Hypersensitivity (Allergic Reactions)

Hypersensitivity reactions, also known as allergic reactions, occur when the body has an extreme response to a specific trigger, such as pollen or certain foods. There are four types of hypersensitivity reactions, each with different mechanisms and effects on the body. These reactions can cause a range of symptoms, from mild discomfort to life-threatening conditions. Understanding the different types of hypersensitivity reactions can help in identifying and managing allergic conditions.
