Obstructive Sleep Apneas

Paediatric obstructive sleep apnoea (OSA) is a condition where a child's breathing repeatedly stops and starts during sleep, due to narrowing or blockage of the airway. It is more common than many parents realise, and can affect children of any age. Dr Harvey Kok provides specialist diagnosis and management of paediatric OSA, drawing on his dedicated training in sleep medicine.

What causes OSA in children?

In children, OSA is most commonly caused by enlarged tonsils and adenoids, which narrow the airway during sleep. Other contributing factors can include allergies and nasal congestion, obesity, and certain craniofacial or neuromuscular conditions.

Signs to look out for

  • Loud or frequent snoring

  • Pauses in breathing, gasping, or choking sounds during sleep

  • Restless sleep or unusual sleeping positions

  • Mouth breathing during the day or night

  • Difficulty waking, or excessive daytime sleepiness

  • Behavioural changes, irritability, or difficulty concentrating at school

  • Bedwetting beyond the age it would usually be expected to resolve

Diagnosis

A detailed history and examination are the starting point, often followed by a sleep study (polysomnography) to confirm the diagnosis and assess its severity. This test measures breathing patterns, oxygen levels and sleep quality overnight, and provides important information to guide treatment.

Treatment options

Treatment depends on the underlying cause and severity, and may include:

  • Referral for removal of the tonsils and adenoids, where these are the primary cause

  • Management of allergies or nasal congestion contributing to airway narrowing

  • Weight management support, where relevant

  • Continuous positive airway pressure (CPAP) therapy, in select cases

  • Ongoing monitoring and follow-up sleep studies to assess treatment response

Why treatment matters

Left untreated, OSA can affect a child's growth, behaviour, learning, and cardiovascular health over time. Early diagnosis and appropriate treatment can lead to significant improvements in sleep quality and daytime functioning.

Next steps - Schedule a consultation
