Main classifications of allergic diseases where the immune system overreacts to foreign substances.
Overview
Types of Allergies
Allergies are a group of diseases caused by the immune system's excessive reaction to normally harmless substances (allergens). Based on classifications by WHO and the Japanese Society of Allergology, they are categorized into respiratory allergies, skin allergies, food allergies, drug allergies, insect allergies, eye allergies, and systemic allergies (anaphylaxis). According to the Gell-Coombs classification, they are divided into Type I to Type IV immune reactions, each with different symptoms and mechanisms. It is estimated that 10-30% of the population has some form of allergy, making it a significant health issue affecting quality of life.
