove your uvula. Removing excess tissue enlarges your airway and
reduces vibration. You may need more than one session to get your
snoring under control.
Laser surgery and palatal implants aren't generally recommended as treatment for sleep apnea, because they haven't been proved effective for sleep apnea. Possible risks from these procedures include pain, infection, bleeding and nasal congestion.
- Radiofrequency tissue ablation (somnoplasty). In this outpatient procedure, you'll be given local anesthetic. Doctors use a low-intensity radiofrequency signal to shrink tissue in the soft palate to help reduce snoring. The effectiveness of this newer procedure needs further study. Generally, this procedure is less painful than other types of snoring surgery.
