Obstructive sleep apnoea is often thought of as an adult condition, but children can develop it too, and the warning signs are easy to miss. A child who snores loudly every night, breathes through their mouth, or shows pauses followed by gasps may be experiencing repeated airway blockages that disturb sleep and affect daytime life.
Recognising the Signs
Habitual loud snoring is the most noticeable clue, yet it is not definitive on its own. Parents should also watch for mouth breathing, restless sleep, episodes where breathing stops and then restarts with a snort or gasp, and visible effort from the chest and abdomen as the youngster struggles to draw air. Not every child who snores has sleep apnoea, but these patterns merit closer attention.
Daytime Impacts and Misdiagnosis
When sleep is repeatedly disrupted, the effects can show up in behaviour and learning rather than obvious tiredness. Some children become irritable or unusually active, find it hard to concentrate, and display difficulties that resemble or worsen attention deficit hyperactivity disorder (ADHD). Because the symptoms overlap, clinicians must be careful not to treat the situation as a simple either‑or diagnosis; the two conditions can coexist and compound each other.
Underlying Causes and Risk Factors
In younger children, enlarged tonsils and adenoids are a frequent culprit, as the narrow airway leaves little room for air to pass when the tissue swells. Obesity, variations in skull or jaw shape, and allergic rhinitis – inflammation inside the nose triggered by allergies – also raise the risk. Research has linked the condition to asthma, premature birth, and, most strikingly, Down syndrome, which carries a much higher prevalence. A 2024 systematic review of 30 studies reported preschool‑age prevalence ranging from 12.8 % to 20.4 %, though definitions and testing methods varied widely, and only two population studies used a full overnight sleep study, leaving the true figure uncertain. Separate data show that obesity among five‑ to 19‑year‑olds climbed from roughly 2 % in 1990 to about 8 % in 2022, a trend that likely contributes to rising apnoea rates. Observational studies have hinted at a role for air pollution, but the evidence remains inconclusive and should be interpreted with caution.
When to Seek Help
If a child regularly snores loudly, shows pauses or gasps, breathes through the mouth, or appears to struggle for breath during sleep, a medical assessment is warranted. A general practitioner can refer the youngster to a paediatrician, a sleep service, or an ear, nose and throat specialist for further evaluation, which may include an overnight sleep study to confirm the diagnosis.
Why it Matters
Untreated childhood sleep apnoea does more than disturb a night’s rest; it is linked to poorer behaviour, reduced learning ability, and a lower overall quality of life. Emerging research also points to impacts on blood‑pressure control and metabolic functions, including blood‑sugar regulation, which could set the stage for longer‑term health challenges. Recognising the subtle signs early and seeking appropriate care can change a child’s developmental trajectory, helping them thrive both at home and in the classroom.
