Quick Answer: Pediatric OSA at a Glance

Obstructive sleep apnea in children is brief pauses in breathing during sleep caused by an airway blockage, most common between 2 and 6 years old. [1] Signs include snoring, mouth breathing and restless sleep, plus daytime fatigue and poor focus. [1] Enlarged tonsils or adenoids are a main cause. [1] [3] Treatments include tonsil and adenoid surgery, medicines, lifestyle changes and CPAP. [1]

What the research says

• Removing tonsils and adenoids helped children with snoring and mild sleep apnea in several ways, but not on every measure. In a randomized trial of 459 children aged 3 to 12.9 with snoring and mild breathing problems during sleep, early adenotonsillectomy did not significantly improve executive function or attention at 12 months compared with watchful waiting. It did improve behavior, sleepiness, symptoms, and quality of life, and lowered blood pressure. Progression to more frequent breathing events happened in 1.3% of the surgery group versus 13.2% of the watchful waiting group. Six children (2.7%) had a serious adverse event linked to surgery. (Redline et al., JAMA, 2023) [2]

• Medicines may help some children, but the evidence is limited. A Cochrane review of 5 trials with 240 children aged 1 to 18 who had mild to moderate OSA found insufficient evidence that nasal steroids work. Montelukast, an allergy and asthma medicine, lowered the number of breathing events per hour compared with placebo. Side effects were rare and minor, and follow-up lasted only 6 weeks to 4 months. (Kuhle et al., Cochrane Database Syst Rev, 2020) [3]

What Is Childhood Obstructive Sleep Apnea?

Childhood sleep apnea (also called pediatric sleep apnea) is a condition in which there are brief pauses in a child’s breathing during sleep. [1] The most common type is obstructive sleep apnea, which happens when a blockage in the airway interferes with normal breathing. [1]

When the brain senses changes in air intake, it signals the lungs to breathe. [1] This can wake a child many times during the night, a bit like hearing a phone ring once while you sleep. The wake-ups are brief, but they disrupt sleep and can leave a child tired and moody during the day. [1]

Two rarer types exist. Central sleep apnea usually affects newborns and happens when the brain has trouble communicating with the breathing muscles. [1] Complex (mixed) sleep apnea can appear when a child with OSA starts CPAP treatment. [1]

What are the signs and symptoms of obstructive sleep apnea in children?

Parents are often the first to notice. Signs show up both at night and during the day.

Nighttime symptoms

• Loud or mouth breathing and snoring. [1]

• Pauses in breathing, sometimes with coughing or choking. [1]

• Restless sleep: tossing and turning. [1]

• Other signs: night sweats, sleepwalking or sleep talking, and bedwetting. [1]

Daytime symptoms

• Fatigue. [1]

• Inattentiveness or lack of focus. [1]

• Irritable mood, aggressiveness, or other emotional or behavioral problems. [1]

• Morning headaches. [1]

What causes obstructive sleep apnea in children and who is at risk?

Obstructive sleep apnea (OSA) in children is caused by an airway blockage, which can come from enlarged tonsils or adenoids, muscle tone changes or bone structure differences. [1] The blockage can come from:

• Enlarged tonsils or adenoids: These glands at the back of the throat can grow bigger with infection or inflammation, and some children inherit larger glands. [1]

• Muscle tone changes: Conditions such as Down syndrome or cerebral palsy can lower muscle tone in the head and neck at night, letting tissue close in on the airway. [1]

• Bone structure differences: A narrow facial structure, small jaw, or overbite can limit air intake. [1]

• A growth in the airway: This is very rare. [1]

Who is at higher risk?

Risk factor	Notes
Obesity	Having obesity raises the risk of OSA. [1]
Allergies, asthma, or upper respiratory infections	These conditions are linked to a higher risk. [1]
Tobacco smoke	Exposure to tobacco smoke raises the risk. [1]
Family history	A record of sleep apnea in the biological family suggests a genetic predisposition. [1]
Other conditions	Cleft palate or pharyngeal flap surgery, and acid reflux, are also risk factors. [1]

How Is It Diagnosed?

Obstructive sleep apnea in children is diagnosed through questions about symptoms and sleep, a physical exam and a full medical history, sometimes with referral to a sleep specialist. [1] They may refer you to a sleep specialist, who may use:

Tool	What it does
Sleep history	A report of your child’s nightly sleeping patterns. [1]
Upper airway evaluation	A physical exam, and sometimes an X-ray or a nasal scope, to look for a blockage. [1]
Sleep study (polysomnography)	Monitors your child overnight, measuring brain activity, heart rate, airflow, oxygen and carbon dioxide levels, muscle activity, chest and belly movement, and sleep interruptions. [1]

How Is It Treated?

