Can enlarged tonsils in a child contribute or worsen cough-variant asthma or general allergies?

Maybe: Tonsilar enlargement or hypertrophy may block the airway of a child and make breathing more difficult. This could provoke an asthma event. This condition should be elevated by you pediatric physician, family physician, or emergency department as soon as possible.

Yes: Allergic rhinitis & enlarged tonsils may interfere with normal nasal breathing resulting in congestion (nasal stuffiness) & mouth breathing. Complications include snoring, hoarseness, bad breath, sleep apnea, sleep disturbances, malocclusion of the teeth, and other anatomic distortions of the mouth. Mouth breathing worsens asthma because of inhalation of relatively cold, dryer air into the lungs.
