People with sleep apnea stop breathing for short periods of time while they are asleep. They usually don't wake up completely when this happens, but in the morning they feel exhausted and continue to feel sleepy during the day.
There are two types of sleep apnea. Obstructive sleep apnea is the most common and is caused when your throat muscles relax, blocking your airway. The other type, central sleep apnea, is caused when your brain doesn’t send the right signals to the muscles that control your breathing. Some people have a combination of the two types, called complex sleep apnea.
Sleep apnea is a potentially serious condition and should be treated.
Signs and Symptoms
The symptoms of sleep apnea include:
- Loud, irregular snoring, then quiet periods of at least 10 seconds when breathing stops. These episodes can happen up to 100 times each hour.
- Daytime sleepiness, always feeling tired
- Morning headaches, sore throat, dry mouth, cough
- Feeling depressed, moody, irritable
- Not being able to concentrate or remember
- Possible impotence or high blood pressure
What Causes It?
Sleep apnea can be caused by a blocked upper airway (called obstructive apnea), by your brain not signaling your lungs to breathe (central apnea), or by a combination of these two problems.
Many physical conditions, such as being overweight, or having large tonsils and adenoids, can cause sleep apnea. Sleep apnea is also linked to medical conditions, such as high blood pressure and diabetes. The typical person with sleep apnea is an overweight, middle-aged man with allergies. But apnea can happen at any age, and in women as well. Sometimes drugs, such as alcohol, sleeping pills, or heart medications, can trigger apnea. It can also be inherited.
What to Expect at Your Provider's Office
People with sleep apnea often go to the doctor because they feel tired all the time or because their partner complains about their snoring. Your health care provider will check your weight and blood pressure and ask about allergies. You may get a device to check your oxygen levels while you sleep. Your health care provider may also refer you to a sleep clinic for overnight testing. Sometimes, your doctor may request X-rays, computed tomography scans (CTs), or magnetic resonance imaging scans (MRIs) to see what may be blocking your airway.
Treatment depends on what is blocking your airway, how severe your sleep apnea is, and other conditions or medical problems you may have.
The most effective treatment is continuous positive airway pressure (CPAP). CPAP uses a machine and mask to blow air through your airway to keep it open.
Wearing some dental appliances may help by pushing the lower jaw forward, keeping the tongue from blocking the airway, or a combination of both. These may be uncomfortable until you get used to them.
In severe cases, surgery may be needed, but often sleep apnea can be managed with CPAP and lifestyle changes, like losing weight.
The following lifestyle changes may help obstructive apnea:
- Lose weight. This may cause your sleep apnea to go away entirely.
- Limit use of alcohol, antihistamines, or tranquilizers.
- Get treatment for allergies and colds or sinus problems.
- Gargle with salt water (without swallowing) to shrink your tonsils.
- Develop regular sleep habits, and make sure you get enough sleep at night.
- Sleep on your side rather than your back, or with your body elevated from the waist up. You can use foam wedges to raise your upper body. Don't use soft pillows, which tend to make apnea worse by pushing the chin toward the chest.
- Use an air humidifier at night.
- Don't smoke or expose yourself to other irritants, such as dust or perfumes.
- Raise the head of your bed by placing bricks under the headboard.
There is no drug that completely treats sleep apnea. Some of the drugs used in combination with CPAP include:
Medications used to treat central apnea:
- Clomipramine (Anafranil) -- side effects may include impotence
Medications used to treat obstructive apnea:
- Modafinil (Provigil) -- sometimes prescribed in combination with CPAP to treat excessive daytime sleepiness.
Complementary and Alternative Therapies
Alternative therapies may help treat sleep apnea caused by allergies. Homeopathy and nutrition are most likely to have a positive effect. While some manufacturers promote supplements for weight loss, none of these products have been proven to work as well as eating less and exercising more.
Nutrition and Supplements
- Diet -- Try eliminating mucus-producing foods (such as bananas) for 2 weeks, then reintroducing them to see if you notice any difference in sleepiness or other symptoms.
- To lose weight, eat lots of fresh fruits and vegetables, along with whole grains and low-fat dairy. Limit the amount of saturated fat (found in meats, butter, and processed foods) and instead use healthier fats like olive oil.
- Chromium -- Chromium or chromium picolonate is a popular supplement among bodybuilders and those trying to lose weight and build more lean muscle mass. However, results from scientific studies have been mixed, and its effects are small compared to those of exercise and a well-balanced diet. Chromium may improve blood sugar, which is also a risk factor for heart disease, especially in people with diabetes and glucose intolerance. However, you shouldn't take chromium to lower blood sugar without your doctor's supervision. In addition, large doses of chromium can cause kidney damage.
- Regular exercise will also help you lose weight. If you are not used to exercising, start slowly and build up to the goal of 30 minutes a day for at least 5 days a week. An ideal exercise program includes aerobic activity (walking, swimming, biking), strength training (lifting weights), and flexibility (stretching). If you are very obese or have other medical problems, talk to your doctor before starting a new exercise program.
Few studies have examined the effectiveness of specific homeopathic remedies, though it may be helpful as a supportive therapy. Professional homeopaths, however, may recommend one or more of the following treatments for sleep apnea based on their knowledge and clinical experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type -- your physical, emotional, and intellectual makeup. An experienced homeopath assesses all of these factors when determining the most appropriate remedy for a particular individual.
- Arsenicum album -- for respiratory disorders that worsen at night and are accompanied by fear, agitation, restlessness, weakness, and exhaustion.
- Lachesis -- for conditions that get worse while trying to sleep. This remedy is most appropriate for those who are intense, talkative, jealous, and may feel depressed (particularly in the morning). It may also help people who are frightened of going to sleep.
- Opium -- this remedy may be prescribed for individuals with sleep apnea and narcolepsy (inability to control falling asleep during the daytime). This remedy is appropriate for individuals who may be somewhat confused due to the sleep disorder.
- Sambucus -- for difficulty breathing at night. This remedy is most appropriate for individuals who may have nasal obstruction or asthma and actually jump up out of bed with a feeling of suffocation.
- Spongia -- for respiratory symptoms that are worsened by cold air and lying down. This remedy is appropriate for individuals who often feel a tightness in the chest area.
- Sulphur -- for chronic conditions accompanied by sleep disturbances and nightmares, especially if the individual also has skin rashes that become worse with heat. This remedy is most appropriate for individuals who prefer cold temperatures and strongly dislike any kind of restriction.
Some evidence suggests that a type of acupuncture called auriculotherapy acupoint pressure may help treat sleep apnea.
Sleep apnea is a serious condition that can cause fatal heart problems, so it's crucial to stick with your treatment plan. If you are using a mask and ventilator equipment, be sure to take care of them. If they are uncomfortable, talk to your doctor so they can be adjusted.
Keep in contact with your health care provider or sleep clinic to make sure your treatment is working.
If you are pregnant, you may have nasal congestion that makes you snore in a way that people with apnea do. However, this is not the same as sleep apnea. If you have apnea and become pregnant, be sure to continue your treatment so that your condition will not affect your baby.
People who have had a stroke and who have obstructive sleep apnea have a higher risk of early death.
