Allergies are more than simply inconvenient for children and adults. The inflammation allergies cause may also lead to asthma, or another more serious condition. Mercy Clinic Asthma and Immunology in Washington, MO has a team that provides board-certified allergy treatment. An “allergist” is a doctor who has special training in the diagnosis and care of illnesses caused by allergic diseases. An allergist not only treats the symptoms, but also works to identify the causes of the illness and prevent future episodes. 

Our allergists help you take part in your own care. Our team will teach you how to avoid allergy and asthma triggers and manage your symptoms when they occur.
