Understanding Allergies: Causes and Reactions

The video tutorial explores allergies, their causes, and how they manifest. It explains that allergies are caused by the immune system's hypersensitivity to environmental triggers, known as allergens. Common allergens include foods, latex, and pollen. The video details how allergic reactions occur, involving proteins like IgG and chemicals like histamine. It also covers managing allergies with antihistamines and adrenaline, and emphasizes prevention through early detection. Testing methods such as batch and blood testing are discussed for diagnosing allergies.
