Anaphylaxis is a potentially life-threatening and severe allergic reaction. It occurs when the body's immune system overreacts to an allergen, such as a certain food, insect sting, medication, or latex. Anaphylaxis can cause symptoms that affect different body systems, including skin rash, swelling, difficulty breathing, low blood pressure, rapid heartbeat, and gastrointestinal problems. It is considered a medical emergency and requires immediate treatment with epinephrine and medical attention.
