Allergists, also referred to as immunologists, are experts dedicated to preventing, diagnosing, and treating conditions related to the immune system. 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 associated with the immune system can vary widely, encompassing mild respiratory allergies, asthma, eczema, immunodeficiency disorders, autoimmune conditions, and acquired immune deficiency syndrome (AIDS).

An allergist/immunologist plays a crucial role in easing the symptoms of allergic reactions, thereby enhancing the quality of life for individuals affected by allergies. Through allergy testing, the source of the reaction can be identified, and various treatment options, including allergy shots, can significantly reduce or potentially eliminate the allergic response.
