Sleep Apnea: Should I Have a Sleep Study?

You may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them.

Sleep Apnea: Should I Have a Sleep Study?

Get the facts

Your options

  • Have a sleep study.
  • Don't have a sleep study. Instead, use lifestyle changes to try to improve sleep.

Key points to remember

  • If you snore but don't have other symptoms of sleep apnea, you may not need a sleep study. Lifestyle changes may reduce your snoring. Examples of changes you can try are losing weight (if needed), avoiding alcohol and sedating medicines before going to bed, and sleeping on your side.
  • A sleep study is the only sure way to find out if you have sleep apnea. If you have symptoms of sleep apnea, including being very tired and sleepy during the day, your doctor will probably suggest a polysomnography sleep study.
  • You may want to know if you have sleep apnea, because it has been linked with other health problems including high blood pressure, stroke, diabetes, heart failure, and depression. It also can lead to car accidents.
  • If you know that you have sleep apnea, you can treat it.
FAQs

What is sleep apnea?

You have sleep apnea when your breathing is often blocked or partly blocked while you sleep. It can be mild, moderate, or severe, depending on the number of times an hour that you have less airflow to your lungs. For adults, apnea may occur from 5 times an hour to more than 30 times an hour.

The most common form of sleep apnea is obstructive sleep apnea. Although doctors use sleep studies to diagnose both obstructive sleep apnea and central sleep apnea, this Decision Point focuses on obstructive sleep apnea.

Obstructive sleep apnea happens when the airways in your nose, mouth, or throat are blocked or become narrow. Everyone's throat muscles and tongue relax during sleep. But in some people, certain things can cause this normal process to partly or completely block the airway.

What are the symptoms of sleep apnea?

Symptoms of sleep apnea can include:

  • Being so sleepy during the day that it gets in the way of the normal things you do, such as work or school.
  • Feeling tired in the morning.
  • Having trouble concentrating.
  • Waking up with a headache.

Your bed partner may notice that while you sleep:

  • You stop breathing.
  • You often snore loudly.
  • You gasp or choke.
  • You toss and turn.

Snoring and lack of sleep from apnea can make it hard to get through the day. You may feel grouchy a lot and have trouble focusing on work and activities. If you snore, your bed partner also might not get enough sleep. This can make your relationship suffer.

Why have a sleep study?

A sleep study is the only sure way to know if you have sleep apnea. The main type is an all-night sleep study done in a qualified sleep lab. It is called polysomnography (say "pawl-ee-sawm-NAW-gruh-fee"). Sleep studies also can be done with portable equipment that you use at home.

You might want a sleep study, because if you have sleep apnea and it's not found and treated, it can interfere with your quality of life. It can make you too sleepy when you should be awake.

It also is linked to problems such as:

  • High blood pressure.
  • High blood pressure in the lungs (pulmonary hypertension).
  • Depression.
  • Irregular heart rhythms.
  • Heart failure.
  • Coronary artery disease.
  • Stroke.

If you snore but don't have other symptoms, you may not need a sleep study. Lifestyle changes—such as losing weight (if needed) and sleeping on your side—may reduce your snoring.

How is sleep apnea treated?

Treatment for sleep apnea can include:

  • Lifestyle changes, such as losing weight (if needed), sleeping on your side, avoiding alcohol and sedating medicines before bedtime, and not smoking.
  • Continuous positive airway pressure (CPAP). This uses a machine to keep your airway open while you sleep.
  • Oral breathing devices or other types of devices that you wear while you sleep to help keep your airway open.
  • Surgery to open your airway.

Your doctor probably will have you try lifestyle changes and CPAP first. But surgery might be your first choice if your sleep apnea is caused by a blockage that can be fixed easily.

Will treating sleep apnea help?

Sleep apnea can make it hard for you to get good rest. It can make you tired during the day, and it can cause serious health problems. But treatment, like lifestyle changes, breathing machines, or oral or nasal breathing devices, can help. Breathing better at night can help you feel better during the day.

Why might your doctor recommend a sleep study?

Your doctor might recommend a sleep study if:

  • You have symptoms of sleep apnea, such as heavy snoring and being sleepy during the day.
  • You have a risk of other health problems from sleep apnea.
  • Lack of sleep is hurting your quality of life or raising safety issues.

  • You won't have the cost of testing.
  • You won't have to spend a night in a sleep lab.
  • You can decide to have a sleep study later if lifestyle changes don't reduce your symptoms.

Personal stories about sleep studies

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

My husband snores so much when he sleeps that he has been keeping me awake. I don't think that he has been sleeping well either, because sometimes he falls asleep when he is just talking to me. I discussed it with him, and we decided that he should have a sleep study to see if he has sleep apnea.

Margaret, age 47

Sometimes I snore so loudly that I wake myself from sleep. I am also tired during the day. I read somewhere that snoring could be a symptom of sleep apnea. I called my doctor and told her about my symptoms. She gave me a few tips to prevent snoring. I am going to try these methods first to see if they work before I think about having a sleep study to diagnose sleep apnea.

Jamal, age 37

I have been a truck driver for almost 20 years. Recently, I have almost had a few driving accidents because I have a hard time staying awake while driving. When I sleep at home, my wife says that I stop breathing while I sleep. I am going to have a sleep study to see if I have sleep apnea.

Hal, age 41

My partner says that sometimes I stop breathing while I am sleeping. Fortunately, I don't feel sleepy during the day. I talked with my doctor about my breathing problems because I think that I might have sleep apnea. She told me that it is common for older adults to have short lapses in breathing and that I probably don't need to have a sleep study to diagnose sleep apnea unless I am having other problems.

Frank, age 63
