Recurrent Tonsillitis: When Is Tonsillectomy Needed?

What is tonsillitis?

Tonsillitis is an infection causing throat pain and fever. Most sore throats are viral, and some are bacterial, with streptococcus being the most well-known.

Recurring infections don't always mean surgery is needed.

What are the symptoms?

• Throat pain, and pain when swallowing
• Fever
• Redness and swelling of the tonsils, sometimes with white spots
• Swollen neck glands
• Bad breath
• In children: sometimes abdominal pain or vomiting

Cough, a runny nose, and hoarseness usually suggest a viral infection.

How is it diagnosed?

The doctor examines the throat and may take a rapid swab to check for streptococcus bacteria. The swab result helps determine whether antibiotics are needed.

How is a single episode treated?

• Pain relievers and fever reducers
• Adequate fluids and soft, cold food
• Rest
• Antibiotics: when bacterial infection is confirmed. Complete the full course as directed, even if you feel better.

Be careful

Antibiotics don't help with viral infections, and using them unnecessarily causes side effects and bacterial resistance.

Don't give aspirin to children.

When is tonsillectomy recommended?

Doctors typically consider surgery when infections are documented by a doctor and recurring, such as:

• 7 or more episodes in one year
• Or 5 or more episodes per year for two years
• Or 3 or more episodes per year for three years

A documented infection means an examination by a doctor showing fever, pus on the tonsils, swollen neck glands, or a positive swab.

Surgery may also be recommended in other situations, such as recurrent tonsil abscess, sleep apnea, or frequent absence from school or work.

If infections are less frequent than this, monitoring is usually the better option, as infections decrease with age in many children.

What can I do?

• Keep a record of each infection, its symptoms, and swab result — this helps the doctor make the decision.
• Wash hands thoroughly, and don't share cups or eating utensils.
• Change your toothbrush after recovering.
• Keep children away from cigarette and shisha smoke.

Tonsil stones: small, foul-smelling white lumps, usually not dangerous. Rinsing and dental cleaning help reduce them.

When should I see a doctor?

• If throat pain is severe with high fever.
• If symptoms last more than a week.
• If infections recur frequently.
• If one tonsil is noticeably larger than the other in adults.

Go to the emergency room immediately if:

• You cannot swallow saliva, or saliva is drooling from the mouth
• Opening the mouth is difficult
• The voice becomes muffled with severe pain on one side of the throat
• Difficulty breathing appears
• Signs of severe dehydration appear

These may be signs of a peritonsillar abscess, which needs urgent drainage.

Remember

• Most sore throats are viral.
• A swab determines the need for antibiotics.
• Surgery depends on the number and severity of documented infections.
• Difficulty opening the mouth or swallowing saliva is a medical emergency.
