Allergists, often referred to as immunologists, are medical experts dedicated to preventing, diagnosing, and treating ailments 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 hair, insect bites, and more.

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

An allergist/immunologist can provide relief from allergy symptoms, significantly enhancing the overall quality of life for individuals suffering from allergies. Allergy testing can identify the source of the reaction, while various treatment options, including allergy shots, may help lessen or completely eradicate the reaction.
