Hypersensitivity refers to an exaggerated or inappropriate immune response to a substance, which can lead to tissue damage and various allergic reactions. It is classified into four types: Type I (immediate, such as Allergies), Type II (cytotoxic, involving antibodies against cell surfaces), Type III (immune complex-mediated), and Type IV (delayed-type, involving T cells). Symptoms can range from mild reactions, like hives, to severe anaphylaxis. Proper diagnosis and management are essential to mitigate the effects of hypersensitivity reactions.
The accented syllable in "Hypersensitivity" is "-sen-".
Type IV Hyper sensitivity. AKA delayed hypersensitivity. Can be classified into: -contact -tuberculin -granuloma

Type II hypersensitivity is also known as cytotoxicity hypersensitivity and it may affect variety of organs and tissues. The antigens are endogenous and exogenous chemicals. Type III Hypersensitivity complex type of hypersensitivity and it may affect individual organs like skin, Liver etc.
The most common type of immediate hypersensitivity is type I hypersensitivity, also known as allergic reactions. This type of hypersensitivity involves the production of IgE antibodies in response to an allergen, which leads to the release of histamine and other mediators that cause symptoms such as itching, hives, and anaphylaxis.
