Subtitle Forum: Is Allergy an Immune Disease?
Allergies are a common condition that can cause a range of symptoms from mild to severe. The symptoms of an allergic reaction occur when the body’s immune system responds to a substance, such as pollen or pet dander, that it sees as a threat. While allergies are not considered immune diseases, they are closely related to the immune system.
Immune System
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against foreign invaders. When the body is exposed to something it sees as a threat, it mounts an immune response and releases certain chemicals, such as histamine, to fight off the invader. In people with allergies, the body mistakenly identifies an otherwise harmless substance as a threat and mounts an immune response.
Allergens
Allergens are substances that cause an allergic reaction. These can include pollen, pet dander, dust mites, mold, food, and certain medications. When a person with an allergy is exposed to an allergen, their body releases histamine and other chemicals in an attempt to fight off the allergen. This causes the symptoms of an allergic reaction, which may include a runny nose, sneezing, coughing, itchy eyes, and skin rashes.
Immunotherapy
Immunotherapy is a type of treatment for allergies that involves exposing a person to small, increasing amounts of an allergen over a period of time. The goal of immunotherapy is to help the body become used to the allergen and to decrease the severity of allergic reactions. Immunotherapy may involve injections, oral medications, or nasal sprays, depending on the type of allergy.
Allergy may not be considered an immune disease, but it is closely related to the immune system. Allergies occur when the body’s immune system mistakenly identifies a harmless substance as a threat and responds by releasing histamine and other chemicals. While there is no cure for allergies, immunotherapy can help reduce the severity of allergic reactions.
