The growth and frequent inflammation of the tonsils and adenoids can cause problems such as hearing loss, orthodontic disorders, facial development disorders, speech disorders, snoring, mouth breathing, night coughs, and nasal discharge in children. When tonsil and adenoid enlargements reach the size that will narrow the upper respiratory tract, serious problems such as snoring and apnea start serious problems such as breathlessness during sleep. Also known as rheumatic fever, the disease is a complication caused by antibodies against group A beta-hemolytic streptococci. It can cause disorders in the heart valves.
