“How can I prevent ear infections?”

Your question is not clear, do you get infection like swimmer's ear or it is middle ear infection.

First the question is what type of an ear infection do you have/ If it is an external ear infection {ear canal} then the answer would be to keep the ear canal dry. If it is a middle ear infection then we are looking at the respiratory system for the answer. Are you a smoker or do you work around any type of nasal irritant? Do you have frequent colds or allergies? These are things that cause irritation of the lining of the middle ear and eustachian tube and can lead to chronic ear infections Certain tumors of the middle ear may also be a cause of chronic ear infections An ear examination would be most helpful in identifying the cause of a chronic ear problem.
