Allergists, often referred to as immunologists, are medical professionals dedicated to the prevention, diagnosis, and treatment of immune system disorders. These disorders can manifest as allergic reactions triggered by various factors such as tree and grass pollen, specific foods, medications, pet hair, insect stings, and more.

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

An allergist/immunologist can provide relief from allergy symptoms, significantly enhancing the quality of life for those affected by allergies. Through allergy testing, the source of the allergic reaction can be identified, and various treatment options, including allergy shots, can help mitigate or completely resolve the reactions.
