Recurrent Tonsillitis

Op. Dr. Mehmet Ataman · Last updated: 2026-06-11

The tonsils are lymphoid tissues on either side of the throat that contribute to immune defence, particularly in childhood. Tonsillitis happens to every child from time to time; the real questions are how often it recurs and how much it disrupts life.

Symptoms

  • Sore throat, painful swallowing
  • Fever, fatigue
  • Red, enlarged tonsils, often with white-yellow exudate
  • Tender neck lymph nodes, bad breath

Viral or bacterial?

Most throat infections are viral and need no antibiotics — rest, fluids and pain control suffice. Bacterial tonsillitis caused by group A streptococcus, however, warrants antibiotic treatment, which speeds recovery and prevents complications such as rheumatic fever. The distinction is made by examination and throat testing when needed; starting antibiotics on your own for every sore throat is not appropriate.

When is it "recurrent"?

The internationally accepted thresholds (Paradise criteria) are:

  • 7 or more documented episodes in the last year, or
  • 5 or more per year over the last 2 years, or
  • 3 or more per year over the last 3 years

Patients meeting these thresholds are candidates for tonsillectomy.

Reasons for surgery besides frequency

  • Tonsil enlargement causing sleep apnea (now the most common indication)
  • Peritonsillar abscess, especially if recurrent
  • Chronic tonsillitis unresponsive to antibiotics, persistent bad breath and tonsil stones
  • Suspicious findings such as one-sided enlargement

Does removing the tonsils weaken immunity?

No. The immune system is a vast network throughout the body; there is no scientific evidence that properly indicated tonsillectomy weakens it. On the contrary, removing a focus of chronic infection clearly improves a child's general health, sleep and school attendance. The decision should be individual, based on the documented frequency and severity of attacks.

Frequently Asked Questions

What are the symptoms of tonsillitis?

Tonsillitis causes a sore throat, painful swallowing, fever and fatigue. The tonsils are often red and enlarged, sometimes with white-yellow exudate, and there may be tender neck lymph nodes and bad breath.

Do I need antibiotics for every sore throat?

No. Most throat infections are viral and need no antibiotics; rest, fluids and pain control are enough. Bacterial tonsillitis from group A streptococcus does warrant antibiotics, and the distinction is made by examination and throat testing when needed.

How many tonsil infections per year count as recurrent?

The internationally accepted Paradise criteria define recurrent tonsillitis as 7 or more documented episodes in one year, 5 or more per year over two years, or 3 or more per year over three years. Patients meeting these thresholds are candidates for tonsillectomy.

What are reasons for tonsil surgery besides frequent infections?

The most common indication today is tonsil enlargement causing sleep apnea. Other reasons include recurrent peritonsillar abscess, chronic tonsillitis unresponsive to antibiotics, persistent bad breath with tonsil stones, and suspicious findings such as one-sided enlargement.

Does removing the tonsils weaken immunity?

No. The immune system is a vast network throughout the body, and there is no scientific evidence that a properly indicated tonsillectomy weakens it. Removing a focus of chronic infection often improves a child's general health, sleep and school attendance.
