The tonsils are two masses of lymphatic (immune system) tissue located at the back of the throat. They produce antibodies designed to help you fight respiratory infections. They are small at birth and gradually increase in size until age 8 or 9. They begin to shrink around aqe 11 or 12 but never entirely disappear. When these tissues become infected, the resulting condition is called tonsillitis.
Tonsillitis most commonly affects children between the ages of 3 and 7, when tonsils may play their most active infection-fighting role. As the child grows and the tonsils shrink, infections become less common. Tonsillitis is usually not serious unless a tonsillar abscess develops. When this happens, the swelling can be severe enough to block your child's breathing. Ear infections and adenoid problems (swellings at the back of the nasal cavity above the tonsils) may occur at the same time.
