Sleep apnea and snoring in children: when to see a doctor

When should you see a doctor about a child's snoring?

See a doctor when snoring comes back most nights for several weeks with no cold to explain it, or when it comes with breathing pauses, restless sleep or marked tiredness during the day. French health insurance (ameli.fr) also advises seeing a doctor when a child's snoring is frequent or prolonged. Snoring during a cold, on its own, does not call for a visit.

Occasional snoring, during a cold, nasal congestion, or seasonal allergies, is very common in children. It usually clears up along with its cause, within a few days, and needs nothing beyond what's already being done to relieve a stuffy nose.

Chronic snoring is recognized by how regular it is: it comes back most nights, over several weeks, regardless of any cold or allergy episode. This ongoing pattern can be linked to sleep apnea, especially when combined with other signs, which is a good reason to bring it up with a doctor.

Numbers help keep things in proportion. A Japanese questionnaire survey of 25,211 children aged 6 to 15 found that 9.5% showed signs suggestive of obstructive sleep apnea, and 1.6% had them at least five times a week. These figures come from questionnaire answers; they are not diagnoses. The American Academy of Pediatrics' literature review reports a prevalence of obstructive sleep apnea ranging from 0% to 5.7% depending on the study.

The most common causes in children

In children, the most common cause of chronic snoring is the size of the tonsils and adenoids. When they're particularly large, they narrow the airway at the back of the throat during sleep, just as the muscles relax. This is the first thing a doctor looks for during an exam.

Other factors can add to this: allergic rhinitis or chronic nasal congestion, being overweight, or certain anatomical features or medical conditions that raise the risk. None of these factors have anything to do with a mistake on the parents' part or with how the child is positioned at night.

Warning signs, beyond the snoring itself

The signs of possible sleep apnea show up both at night and during the day. At night, you may notice loud or labored breathing, visible breathing pauses followed by a gasp or louder snoring, restless sleep with frequent changes in position, and sometimes sweating.

Other signs show up more during the day: fatigue that persists despite what looks like enough sleep, trouble concentrating, unusual irritability or restlessness, and sometimes headaches on waking. It's the combination of several of these signs, both at night and during the day, that really carries weight in deciding to see a doctor, not a single isolated episode. In the Japanese survey, marked daytime sleepiness went hand in hand with loud snoring and breathing pauses.

When sleep apnea hides behind another reason for a visit

Sleep apnea can also show up through other sleep problems in children. The European Respiratory Society task force lists enuresis among the possible consequences of sleep-disordered breathing, and the International Children's Continence Society guidelines on bedwetting name loud snoring and sleep apnea among the conditions to take into account.

A review of childhood parasomnias notes that sleep apnea can make confusional arousals, sleepwalking, and night terrors more likely. When a child has episodes of night terrors or sleepwalking and also snores, it's worth mentioning both to the doctor.

How to decide, in practice: the example of a two-week log

When there are no warning signs, a two-week log helps you decide and prepare for the appointment better than listening for a single night. Take a six-year-old who has been snoring loudly since the school year started. Their parents note down, for two weeks, the nights with snoring, any pauses in breathing, how the child looks in the morning, and their mood during the day. They can also record a few minutes of the child's breathing on a phone, so the doctor can listen.

What happens next depends on that log. If the snoring only shows up during a cold and stops with it, there's nothing more to do. If it comes back most nights without a cold, mention it to the pediatrician at the next visit. If it comes with breathing pauses, very restless sleep, or marked tiredness during the day, book an appointment without waiting for the routine checkup or the end of the log. Significant difficulty breathing is no longer a matter for a scheduled visit: call emergency services.

Why see a doctor, without ever diagnosing it yourself

A clinical exam, sometimes followed by a sleep study done in a specialized setting, remains the only way to reliably tell harmless snoring apart from true sleep apnea. According to the American Academy of Pediatrics' report, most screening tests have low sensitivity and specificity. The European task force recommends measuring severity objectively, preferably with polysomnography.

Bringing it up with the pediatrician is part of entirely normal follow-up care: the American Academy of Pediatrics' guidelines specifically ask doctors to routinely ask, at every follow-up visit, whether the child snores. Depending on what they find, the pediatrician can refer the child to an ENT specialist or a sleep specialist for further steps.

What a visit to the doctor covers

The exam starts with the throat and nose, looking for enlarged tonsils or adenoids. When sleep apnea is confirmed and the exam finds this enlargement, surgical removal is the treatment most often offered first. Other options exist depending on the cause identified, which the specialist discusses case by case.

A large US trial called CHAT compared early removal of the tonsils and adenoids with watchful waiting in 464 children aged 5 to 9 without prolonged drops in blood oxygen during sleep. After seven months, sleep studies had returned to normal in 79% of the children who had surgery, versus 46% of those who were only monitored. The attention test wasn't significantly better, but symptoms, behavior, and quality of life improved more after surgery.

These results suggest that watchful waiting can be discussed, but it's the doctor who decides on it and sets up the follow-up. None of this can be decided or assessed at home: a visit is precisely what resolves the uncertainty, rather than stretching out weeks of observation without a clear answer.
