Allergic Diseases
Allergic diseases are a type of illness that occur when the immune system responds abnormally to a typically harmless substance such as pollen, dust, animal dander, or certain foods. When the immune system is exposed to these substances, it produces an antibody which leads to an allergic reaction. Symptoms of an allergic reaction can range from mild to severe and can include skin rashes, hives, coughing, wheezing, shortness of breath, and anaphylaxis (a severe and potentially life-threatening reaction). Allergic diseases can be managed through avoidance of the allergen, immunotherapy, and medications. Early diagnosis and treatment of allergic diseases can help improve quality of life and reduce the risk of severe reactions.
