It occurs when the immune system overreacts to an allergen, triggering a cascade of inflammatory responses. Symptoms can include difficulty breathing, swelling, hives and shock. Prompt administration of adrenaline is crucial for managing anaphylaxis. Pathophysiology 1. IgE-Mediated Response 2. Mast Cell Degranulation 3.…
