Adenoids in children

Overview

Adenoids are soft, small lumps of tissue located at the back of the nose, just behind the roof of the mouth. They are part of the immune system and help fight infections, especially in young children. Sometimes adenoids become enlarged or infected, which can cause breathing and other problems.

Yes, enlarged or infected adenoids are very common in children, especially between ages 2 and 6. Most children have adenoid tissue by birth, and it naturally shrinks as they get older.

Adenoid problems mostly affect children. They are less common in teenagers and adults because adenoids shrink with age.

Symptoms

Common symptoms

• Noisy breathing or mouth breathing
• Snoring during sleep
• Blocked or stuffy nose that does not go away
• Breathing pauses during sleep (sleep apnea)
• Frequent ear infections or hearing loss
• Sore throat or difficulty swallowing
• Voice sounding 'nasally'

Symptoms in children

• Breathing through the mouth most of the time
• Snoring loudly
• Restless sleep or waking up often
• Pauses in breathing during sleep (sleep apnea)
• Frequent colds or ear infections
• Trouble hearing or speech delays
• Drooling or difficulty swallowing

Symptoms in older adults

• Adenoids usually shrink by adulthood, so symptoms are rare. If present, they are similar to those in children but may include more ear or sinus problems.

Causes

Main causes

• Enlarged adenoids due to natural growth in young children
• Repeated infections (colds, tonsillitis) causing swelling
• Chronic sinus infections or allergies

Risk factors

• Young age (2–6 years old)
• Frequent childhood infections
• Family history of adenoid problems
• Allergies or asthma
• Exposure to secondhand smoke

When to see a doctor

See a doctor urgently if:

• Your child has difficulty breathing or pauses in breathing during sleep
• Your child has a high fever (over 38.5°C) with severe sore throat or drooling
• Your child shows signs of dehydration (dry mouth, few wet nappies, sunken eyes)

Book a routine appointment if:

• Your child snores loudly most nights
• Your child breathes through the mouth all the time
• Your child has frequent ear infections or trouble hearing
• Your child has sleep problems or seems very tired during the day

Diagnosis

A doctor will ask about your child’s symptoms and do a physical exam. They may look at the back of the nose using a small, flexible camera or use a special mirror. They may also feel the neck for swollen glands.

Tests that may be done

• Nasal endoscopy (thin tube with a camera through the nose)
• X-ray of the neck to see the size of the adenoids
• Sleep study (polysomnography) if sleep apnea is suspected
• Hearing test if ear infections or hearing loss are present

What to expect at your appointment

The doctor will first ask about your child’s symptoms, like snoring, breathing, and ear infections. Then they might look in the nose or order a simple X-ray. These tests are quick and not painful. Your child may feel a little uncomfortable during the endoscopy, but it usually takes only a few minutes.

Treatment

Many children with enlarged adenoids do not need treatment because the condition often improves on its own as they grow older. Treatment depends on how bad the symptoms are and whether there are complications (like ear infections or sleep apnea). Options include watching and waiting, medicine, or surgery.

Self-care at home

• Use a cool-mist humidifier in your child’s room to keep the air moist
• Encourage your child to drink plenty of fluids
• Use saline (saltwater) nose drops or sprays to help clear the nose
• Raise the head of your child’s bed slightly to help with breathing
• Keep your home smoke-free

Medical treatments

A doctor may recommend a nasal spray that contains a steroid to help shrink swollen adenoids. This is usually used for a few months. Antibiotics may be given for a bacterial infection if present. For children with allergies, allergy medicines like antihistamines might help. Always follow your doctor’s advice on which treatment is right for your child. Do not use over-the-counter cold medicines without checking with your doctor.

When is surgery considered?

Surgery (adenoidectomy) may be recommended if your child has very large adenoids that cause breathing problems, sleep apnea, frequent ear infections that do not improve with other treatments, or hearing loss. The operation removes the adenoid tissue and is done under general anaesthesia. Most children go home the same day and recover quickly.

Living with this condition

Most children with adenoid problems can still play, go to school, and do normal activities. If your child snores or breathes through their mouth, you can help by keeping their nose clear and using a humidifier. Make sure they get plenty of rest and drink enough fluids.

Lifestyle tips

• Keep your child away from smoke and other irritants
• Practice good hand washing to reduce infections
• Use a clean, cool-mist humidifier in the bedroom
• Encourage your child to sleep on their side or with a slightly raised head

Diet and exercise

A healthy diet with plenty of fruits and vegetables helps support the immune system. Encourage your child to be active, but if they have trouble breathing at night, they may feel tired during the day. Rest when needed. Drinking warm fluids (like soup or water) can soothe a sore throat.

Mental health and emotional wellbeing

Chronic snoring or breathing problems can affect sleep quality, which may make your child irritable, tired, or have trouble focusing during the day. This can sometimes affect mood and school performance. Let their teacher know what’s going on, and seek help from a doctor if sleep problems persist. Reassure your child that this is common and often gets better with time or treatment.

Prevention

Adenoid enlargement cannot always be prevented, especially in young children. However, you can reduce the chance of infections that cause swelling by practising good hygiene, avoiding smoke exposure, and keeping your child up to date with vaccinations.

Vaccines

Keeping your child’s vaccinations on schedule, including the pneumococcal vaccine and the flu vaccine, can help prevent some infections that may contribute to adenoid problems.

Screening programmes

There is no routine screening test for adenoid problems. If your child has symptoms like chronic snoring, mouth breathing, or frequent ear infections, see a doctor for evaluation.

Complications

If left untreated

• Obstructive sleep apnea (pauses in breathing during sleep)
• Frequent ear infections (otitis media) that can lead to hearing loss
• Speech problems (because hearing affects speech development)
• Facial changes from long-term mouth breathing (adenoid facies)
• Poor sleep quality affecting growth and learning

Long-term outlook

Most children with enlarged adenoids improve as they grow older, often by the teenage years. Even if surgery is needed, it is a safe and effective treatment, and most children recover quickly and have no lasting problems. With proper care and monitoring, the outlook is excellent.
