During a temporary blockage such as a cold, snoring is to be expected. Regular snoring that goes on night after night, however, should be evaluated; in children the most common cause is enlarged adenoids and tonsils.

Signs to watch for

  • Breathing that stops for a moment during the night and then returns with a deep breath
  • Sleeping with the mouth open, lying with the neck tilted back
  • Heavy sweating, restless sleep, frequent changes of position
  • A dry mouth and headache in the morning
  • Daytime sleepiness, poor concentration, restlessness
  • A drop in school performance
  • Insufficient weight gain for age

These findings may indicate that breathing during sleep is affected, and therefore require evaluation by a doctor.

Causes

The most common are enlarged adenoids and tonsils. Allergic nasal congestion, a deviated septum, obesity and certain structural differences may also contribute.

What the assessment involves

History and examination are the first step. A short video recorded by the family at night is very helpful for the doctor. If considered necessary, an ear, nose and throat evaluation, an X-ray of the nasopharynx or a sleep study may be requested.

Why it matters

Breathing that is interrupted again and again during sleep prevents the child from reaching deep sleep. If this continues for a long time, it can affect growth, attention and behaviour.
