Enlarged tonsils are tonsils that are larger than usual and may sometimes cause symptoms such as snoring, difficulty swallowing or problems breathing during sleep. The tonsils are two small areas of tissue at the back of your throat that form part of your immune system. They can become enlarged during infections, but some people naturally have larger tonsils without having an underlying health problem.

Key takeaways:
- Enlarged tonsils can develop during infections or remain large after an infection has passed.
- Treatment depends on the cause and whether the enlargement affects breathing, swallowing or sleep.
- Persistent asymmetry, worsening symptoms or breathing difficulties should be medically assessed.
What causes enlarged tonsils?
The main causes of enlarged tonsils include viral infections, bacterial infections, repeated tonsillitis and naturally large tonsils.
Tonsils often swell when your immune system responds to an infection. This swelling may occur alongside a sore throat, fever, swollen neck glands and discomfort when swallowing. The enlargement usually improves as the infection settles.
Repeated episodes of tonsillitis can cause recurring swelling and discomfort. Sometimes, the tonsils remain relatively large even after the infection has cleared.
Children commonly have larger tonsils than adults, but enlarged tonsils can also affect adults. In some cases, the enlargement can narrow the airway during sleep, contributing to snoring or obstructive sleep apnoea.
Less commonly, one tonsil may be noticeably larger than the other because of a local infection or another underlying condition. Persistent or unexplained enlargement, particularly when accompanied by a neck lump, should be assessed by a healthcare professional.
How do you treat enlarged tonsils?
The treatment for enlarged tonsils depends on what is causing them and whether they are affecting breathing, swallowing or everyday activities.
If the enlargement is caused by a viral infection, treatment usually involves rest, fluids and suitable pain relief while the infection improves. Antibiotics may be considered if a bacterial infection is suspected and treatment is appropriate.
If your tonsils remain enlarged but cause no symptoms, you may not need treatment. Your clinician may recommend monitoring them instead.
When enlarged tonsils cause significant problems with sleep, breathing or swallowing, an ENT specialist can assess the severity and discuss suitable options. In selected cases, surgery to remove the tonsils may be considered.
The decision to operate depends on your symptoms, examination findings and the benefits and risks of treatment. Not everyone with enlarged tonsils needs surgery.
Are enlarged tonsils normal?
Yes, enlarged tonsils can be normal, particularly in children and during or shortly after an infection.
Tonsils vary naturally in size, and their appearance alone does not determine whether treatment is needed. If you feel well, breathe comfortably and have no difficulty swallowing, larger-than-average tonsils may not cause a problem.
However, tonsils that repeatedly become inflamed or interfere with normal breathing or swallowing should be assessed. Persistent enlargement should also be reviewed if one tonsil is substantially larger than the other or its appearance changes unexpectedly.
The important consideration is whether the enlargement is associated with symptoms, rather than size alone.
Should I be worried about enlarged tonsils?
Enlarged tonsils are not usually serious, but you should be concerned if they cause breathing difficulties, significant swallowing problems or persistent unexplained changes.
For example, loud regular snoring, pauses in breathing during sleep, restless sleep or daytime tiredness may suggest sleep-disordered breathing. An assessment can help determine whether the tonsils are contributing to the problem.
Persistent one-sided enlargement, a lump in your neck, unexplained weight loss or ongoing throat pain also warrants medical review.
A particularly important complication is quinsy, which is an abscess that develops near a tonsil. It can cause severe one-sided pain, a muffled voice and difficulty opening the mouth.
Seek emergency medical help if you have difficulty breathing, cannot swallow saliva or develop rapidly worsening swelling in your mouth or throat.
When should I see a doctor about enlarged tonsils?
You should see a doctor about enlarged tonsils if they persist, keep becoming inflamed or cause problems with swallowing, breathing or sleep.
Your GP can examine your throat, ask about your symptoms and determine whether further investigation or referral to an ENT specialist is appropriate.
Seek an appointment if you have repeated episodes of tonsillitis, persistent one-sided enlargement, unexplained neck lumps or ongoing discomfort. If infections regularly affect your quality of life, you may also benefit from reading about recurrent tonsillitis treatment.
An ENT or throat specialist can assess whether the tonsils are contributing to your symptoms and explain the available treatment options. These may include monitoring, treating an underlying infection or considering surgery when clinically appropriate.
Most importantly, do not ignore breathing difficulties or an inability to swallow. These symptoms require emergency assessment rather than a routine appointment.
