Enlarged Tonsils

Overview

Tonsils are two small pads of immune tissue at the back of the throat that help fight infection. Enlarged tonsils means they are bigger than usual. This can make the throat feel full, cause snoring or mouth breathing, and sometimes make it harder to swallow or sleep. Enlarged tonsils are not an infection by themselves; they can be caused by infections, allergies, irritation, or other factors.

Yes. Enlarged tonsils are a common reason for throat and sleep problems, especially in children. Many children have some tonsil enlargement, and most cases are mild.

It is most common in children, especially between about 3 and 10 years old, but it can affect teenagers and adults too. Children who have frequent throat infections, allergies, or exposure to smoke may be more likely to have it.

Symptoms

Common symptoms

• Sore throat or a scratchy feeling in the throat
• Snoring or noisy breathing during sleep
• Mouth breathing, especially at night
• A nasal or muffled voice
• Trouble swallowing, or a feeling that food is stuck
• Bad breath or a bad taste in the mouth
• Swollen glands in the neck
• Sleep that is not restful, or pauses in breathing during sleep

Symptoms in children

• Noisy breathing or snoring during sleep
• Pauses in breathing during sleep, or restless sleep
• Mouth breathing and drooling during sleep
• Poor appetite or slow eating
• Repeated ear infections or fluid behind the eardrum
• Being more tired or cranky than usual during the day
• Poor growth or weight gain in some children with long-term sleep problems

Symptoms in older adults

• A long-lasting sore throat or throat clearing
• Snoring or sleep that does not feel refreshing
• A feeling of a lump in the throat or trouble swallowing
• New or one-sided throat symptoms should be checked by a doctor

Causes

Main causes

• Viral infections, such as colds and flu-like illnesses
• Bacterial throat infections
• Allergies that cause ongoing swelling in the nose and throat
• Irritation from tobacco smoke or other smoke
• Acid reflux coming up from the stomach
• Long-term throat irritation, or sometimes no clear cause

Risk factors

• Being a child, especially between about 3 and 10 years old
• Frequent throat infections
• Allergies or asthma
• Exposure to second-hand smoke or living with smokers
• Acid reflux
• Family history of enlarged tonsils or tonsil surgery
• Some immune system conditions

When to see a doctor

See a doctor urgently if:

• Trouble breathing, noisy breathing at rest, or pauses in breathing during sleep
• Cannot swallow saliva, drooling, or severe trouble swallowing
• Severe one-sided throat pain or neck swelling
• High fever with a stiff neck, confusion, or feeling very unwell
• Signs of dehydration, especially in a child

Book a routine appointment if:

• Loud snoring or mouth breathing most nights
• Repeated sore throats or throat infections
• Trouble swallowing that does not settle
• A voice change that lasts more than a few weeks
• Poor sleep, daytime tiredness, or trouble at school or work
• A lump or swelling in the neck that does not go away

Diagnosis

A doctor or nurse will ask about symptoms and look inside the mouth and throat with a small light. They may feel the neck and ask about sleep, breathing, allergies, and past throat infections. They will also check for signs of infection or other causes.

Tests that may be done

• A throat swab if an infection is suspected
• Blood tests if the doctor needs more information
• A sleep study if sleep breathing problems are suspected
• Referral to an ear, nose, and throat specialist if symptoms are severe or ongoing
• Imaging tests only in unusual cases

What to expect at your appointment

The first exam is usually quick and does not hurt. Most people do not need many tests. If tests are needed, your doctor will explain why and what to expect.

Treatment

Treatment depends on the cause and how much the enlarged tonsils affect breathing, sleep, swallowing, and daily life. Mild cases may only need monitoring and self-care. If an infection, allergy, or reflux is found, treating that cause can help.

Self-care at home

• Drink plenty of fluids and eat soft foods if the throat is sore
• Get enough rest
• Use a cool-mist humidifier in the bedroom if the air is dry
• Keep away from tobacco smoke and other smoke
• Ask a pharmacist or doctor about safe pain relief for your age and health
• Saltwater gargles can help older children and adults who can gargle and spit safely
• Keep the head of the bed slightly raised for older children and adults if advised

Medical treatments

A doctor may treat an underlying cause. If a bacterial infection is confirmed, a clinician may prescribe a medicine to treat it. Allergy or reflux treatment may help if these are triggers. In some cases, a clinician may suggest a short course of medicine to reduce swelling. Do not use leftover medicines or share medicines with others. Always follow the advice of your doctor, nurse, or pharmacist.

When is surgery considered?

Surgery to remove the tonsils is called a tonsillectomy. It is considered only when enlarged tonsils cause serious problems, such as sleep breathing problems, repeated infections, trouble swallowing, or missed school or work. It is not done for mild enlargement. A specialist will discuss the risks and benefits with you.

Living with this condition

Keep an eye on sleep, breathing, and swallowing. Notice if your child snores, pauses in breathing, or seems very tired during the day. Encourage fluids and rest during flare-ups. Keep rooms smoke-free.

Lifestyle tips

• Wash hands often and teach children to do the same
• Avoid sharing cups, utensils, and toothbrushes during infections
• Keep the home and car smoke-free
• Treat allergies and reflux if a doctor finds them
• Keep routine health appointments

Diet and exercise

There is no special diet for enlarged tonsils. During a sore throat, soft cool foods and plenty of fluids can help. Regular activity is good for general health. If reflux is a trigger, avoid large meals close to bedtime and ask your doctor for advice.

Mental health and emotional wellbeing

Sleep problems and repeated illness can make children or parents feel worried, tired, or low. Children may feel anxious about sleep or missing school. If you or your child feel very distressed or unsafe, contact your local crisis service or emergency services right away.

Prevention

Enlarged tonsils cannot always be prevented, but you can lower the chance of some triggers. Reduce infections with good hand hygiene, avoid smoke, treat allergies and reflux, and keep routine vaccinations up to date.

Vaccines

There is no vaccine for enlarged tonsils. Routine vaccinations, including those offered in childhood, can reduce some infections that may lead to throat problems. Ask your local health service which vaccines are recommended for you or your child.

Screening programmes

There is no routine screening for enlarged tonsils. See a doctor if you notice ongoing snoring, mouth breathing, trouble swallowing, or sleep problems.

Complications

If left untreated

• Sleep breathing problems, including pauses in breathing during sleep
• Poor sleep, daytime tiredness, and trouble concentrating
• Slow growth or poor weight gain in some children
• Repeated throat infections
• Ear infections or fluid behind the eardrum
• A throat abscess, which is rare but serious
• Trouble swallowing or poor eating

Long-term outlook

The outlook is usually very good. Many children grow out of enlarged tonsils, and treatment can ease symptoms when they are causing problems. If surgery is needed, it is common and often helps breathing, sleep, and repeated infections. Talk with your healthcare team about the best plan for you or your child.
