Understanding Sleep Apnea
Sleep Apnea
Sleep apnea is a sleep-related breathing disorder that repeatedly reduces or interrupts breathing during sleep. Learn about possible signs, screening, diagnostic testing and treatment pathways.
Understanding the Condition
What Is Sleep Apnea?
Sleep apnea causes repeated breathing reductions or pauses during sleep. These events can interrupt normal sleep and may affect how a person feels and functions during the day.
Repeated Breathing Changes
Breathing repeatedly becomes reduced or stops for short periods while a person sleeps.
Obstructive Sleep Apnea
The most common type occurs when the upper airway becomes partly or fully blocked during sleep.
Sleep Can Be Disrupted
Breathing events may disturb sleep even when the person does not remember waking.
Testing Is Needed
Symptoms can raise concern, but appropriate sleep testing and qualified interpretation are needed for diagnosis.
Quick answer: Snoring, fatigue or a screening result cannot confirm or rule out sleep apnea. A qualified healthcare provider uses appropriate assessment and sleep-testing results to make a diagnosis.
Recognize Possible Clues
Possible Signs and Risk Factors
Sleep apnea can affect both nighttime sleep and daytime functioning. The pattern varies, and not everyone experiences the same signs.
Possible Nighttime Signs
Loud or irregular snoring
Witnessed breathing pauses
Gasping, choking or snorting during sleep
Restless or interrupted sleep
Possible Daytime Signs
Excessive sleepiness or persistent fatigue
Morning headaches or dry mouth
Trouble concentrating or remembering
Mood changes or unrefreshing sleep
Age, body weight, family history, airway anatomy, health conditions and lifestyle factors can influence risk. No single sign or risk factor proves that sleep apnea is present.

Safety note: If you are struggling to stay awake while driving or operating equipment, stop and seek prompt medical advice.
Screening and Diagnosis
How Sleep Apnea Is Evaluated
Screening can identify possible risk. Diagnostic testing records information during sleep so a qualified provider can interpret the results and recommend next steps.
Online Screening
A questionnaire can help estimate whether certain signs and risk factors may warrant discussion with a healthcare provider. It is not a diagnosis.
Diagnostic Sleep Testing
Testing may take place at home or in a sleep laboratory, depending on symptoms, medical history and the testing pathway selected by the ordering provider.
Interpretation and Next Steps
A qualified healthcare provider reviews the available information, interprets the results and recommends any further assessment or treatment.
Important: Home sleep apnea testing is not appropriate for everyone. A negative, inconclusive or technically inadequate home test may lead to additional assessment or an in-lab sleep study.
Treatment After Diagnosis
Sleep Apnea Treatment Is Individual
Treatment depends on the type and severity of sleep apnea, symptoms, health considerations, testing results and the recommendations of the prescribing healthcare provider.
Positive Airway Pressure Therapy
CPAP, APAP or bilevel therapy may be prescribed to provide positive pressure that helps keep the airway open during sleep.
Other Treatment Pathways
Depending on the diagnosis, options may include lifestyle measures, positional strategies, oral appliances, surgery or another clinician-directed approach.

Frequently Asked Questions
Sleep Apnea FAQs
General answers about possible signs, testing and treatment pathways.
Does snoring always mean sleep apnea?
No. Snoring can occur without sleep apnea, and some people with sleep apnea may not recognize or report loud snoring. The overall symptom pattern and appropriate testing matter.
Can someone have sleep apnea without being overweight?
Yes. Body weight is one risk factor, but age, family history, airway anatomy, health conditions and other factors can also affect risk.
Can sleep apnea be tested at home?
A home sleep apnea test may be appropriate for some adults with suspected obstructive sleep apnea. It is not suitable for everyone, and the ordering provider determines the appropriate testing pathway.
Does an online screening diagnose sleep apnea?
No. Screening can estimate risk and help guide a discussion, but it cannot confirm or exclude sleep apnea. Diagnosis requires appropriate clinical assessment and diagnostic testing.
How is sleep apnea treated?
Treatment is selected after diagnosis and may include positive airway pressure therapy, an oral appliance, lifestyle measures, positional strategies, surgery or another clinician-directed approach. The appropriate option depends on the individual assessment.
