Recurrent Tonsillitis
Recurrent tonsillitis is a condition characterized by multiple episodes of inflammation and infection of the palatine tonsils, which are the two round lumps of tissue at the back of the throat. Tonsillitis is considered recurrent when a person experiences multiple infections within a year. The standard clinical definition typically includes 7 or more episodes in the past year, 5 or more episodes per year for 2 consecutive years, or 3 or more episodes per year for 3 consecutive years. Recurrent tonsillitis can significantly impact quality of life, causing repeated absences from school or work, difficulty eating and drinking, and systemic symptoms like fever and fatigue.
Causes
- Bacterial infections - Streptococcus pyogenes (group A streptococcus) is the most common bacterial cause, though other bacteria can also be responsible.
- Viral infections - Viruses including adenovirus, influenza virus, parainfluenza virus, enteroviruses, and Epstein-Barr virus can cause tonsillitis.
- Chronic bacterial biofilms - Colonies of bacteria that form protective coatings and resist antibiotic treatment may persist in the tonsillar crypts (small pockets on the tonsil surface).
- Tonsillar microbiome disruption - Changes in the normal balance of bacteria that live in the tonsils can contribute to recurrent infections.
- Compromised immune function - Conditions that affect the immune system may make some individuals more susceptible to recurrent infections.
- Genetic factors - Family history may play a role, as some individuals may have a genetic predisposition to recurrent tonsillitis.
- Environmental factors - Exposure to pollutants, cigarette smoke, or allergens may increase susceptibility to infections.
- Close contact - Frequent exposure to others with throat infections, particularly in settings like schools or daycare centers.
- Anatomical factors - Deep tonsillar crypts that can trap bacteria and debris may contribute to recurrent infections in some individuals.
Signs and Symptoms
- Frequent sore throat - Pain or discomfort that recurs multiple times per year.
- Red, swollen tonsils - Enlarged tonsils that may have white or yellow spots or pus.
- Difficulty swallowing - Pain or discomfort when eating or drinking.
- Fever - Temperature elevation that accompanies acute episodes.
- Tender, swollen lymph nodes in the neck - Palpable glands under the jaw or in the neck.
- Bad breath (halitosis) - Persistent bad breath despite good oral hygiene.
- Ear pain - Referred pain to the ears, especially during swallowing.
- Headache - Often accompanies acute episodes.
- Fatigue and general malaise - Feeling unwell and lacking energy during and between episodes.
- Voice changes - Muffled or "hot potato" voice due to swollen tonsils.
- Sleep disturbances - Including snoring or sleep apnea due to enlarged tonsils.
- Reduced appetite and weight loss - Due to pain when eating.
Diagnosis
Medical History
Your doctor will ask detailed questions about the frequency, duration, and severity of your tonsillitis episodes, treatments attempted, response to antibiotics, and impact on daily activities. A documented history of multiple episodes meeting the criteria for recurrent tonsillitis is essential for diagnosis.
Physical Examination
Examination of the throat, tonsils, ears, nose, and neck during an active infection helps assess the severity of inflammation and infection. Signs of chronic tonsillitis, such as persistently enlarged tonsils with deep crypts, may be visible even between acute episodes.
Throat Culture or Rapid Strep Test
During an active infection, samples from the throat and tonsils may be collected to test for specific bacteria, particularly group A streptococcus. This helps guide antibiotic treatment and distinguish bacterial from viral causes.
Blood Tests
Complete blood count (CBC) may show elevated white blood cells during bacterial infections. Other blood tests may be performed to check for mononucleosis (Monospot test) or to evaluate overall health and immune function.
Imaging Studies
In some cases, CT scans or MRI may be ordered to assess for complications such as peritonsillar abscess or to evaluate the size of the tonsils and surrounding structures, particularly if airway obstruction is a concern.
Treatment Options
Antibiotics
For bacterial tonsillitis, antibiotics such as penicillin, amoxicillin, or macrolides (for those allergic to penicillin) are prescribed. Complete courses of antibiotics are essential to eradicate the infection and prevent complications. For recurrent cases, different antibiotics or longer courses may be needed.
