Tonsillitis is the inflammation of the tonsils. Tonsils
are two oval-shaped pads of tissue at the back of the throat. Tonsils act
as filters, trapping germs that could otherwise enter your airways and cause
infection. They also produce antibodies to fight infection. But sometimes
the tonsils themselves become infected. Overwhelmed by bacteria or
viruses, they swell and become inflamed, a condition known as tonsillitis.
Tonsillitis is common with children. Most cases of
tonsillitis are caused by infection with a common virus, but bacterial
infections also may cause tonsillitis. The condition can occur occasionally or
recur frequently.
SYMPTOMS
Tonsillitis most commonly affects children between
preschool ages and the mid-teenage years. Common signs and symptoms of
tonsillitis include:
- Red,
swollen tonsils
- White
or yellow coating or patches on the tonsils
- Sore
throat
- Difficult
or painful swallowing
- Fever
- Enlarged,
tender glands (lymph nodes) in the neck
- A
scratchy, muffled or throaty voice
- Bad
breath
- Stomachache,
particularly in younger children
- Stiff
neck
- Headache
In children, symptoms may
also include:
- Nausea
- Vomiting
- Abdominal
pain
WHY
DO TONSILS GET INFECTED?
The tonsils are the immune system's first line of defense
against bacteria and viruses that enter your mouth. This function may make the
tonsils particularly vulnerable to infection and inflammation. However, the
tonsil's immune system function declines after puberty — a factor that may
account for the rare cases of tonsillitis in adults.
COMPLICATIONS
Inflammation or swelling of the tonsils from frequent or
ongoing (chronic) tonsillitis can cause complications such as:
- Difficulty
breathing
- Disrupted
breathing during sleep
- Infection
that spreads deep into surrounding tissue (tonsillar cellulitis)
- Infection
that results in a collection of pus behind a tonsil (peritonsillar
abscess)
TREATMENT
Treatment for tonsillitis will depend in part on the
cause. To determine the cause, your doctor may perform a rapid strep test or
throat swab culture. Both tests involve gently swabbing the back of the throat
close to the tonsils with a cotton swab. A lab test can detect a bacterial
infection. A viral infection will not show on the test, but may be assumed if
the test for bacteria is negative
If tests reveal bacteria, treatment will consist of antibiotics to
cure the infection. Symptoms will likely improve within two or three days after
starting the antibiotic. It is important to take all of the medication your
doctor prescribes to make sure the bacteria are gone.
PREVENTION
The germs that cause viral and bacterial tonsillitis are
contagious. Therefore, the best prevention is to practice good hygiene. Teach
your child to:
- Wash
his or her hands thoroughly and frequently, especially after using the
toilet and before eating
- Avoid
sharing food, drinking glasses, water bottles or utensils
- Replace
his or her toothbrush after being diagnosed with tonsillitis
To help your child prevent the spread of a bacterial or
viral infection to others:
- Keep
your child at home when he or she is ill
- Ask
your doctor when it's all right for your child to return to school
- Teach
your child to cough or sneeze into a tissue or, when necessary, into his
or her elbow
- Teach
your child to wash his or her hands after sneezing or coughing
