Recent research underscores the prevalence of obstructive sleep apnoea in children, with delayed diagnosis risking behavioural and health complications. Experts stress the need for early detection and tailored treatments, including surgery and lifestyle interventions.
Parents may dismiss a child’s habitual snoring as harmless noise, but doctors say it can be a sign of obstructive sleep apnoea, a condition that causes repeated narrowing or blockage of the airway during sleep. The problem is not limited to adults. According to a 2024 review cited in the supplied material, estimates in pre-school children have ranged from 12.8% to 20.4%, although the true rate remains uncertain because studies have used different definitions and testing methods.
The warning signs often begin at night. Loud, regular snoring, mouth breathing, restless sleep, gasping, snorting and brief pauses in breathing can all point to a blocked airway. Mayo Clinic and MedlinePlus both note that children may also sweat at night, wake often or sleep in unusual positions. During the day, the picture can be less obvious: some children seem tired, but others become irritable, hyperactive or inattentive, with behaviour and learning problems that can resemble attention deficit hyperactivity disorder.
In younger children, enlarged tonsils and adenoids are among the most common causes. These tissues sit at the back of the throat and behind the nose, and when they are enlarged they can leave too little space for air to pass. Other risk factors include obesity, facial or jaw differences, poor muscle tone linked to conditions such as Down syndrome, and some chronic illnesses. Children’s National and Cleveland Clinic also list bedwetting, noisy breathing and difficulty waking as possible signs.
Diagnosis usually requires a sleep study, or polysomnography, which records breathing, airflow, oxygen levels, heart rate and brain activity overnight. The supplied material says a short home video may help doctors assess symptoms, but it cannot replace a formal study. In practice, a child who snores loudly most nights, gasps, or seems to struggle for breath during sleep should be assessed by a doctor, who may refer the family to a paediatrician, ear, nose and throat specialist or sleep service.
Treatment depends on the cause and severity. If enlarged tonsils or adenoids are the main problem, surgery is often the first option, and a randomised trial involving 464 children found it improved symptoms, behaviour, quality of life and sleep-study results compared with watchful waiting. However, the condition does not always disappear after surgery, particularly in children with obesity or more severe disease. Other options include treating nasal inflammation, using continuous positive airway pressure, or monitoring mild cases, though some children improve naturally as they grow.
