Sleep apnea in children: signs and when to go to the doctor

2026-05-26 12:00 Sleep

In short: Sleep apnea in children is pauses in breathing during sleep lasting more than 10 seconds. The main symptoms are loud snoring, noisy breathing, pauses in breathing, restless sleep, daytime sleepiness. If apnea is suspected, a consultation with a pediatrician is necessary.

What is sleep apnea

Apnea (from the Greek "no wind") is a temporary cessation of breathing during sleep. Short-term pauses (2-3 seconds) are the physiological norm; Pauses lasting 10 seconds or more or frequent short pauses (more than 5 times per hour) are considered pathological.

Childhood sleep apnea is different from adult sleep apnea. In children, the most common obstructive form (OSAS - obstructive sleep apnea syndrome): during sleep, the soft tissues of the throat (enlarged tonsils or adenoids) temporarily block the airways. This reduces blood oxygen saturation and disrupts sleep architecture.

How common is apnea in children

According to studies, OSAS occurs in 1-5% of children. The peak is preschool age (2-8 years), when the tonsils and adenoids are growing most actively. Boys are affected a little more often than girls. Apnea can also occur in newborns and premature babies (central apnea – associated with immaturity of the nervous system).

Signs of sleep apnea in children

Nocturnal symptoms:

Loud, constant snoring (not single snoring)
Noisy breathing, sniffling, wheezing
Visible pauses in breathing (the child "does not breathe" for a few seconds)
Restless sleep: frequent awakenings, change of position, sweating
Breathing through the mouth in a dream
Nocturnal enuresis in children over 3-4 years of age (with well-established control)

Daytime symptoms:

Daytime sleepiness, difficulty waking up
Hyperactivity, irritability, difficulty concentrating – in children, sleep deprivation is often manifested not by lethargy, but by excitement
Behavioral and learning problems
Constant breathing through the mouth and the "adenoid face"

Important: Not all children with apnea snore, and not everyone who snores has apnea. If you are worried about your child's breathing during sleep, record it on video: this is invaluable information for the doctor.

Causes of apnea in children

Enlarged adenoids and tonsils are the most common cause in children 2-8 years old
Obesity – fatty tissue in the neck narrows the airways
Anomalies of the structure of the skull and face (Down syndrome, Pierre Robin syndrome and others)
Neuromuscular diseases that reduce the tone of the muscles of the respiratory tract
Prematurity – central apnea due to immaturity of the respiratory center

Diagnosis

The standard for diagnosing apnea is polysomnography (PSG): a study of sleep in a laboratory setting that simultaneously measures breathing, blood oxygen saturation, brain activity, and other indicators. In Russia, PSG is carried out in sleep centers and some multidisciplinary hospitals.

The first step is to consult a pediatrician. He will assess the clinical picture and refer you to an otorhinolaryngologist (ENT), somnologist or pulmonologist. Important: do not try to "diagnose" apnea yourself from video - this is a clinical diagnosis.

Treatment of apnea in children

Treatment depends on the cause:

Removal of adenoids and/or tonsils (adenotonsillectomy): effective in 70% to 90% of cases in children with enlarged OSAS
CPAP therapy (continuous positive airway pressure): used for severe apnea or when surgery is contraindicated
Weight correction: for apnea due to obesity
Orthodontic treatment: for malocclusion
Observation: for mild apnea in preschoolers – the doctor may recommend observation without active treatment

Sleep Apnea and Sleep Disorders: The Connection

Sleep apnea leads to sleep fragmentation: the child wakes up frequently (not always completely), which disrupts his architecture. Chronic sleep deprivation due to sleep apnea can mimic sleep regression, frequent nighttime awakenings , and other behavioral sleep problems. It is important not to confuse these conditions: behavioral sleep problems do not require medical treatment, apnea does.

When to see a doctor

You observe pauses in the child's breathing in sleep - even once
The child snores loudly and constantly (not isolated sounds)
Noisy breathing through the mouth at night
The child, despite sufficient night sleep, constantly looks tired, hyperactive, and has difficulty concentrating
A child with Down syndrome or another systemic disease has a routine apnea examination
A premature baby in the first months of life has any pauses in breathing

Frequently Asked Questions

Is sleep apnea dangerous for a child?

Untreated severe apnea can affect cardiovascular health, cognitive development, and behavior. Timely treatment in the vast majority of cases completely eliminates the problem.

Is snoring in a child always apnea?

No. Many children periodically snore when they have a runny nose or in a certain position. Apnea is diagnosed not by snoring, but by a combination of symptoms and research data. If snoring is constant, loud and combined with other symptoms, consult a pediatrician.

Conclusion

Sleep apnea in children is a well-studied condition with clear causes and effective treatment. The main thing is to notice the symptoms in time and see a doctor, and not write it off as "just bad sleep". If something bothers you in your child's breathing, don't wait: shoot a video and show it to the pediatrician.
