Adenoid symptoms mainly refer to the symptoms caused by adenoid hypertrophy. Local symptoms include symptoms in the nose, ears, throat and lower respiratory tract. Nasal symptoms include nasal congestion, runny nose, and an occlusive nasal sound when speaking. Ear symptoms are mainly caused by adenoid hypertrophy compressing the eustachian tube, which may include ear stuffiness, ear pain and hearing loss. Pharyngeal and lower respiratory tract symptoms may include nasopharyngeal downflow, irritation of respiratory mucosa causing discomfort in the pharynx and paroxysmal cough. Systemic symptoms are mainly stunting as well as poor nutritional status, and symptoms such as excessive dreaming, easy awakening, slow reaction and poor concentration.
