What causes enlarged adenoids?

The common causes of adenoid hypertrophy are repeated episodes of acute and chronic nasopharyngitis, as well as inflammation of the adjacent tissues of the nasopharynx such as sinus and tonsillitis involvement, which stimulates adenoid tissue proliferation, manifested as adenoid hypertrophy.
1. Repeated episodes of inflammation in the nasopharynx, adenoids in the inflammatory response to the constant stimulation, it is possible to lead to the site of hyperplasia reaction, thus causing adenoid hypertrophy.
2. Sinusitis, tonsillitis: inflammation of neighboring tissues progresses, and the infection can spread to the nasopharynx, resulting in adenoid lymphoid hyperplasia.
3. Adenoids themselves: bacteria or viruses directly invade the adenoids, the infection stimulates the occurrence of pathological hyperplasia and hypertrophy.
Adenoid hypertrophy may also be caused by other factors, if there is adenoid hypertrophy, it is also recommended to go to the hospital in time, standardized treatment.