Treatment depends on the cause and severity. [1] The goal is to clear the airway so your child can breathe normally during sleep. [1]

• Surgery: Removing enlarged tonsils (tonsillectomy) or adenoids (adenoidectomy) effectively treats the condition in many children. [1] [3] Surgery may also repair structural problems of the head and neck. [1]

• Medicines: Allergy medicines such as antihistamines, nasal fluticasone, or montelukast may help keep airways open, depending on the cause. [1] A nasal decongestant can help during an upper respiratory infection. [1] Ask your provider which, if any, fits your child.

• Lifestyle changes: Regular exercise, and diet changes that help your child reach or keep a healthy BMI for their age. [1]

• CPAP: A mask over the nose, attached to a small machine, blows air gently into the airway to keep it open during sleep. [1] If complex sleep apnea develops, a provider can adjust the pressure or refit the mask. [1]

What is the outlook for pediatric obstructive sleep apnea, and can it be prevented?

With treatment, symptoms can go away and usually will not have a long-term effect as your child grows. [1] Children with mild symptoms may grow out of it as the tissue at the back of the throat shrinks and the airway opens. [1] Symptoms can come back if a new blockage develops, and some children need long-term management into adulthood. [1]

Most causes cannot be prevented. [1] You can lower your child’s risk by encouraging regular exercise, avoiding places with tobacco smoke, and managing seasonal allergies. [1]

When should you see a healthcare provider about your child's obstructive sleep apnea?

See a provider if you notice signs of sleep apnea, especially if your child wakes often at night or has pauses in breathing while asleep. [1] Go to the ER or call your local emergency number if your child has trouble breathing, or if their skin, lips, or nails turn pale, blue, or gray. [1]

What is the bottom line on obstructive sleep apnea in children?

Obstructive sleep apnea in children is common and treatable. [1] Spotting the signs early and working with a healthcare provider helps your child get the deep, restful sleep needed for healthy growth, learning, and mood.

Does your child snore loudly or seem tired all day? Talk to your pediatrician about whether a sleep evaluation makes sense. Noting snoring, breathing pauses, and daytime behavior for a week or two can help the visit.

Frequently Asked Questions

Is snoring always a sign of sleep apnea in kids?

Not always. But loud, frequent snoring together with mouth breathing, breathing pauses, or choking is a good reason to talk to your child’s provider.

Can untreated sleep apnea cause ADHD?

Untreated childhood sleep apnea is listed as being linked to ADHD, [1] and daytime inattentiveness and irritability can look similar. A provider can help work out what is going on.

At what age is OSA most common in children?

OSA in children is most common between ages 2 and 6. [1]

Will my child outgrow sleep apnea?

Children with mild symptoms may grow out of it as the tissue at the back of the throat shrinks with age. [1] Get an evaluation first, because untreated sleep apnea can affect growth and development. [1]

What is a polysomnography?

A polysomnography is an overnight sleep study that monitors brain activity, heart rate, airflow, oxygen and carbon dioxide levels, muscle activity, and breathing movements. [1]

Can allergies make sleep apnea more likely?

Yes. Allergies are a risk factor, and managing them, including with allergy medicines, can be part of treatment. [1]

Is surgery the only way to treat pediatric OSA?

No. Depending on the cause, treatment can also include medicines, lifestyle changes, and CPAP. [1]

How does obesity affect sleep apnea in children?

Obesity is a risk factor. Diet changes and regular exercise that help a child reach or keep a healthy BMI can be part of treatment. [1]

What are adenoids?

Adenoids are glands at the back of the throat. They can become enlarged with infection or inflammation, or because of a genetic trait, and block the airway. [1]

Can bedwetting be a sign of sleep apnea?

Yes. Bedwetting is listed as a possible nighttime symptom, and loss of bladder control is a possible complication of untreated sleep apnea. [1]

What is CPAP?

CPAP stands for continuous positive airway pressure. A mask over the nose is attached to a small machine that blows air into the airway to keep it open during sleep. [1]

Can secondhand smoke increase the risk of sleep apnea?

Exposure to tobacco smoke is a risk factor. [1] Keep your child away from places where people smoke.

Are morning headaches common with OSA?

Morning headaches are one of the daytime clues listed for childhood sleep apnea, along with fatigue, lack of focus, and irritability. [1]

Can a small jaw cause sleep apnea?

Yes. A narrow facial structure, small jaw, or overbite can affect a child’s air intake. [1]

What should I do if I think my child has OSA?

Visit your child’s healthcare provider, who may recommend a sleep study or a visit with a sleep specialist. [1]
