Children with adenoid hypertrophy are often prone to poor eating and anorexia, so it is recommended to supplement protein, mainly high-quality protein, such as fish, meat, chicken, and vegetable protein. The main prevention of adenoid hypertrophy in children is respiratory infections. Repeated episodes of upper respiratory infections may stimulate hypertrophy of the adenoids. In addition, children with allergic rhinitis and sinusitis are advised to actively treat allergic rhinitis and sinusitis to avoid further adenoid hyperplasia and hypertrophy and other serious comorbidities after repeated secretion stimulation. For children with adenoid hypertrophy, parents are advised to avoid respiratory infections during the fall and winter seasons, as well as to actively control allergic symptoms and treat primary diseases.
