What is tonsillitis?
Tonsillitis refers to the inflammation of a tonsil--the large, fleshy, oval glands that lie in the lateral wall of the oral pharynx on either side of the throat. These glands contain cells that make antibodies that help fight infection.
What causes tonsillitis?
Tonsillitis can be caused by bacteria or viruses. Causes of tonsillitis include:
Streptococcus (commonly referred to as "strep") bacteria (the most common cause of tonsillitis)
The Epstein-Barr virus (infectious mononucleosis)
The herpes simplex virus
What are the symptoms of tonsillitis?
The following are the most common symptoms for tonsillitis. But each person may have slightly different symptoms. Symptoms may include:
Swollen, red tonsils (often coated with a yellow, gray, or white membrane)
Blisters or painful ulcerated areas on the throat
Sudden onset sore throat
Pain or difficulty with swallowing
Loss of appetite
Swollen and tender lymph nodes in the neck or jaw area
These symptoms may also occur if your child has a peritonsillar abscess:
Severe throat pain
Difficulty opening mouth
The symptoms of tonsillitis may resemble other conditions or health problems. Always consult your doctor for a diagnosis.
Can tonsillitis be prevented?
These suggestions may help to stop the spread of the contagious illnesses that are generally responsible for the spread of tonsillitis:
Keep your (and your child's) distance from anyone with tonsillitis or a sore throat.
Do not share utensils, drinking glasses, toothbrushes, or other objects with anyone who has tonsillitis or a sore throat.
Wash your (and your child's) hands frequently.
Cover your mouth when you cough or sneeze, and teach your children to do the same.
It is also possible that someone (especially a child) is carrying the strep bacteria (a common cause of tonsillitis) without presenting any symptoms of the infection. This person acts as a "carrier" and can transmit the infection to another person.
Treatment for tonsillitis
Specific treatment for tonsillitis will be determined by your doctor based on:
Your age, overall health, and medical history
Extent of the disease
Cause of the infection
Your tolerance for specific medications, procedures, or therapies
Expectations for the course of the disease
Your opinion or preference
Tonsillitis caused by a viral infection is treated differently than tonsillitis caused by a bacterial infection. Generally, tonsillitis caused by a bacterial strep infection can be successfully treated with an antibiotic medication. Viral tonsillitis is not treated with antibiotic medications because antibiotics are ineffective at defeating viral infections, but may be treated with other antiviral medications. With chronic and recurrent tonsillitis, a surgical procedure to remove the tonsils may be recommended.
If a peritonsillar abscess has developed, urgent treatment to prevent airway obstruction may be required.
