ALLERGIES. What does an allergy mean? An allergy refers to an exaggerated reaction by our immune system in response to bodily contact with certain foreign substances.
1. Delayed Hypersensitivity – Mediated by helper T cells and macrophages; independent of antibodies.
2. Immune-complex Hypersensitivity – Mediated by antigen-antibody complexes deposited in tissue.
3. Immediate Hypersensitivity – Mediated by IgE antibodies, mast cells, and eosinophils.
A severe reaction can lead to anaphylaxis, which is death due to circulatory and respiratory failure.
The best avoidance measure for a pet allergy is removing the animal from the house completely if you so emotional and cant do that, and keep it off of furniture and bedroom as much as possible.
When you get allergy shots (immunotherapy), your allergist or doctor injects small doses of substances that you are allergic to under your skin.
This helps your body "get used to" the allergen, which can result in fewer or less severe symptoms of allergic rhinitis.
