Obstructive Sleep Apnea in Children: A Parent's Guide

Snoring vs. sleep apnea: what's the difference?

Snoring happens when air moves past relaxed tissues in the nose and throat, making them vibrate. Occasional snoring — for example, when your child has a cold or stuffy nose — is very common and usually nothing to worry about. Doctors use the term 'habitual snoring' for snoring that happens on most nights. Most children who snore have what is called primary snoring, meaning they snore but breathe normally and sleep well.

Obstructive sleep apnea is different. In OSA, the airway narrows or closes over and over during sleep, so your child briefly stops breathing or has to work hard to get air in. The brain nudges the body just enough to reopen the airway, again and again through the night, which fragments sleep even if your child never seems to fully wake up. The tricky part is that you cannot reliably tell primary snoring from OSA by the sound alone. That is why pediatric guidelines recommend that clinicians ask about snoring at every child's routine checkups, and that a child who snores regularly be evaluated further — for example, with a sleep study — when additional warning signs are present.

Why tonsils and adenoids matter

In otherwise healthy children, the most common cause of OSA is enlarged tonsils and adenoids — pads of infection-fighting tissue at the back of the throat and nose. These tissues are naturally largest, relative to the size of the small airway, during the preschool and early school-age years, which is why OSA often shows up in children roughly between ages 2 and 8. When they are big enough to crowd the airway, they can block airflow during the deep muscle relaxation of sleep.

Tonsils and adenoids are not the only cause, however. Several other factors can raise a child's risk of sleep apnea:

• Being overweight or having obesity, an increasingly common contributor as children get older
• Allergies or chronic nasal congestion that keep the nose blocked
• Down syndrome and certain differences in the structure of the face, jaw, or airway
• Conditions that lower muscle tone, such as some neuromuscular disorders
• A family history of obstructive sleep apnea

Signs to watch for at night and during the day

Because sleep apnea happens while your child is asleep, the clues can be easy to miss. Nighttime signs are often what parents notice first:

• Loud snoring on most nights, sometimes with snorts, gasps, or pauses in breathing
• Restless or sweaty sleep, or sleeping in unusual positions with the neck stretched back
• Mouth breathing and a persistently dry mouth
• New or returning bedwetting after your child had been dry at night

Daytime signs can be less obvious, and in children they often look different than in adults. Rather than appearing sleepy, many children with OSA seem wired or irritable. Watch for:

• Trouble paying attention, hyperactivity, or behavior that can look like ADHD
• Crankiness, mood swings, or new difficulties at school
• Morning headaches or a hard time waking up
• Daytime sleepiness, which is more common in older or heavier children

How sleep apnea is diagnosed

Evaluation starts with a conversation and an exam. Your pediatrician will ask about snoring, breathing pauses, and daytime behavior, and will look at your child's tonsils, nose, and jaw. It often helps to record a short video of your child sleeping and snoring on your phone to show the doctor.

When OSA is suspected, the most accurate test is an overnight sleep study, called polysomnography. Usually done in a sleep lab, it measures breathing, oxygen levels, heart rate, and sleep stages while your child sleeps, and it shows whether breathing pauses are happening and how severe they are. The at-home sleep tests marketed for adults are not considered reliable for young children. Depending on the findings and local wait times, your pediatrician may refer you to a sleep specialist or an ear, nose, and throat (ENT) surgeon.

Treatment options

The right treatment depends on the cause and how severe the apnea is. Options your child's care team may consider include:

• Surgery to remove the tonsils and adenoids (adenotonsillectomy). For many children with enlarged tonsils and adenoids, this is the first-line treatment and often improves or resolves symptoms.
• Watchful waiting. Mild OSA sometimes improves on its own as a child grows, so the doctor may recommend monitoring with a follow-up visit.
• CPAP therapy. A CPAP machine gently blows air through a mask to keep the airway open; it is used for children who are not good candidates for surgery or who still have OSA afterward.
• Treating allergies and nasal congestion. Prescription nasal sprays or other medicines can reduce swelling in milder cases; your clinician or pharmacist will determine which medicine and dose are appropriate.
• Weight management, when excess weight is a factor, as part of a gradual, family-based approach to healthy habits.
• Orthodontic or dental treatments in selected children whose jaw or palate shape narrows the airway.

One prescription medicine sometimes used for mild sleep apnea, montelukast, carries an FDA warning about possible mood and behavior changes, so it is a choice to weigh carefully with your doctor. Never give your child any medication for sleep apnea without medical guidance, and ask your clinician or pharmacist about the correct product and dose.

Why treating sleep apnea matters

Left untreated, OSA can affect more than just sleep. Over time, poor-quality sleep can contribute to attention and learning difficulties, behavior problems, bedwetting, and slower growth; severe, long-standing cases can occasionally strain the heart, though that is uncommon. The reassuring news is that childhood sleep apnea is very treatable. Once breathing improves, many parents notice better sleep and calmer days, and some children make gains at school over the following weeks to months, though results vary from child to child. If you are unsure whether your child's snoring is a problem, it is always reasonable to raise it at the next visit.

When to call your doctor

See your pediatrician if your child snores loudly on most nights, or if you notice pauses in breathing, gasping or choking, or hard work to breathe during sleep, restless sleep with bedwetting, or new daytime attention and behavior problems. Seek emergency care right away if your child struggles to breathe while awake, turns blue or gray around the lips, or is very difficult to wake.
