Like the soldiers who protect the borders of the country are always at risk of injury, Adenoids similarly are the soldiers of our body that are at risk of disease. Along with tonsils, they traps viruses and bacteria and protect us from infection during childhood.
They usually enlarge (catch infection) due to this role play of defence mechanism, but soon return to their normal size. However, sometimes they fail to return to their normal size and remain enlarged. Enlarged adenoids block airways and cause other symptoms too.
Allergies and recurrent throat and nasal infections are also among the leading causes of adenoids.
