Atopy is a type I hypersensitivity reaction that involves IgE antibodies, leading to immediate allergic responses like hay fever and Asthma. Anaphylaxis is a severe, life-threatening allergic reaction that involves a systemic release of histamine and other mediators, causing symptoms such as difficulty breathing and low blood pressure. Both atopy and anaphylaxis are mediated by an exaggerated immune response to normally harmless substances.

Inappropriate or excessive immune responses to antigens are?
Inappropriate or excessive immune responses to antigens are known as hypersensitivity reactions. These can result in allergic reactions, autoimmune diseases, or immune-mediated tissue damage. Examples include allergic rhinitis, systemic lupus erythematosus, and rheumatoid arthritis.
What happens in the body during anaphylaxis?
During anaphylaxis, the immune system overreacts to a typically harmless substance, releasing large amounts of histamine and other chemicals. This leads to a systemic inflammatory response, causing symptoms such as swelling, hives, difficulty breathing, a drop in blood pressure, and potentially life-threatening complications. Immediate medical attention is necessary to treat anaphylaxis.

What is a life threatening reaction to a foreign substance?
