Sleep Apnea Doesn’t Only Affect Adults
Sleep apnea is often thought of as an adult condition — but it affects an estimated 1–5% of children, and rates are rising alongside childhood obesity. Pediatric sleep apnea presents differently from adult sleep apnea and, if left untreated, can have serious consequences for a child's development, behavior, academic performance, and long-term health.
Signs of Sleep Apnea in Children
Children with sleep apnea often present with symptoms that are easily confused with other conditions — particularly ADHD, behavioral problems, and learning difficulties. Watch for:
- Loud or persistent snoring — especially if it occurs most nights
- Witnessed breathing pauses during sleep
- Mouth breathing — especially during the day
- Restless sleep, unusual sleeping positions (such as neck extended or sleeping sitting up)
- Bedwetting in children who had been dry at night
- Night sweats
- Daytime behavioral problems — hyperactivity, inattention, impulsivity
- Difficulty waking up in the morning
- Poor academic performance or difficulty concentrating at school
- Growth problems — sleep apnea can interfere with growth hormone release during deep sleep
What Causes Sleep Apnea in Children?
The most common cause of sleep apnea in children is enlarged tonsils and adenoids, which can physically block the airway during sleep. This is why tonsillectomy and adenoidectomy (T&A) is the most common first-line treatment for pediatric sleep apnea — and often curative. Other causes include obesity, jaw anatomy (narrow palate, recessed jaw), Down syndrome, craniofacial abnormalities, and neuromuscular conditions affecting airway muscle tone.
How Is Pediatric Sleep Apnea Diagnosed?
Diagnosis in children typically requires an in-lab polysomnography (overnight sleep study), as home sleep tests are not validated for pediatric use. An AHI of 1 or greater is considered abnormal in children — a lower threshold than the adult standard of 5. Your child's pediatrician can refer you to a pediatric sleep specialist or ENT for evaluation.
Treatment Options for Children
Treatment depends on the cause and severity. If enlarged tonsils and adenoids are present, surgical removal is typically the first step and resolves OSA in the majority of cases. For children with anatomical jaw factors — particularly a narrow palate — palatal expansion with orthodontic appliances can widen the airway and reduce sleep apnea. CPAP is an option for children who do not respond to surgery. Dental sleep medicine appliances may be appropriate for older children and adolescents with jaw-related airway issues, in coordination with an orthodontist and sleep physician.
Why Early Treatment Matters
Untreated sleep apnea in children is not merely a sleep problem — it affects cognitive development, emotional regulation, behavior, and physical growth. Children who receive timely treatment frequently show remarkable improvements in behavior, school performance, and mood, sometimes within weeks of the airway being corrected.
