Enlargement of the adenoids is caused by bacterial or viral infections entering through the nose, and is a natural immune response to prevent infection. Once the infection subsides, the adenoids typically shrink back to their normal size. However, in some children the adenoids remain swollen even after the infection has cleared. Conditions such as allergies, chronic sinusitis or recurrent colds may also contribute to persistent adenoid hypertrophy.
Adenoid hypertrophy affects the upper respiratory system, with noticeable symptoms primarily presenting at night. The two key symptoms are nasal congestion and snoring, but other symptoms may include:
Adenoid hypertrophy is a common cause of snoring in children, which can disrupt sleep quality, leading to developmental issues including attention deficit disorders. Enlarged adenoids, especially in children with small upper airways, can obstruct the airway, causing sleep apnea, oxygen deprivation, and in severe cases, life-threatening complications.
If left untreated, snoring caused by adenoid hypertrophy can slow development due to oxygen deprivation during sleep, affecting brain and nervous system function. This can result in poor academic performance, hyperactivity, and even facial structure abnormalities from habitual mouth breathing. Adenoid hypertrophy also disrupts normal sleep, leaving children with insufficient rest, which can lead to complications such as hyperactivity, delayed growth, bedwetting in older children, and, in severe cases, heart failure due to repeated oxygen deprivation during sleep.
For these reasons, if your child snores, do not dismiss it as normal. Consult a doctor promptly for diagnosis and appropriate treatment to prevent potential long-term complications.
The doctor will begin by reviewing the patient’s medical history and symptoms. If abnormalities are suspected, additional tests may be conducted, such as neck X-rays to assess the size of the adenoids and blood tests to check for infections. In severe cases, a sleep test may be recommended, which involves an overnight stay in a hospital to monitor various body functions, such as breathing, brain waves, heart rhythms, chest movement, oxygen levels and carbon dioxide levels.
Treatment varies depending on the underlying cause, as follows:
Surgery: If medication is ineffective and symptoms persist, such as snoring and frequent illnesses, adenoidectomy may be recommended.
Patients typically recover and experience significant improvement within 2–3 weeks after surgery.
Adenoid hypertrophy is common in children and often cannot be entirely prevented, but the condition typically improves or resolves as the child grows older. If parents are concerned, they should consult a doctor early when symptoms first appear. Medical advice can help effectively manage and control the condition.
Adenoid hypertrophy is frequently seen in children, often presenting with symptoms such as nasal congestion and runny nose, resembling allergies, along with snoring, the latter of which is an important warning sign. Parents should monitor their child closely and, if snoring is frequent or accompanied by sleep apnea, seek prompt medical attention to identify the cause and initiate timely treatment.
