The three stages of an allergic reaction are: 1. Sensitization: The immune system mistakenly identifies a harmless substance as harmful, producing antibodies. 2. Early-phase response: This occurs within minutes of exposure, leading to symptoms like itching, swelling, and redness due to histamine release. 3. Late-phase response: This can happen hours later, causing prolonged symptoms such as inflammation and tissue damage. Understanding these stages helps in timely intervention and management.
