Can tonsil and adenoid problems be heriditary?

Possibly: I believe there is a genetic component to most diseases. The ability of the immune system to overcome infectious diseases is probably genetic. But even though this immune background is important, the development of viral or bacterial infections of the tonsils and adenoids is the result of being exposed to others who harbor these infectious agents and this is not genetic.

Maybe: Etiology of big tonsils and adenoids not known. Probably agenetic component because siblings tend to have big tonsils and adenoids and runs in families.Children exposed to bad viruses such as RSV, that young children getscan cause a pretty bad upper respiratory infection— are more likely later on to have bigger tonsils and adenoids.
