BRAIN TO BODY® SITE GLOSSARY
Allergy
An Allergy is an immune system response to a foreign substance, known as an allergen, which is not typically harmful to the body. These allergens can include certain foods, pollen, pet dander, or dust mites. When someone with an Allergy comes into contact with an allergen, their immune system perceives it as an invader and overreacts by producing antibodies called Immunoglobulin E (IgE). This reaction can cause symptoms such as sneezing, itching, nasal congestion, hives, or in severe cases, anaphylaxis—a potentially life-threatening condition that requires immediate medical attention.
Allergies are quite common and can affect anyone, regardless of age, gender, or genetic background, although there is a higher risk for individuals with a family history of allergies. The diagnosis of allergies often involves skin or blood tests that identify specific allergens triggering the immune response. Management strategies typically include avoiding known allergens, taking medications like antihistamines to relieve symptoms, and in some cases, undergoing immunotherapy (Allergy shots) to desensitize the immune system to particular allergens. Living with allergies involves a combination of medical treatment and lifestyle adjustments to minimize exposure to potential triggers and manage symptoms effectively.
