Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, a runny nose, shortness of breath, or swelling. Many allergens such as dust or pollen are airborne particles. In these cases, symptoms arise in areas in contact with air, such as eyes, nose, and lungs.
Allergy Tests and Shots
Allergy treatment is based on avoidance of offending allergens through environmental control, medications to control symptoms, and immunotherapy (allergy shots). If immunotherapy is recommended, a solution is mixed specifically for you based on your allergy testing results and will be administered in your arm. The need for allergy medication may decrease or disappear as immunotherapy is advanced. Allergy injections are usually given three to five years, but some patients require immunotherapy indefinitely
