Snoring & Sleep Apnoea in Children

Snoring in children is common, but it is not always harmless. While occasional snoring can happen during a cold or blocked nose, persistent snoring may be a sign of obstructive sleep apnoea (OSA) — a condition that affects a child’s breathing during sleep.

Understanding the causes, symptoms, and treatment options can help parents know when to seek help and what to expect next.

What Is Sleep Apnoea in Children?

Obstructive Sleep Apnoea (OSA) is a condition where a child’s airway becomes partially or completely blocked during sleep. This blockage causes repeated pauses in breathing, leading to disrupted sleep and reduced oxygen levels.

Because children are still growing and developing, untreated sleep apnoea can affect not just sleep quality, but also behaviour, learning, growth, and overall health.

What Causes Snoring and Sleep Apnoea in Children?

In children, sleep apnoea is most commonly caused by physical blockage of the airway rather than lifestyle factors.

Common causes include:

Often, more than one factor contributes to the problem.

Symptoms of Sleep Apnoea in Children

Parents may notice:

  • Loud, regular snoring
  • Pauses in breathing during sleep
  • Gasping, choking, or laboured breathing
  • Restless sleep or unusual sleeping positions
  • Mouth breathing during sleep
  • Bedwetting in older children

Unlike adults, children with sleep apnoea may not appear sleepy. Instead, they may have:

  • Poor concentration or learning difficulties
  • Hyperactivity or behavioural issues
  • Irritability or mood changes
  • Morning headaches
  • Daytime fatigue
  • Poor school performance

Why Is Sleep Apnoea a Concern?

If left untreated, childhood sleep apnoea can lead to:

  • Poor growth
  • Speech and learning difficulties
  • Behavioural and attention problems
  • Cardiovascular strain over time
  • Reduced quality of life for both child and family

Early diagnosis and treatment can prevent these long-term effects.

How Is Sleep Apnoea Diagnosed?

An ENT specialist will start with a thorough assessment of your child’s:

  • Nose
  • Tonsils and adenoids
  • Jaw and airway anatomy

If needed, a sleep study (polysomnography) may be arranged. This test monitors breathing, oxygen levels, heart rate, and sleep patterns overnight to:

  • Confirm the diagnosis
  • Determine the severity of sleep apnoea
  • Guide treatment decisions

Treatment Options for Snoring and Sleep Apnoea in Children

Treatment depends on the cause and severity of the condition.

Medical (Non-Surgical) Management

  • Treatment of nasal allergies using nasal sprays or antihistamines
  • Managing chronic nasal congestion
  • Weight management, if obesity is a contributing factor

These measures may be sufficient for mild cases or as part of a combined approach.

Surgical Treatment

Surgery is often recommended when there is a clear physical obstruction.

Common surgical options include:

  • Tonsillectomy and adenoidectomy (removal or ablation of enlarged tonsils and adenoids)
  • Reduction of enlarged nasal turbinates
  • Correction of a deviated nasal septum, if significant
  • Surgery targeting other areas of airway narrowing, depending on individual anatomy

Surgery is tailored to your child’s specific site of obstruction.

Can Snoring in Children Be Prevented?

While not all cases can be prevented, parents can help by:

  • Managing nasal allergies early
  • Avoiding exposure to cigarette smoke
  • Encouraging healthy weight habits
  • Seeking medical advice for persistent snoring

When Should Parents See a Doctor?

You should seek medical advice if your child:

  • Snores loudly most nights
  • Has pauses in breathing during sleep
  • Struggles to breathe or gasps at night
  • Shows behavioural, learning, or attention issues
  • Seems tired despite adequate sleep

Early evaluation allows for timely treatment and better long-term outcomes.
