Allergists, who are also referred to as immunologists, are medical professionals dedicated to the prevention, diagnosis, and treatment of immune system disorders. These conditions may involve allergic responses to various triggers such as pollen from trees and grasses, specific foods, medications, pet dander, insect stings, and more.

Diseases related to the immune system can range from mild respiratory allergies to more severe conditions like asthma, eczema, immunodeficiency disorders, autoimmune diseases, and acquired immune deficiency syndrome (AIDS).

An allergist/immunologist can assist in alleviating the symptoms associated with allergic reactions, leading to enhanced quality of life for those affected. Allergy testing can identify the source of the reaction, and various treatment options, including allergy shots, can help minimize or completely resolve the reaction.
