Allergists, also referred to as immunologists, are medical professionals dedicated to the prevention, diagnosis, and treatment of disorders affecting the immune system. These conditions may involve allergic responses to various triggers such as tree and grass pollen, 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 or immunologist can significantly ease the symptoms associated with allergic reactions, thereby enhancing the quality of life for individuals suffering from allergies. Allergy testing is instrumental in identifying the source of the reactions, and various treatment options, including allergy shots, can help minimize or completely eliminate these reactions.