Symptom Management
Pain relievers like acetaminophen or ibuprofen reduce pain and fever. Throat lozenges, warm saltwater gargles, and drinking plenty of fluids help soothe the throat and maintain hydration. Voice rest and humidified air can also provide relief during acute episodes.
Prophylactic Antibiotics
In some cases, particularly when streptococcal infections are recurrent, long-term low-dose antibiotics may be prescribed to prevent new infections. This approach is generally considered before surgical intervention in certain patients.
Surgical Management (Tonsillectomy)
Surgical removal of the tonsils is recommended when recurrent tonsillitis significantly impacts quality of life and meets established frequency criteria. Modern techniques include traditional "cold knife" dissection, electrocautery, radiofrequency ablation, or coblation, each with its own recovery profile and complication rates.
Home Remedies
Warm Salt Water Gargles
Dissolve half a teaspoon of salt in 8 ounces of warm water and gargle for 30 seconds several times daily. This helps reduce swelling, loosens mucus, and can remove irritants and bacteria from the throat.
Hydration
Drink plenty of warm fluids such as herbal teas with honey, clear broths, or warm water with lemon. Staying well-hydrated helps prevent dehydration and keeps the throat moist, reducing irritation.
Throat Lozenges and Sprays
Over-the-counter lozenges containing benzocaine, menthol, or eucalyptus can temporarily numb the throat and reduce pain. Throat sprays with similar ingredients can also provide relief.
Humidification
Using a humidifier or steam inhalation adds moisture to the air, which can soothe irritated throat tissues and thin mucus secretions. Taking a warm shower or breathing in steam from a bowl of hot water can achieve similar effects.
Rest
Getting adequate rest and sleep helps support immune function and recovery during acute episodes. Voice rest (limiting talking) can also reduce strain on the throat.
Preventive Care
- Practice good hand hygiene by washing hands frequently and thoroughly, especially before eating and after contact with someone who has a throat infection.
- Avoid sharing utensils, food, drinks, or personal items that may transmit bacteria or viruses.
- Replace your toothbrush after a throat infection to prevent reinfection.
- Maintain good oral hygiene, including regular brushing and flossing, to reduce bacteria in the mouth and throat.
- Avoid irritants like cigarette smoke, which can inflame the throat and make it more susceptible to infection.
- Stay hydrated to keep the throat moist and help flush out toxins.
- Support immune function through a balanced diet, regular exercise, adequate sleep, and stress management.
- Avoid close contact with people who have active throat infections when possible.
- Complete the full course of antibiotics when prescribed, even if symptoms improve before the medication is finished.
- Attend regular follow-up appointments with your healthcare provider to monitor recurrent infections and adjust treatment plans as needed.
Surgical Options
Tonsillectomy
The complete surgical removal of both palatine tonsils. Modern techniques include traditional dissection, electrocautery, radiofrequency ablation, or coblation, each with different profiles for bleeding risk, pain, and recovery time. This is the definitive treatment for recurrent tonsillitis that meets established frequency criteria and significantly impacts quality of life.

Removal of both the tonsils and adenoids is often performed together, particularly in children. The adenoids are similar to tonsils but located in the back of the nasal passage. When both tissues are chronically infected or enlarged, removing both can provide better outcomes for breathing, sleep, and infection control.

A less invasive procedure that removes most of the tonsil tissue while preserving the outer capsule. This technique may result in less postoperative pain and a lower risk of bleeding compared to complete tonsillectomy, though there is a small chance that remaining tissue could become infected in the future.

Uses radiofrequency energy and saline to remove tonsil tissue at a lower temperature than electrocautery, potentially resulting in less damage to surrounding tissues and reduced postoperative pain. Recovery may be somewhat faster compared to traditional techniques.
