What is Anaphylaxis?

Anaphylaxis is a severe, rapid-onset allergic reaction that affects the whole body and can be life-threatening if not treated immediately. It occurs when the immune system overreacts to a trigger, such as food, medication, insect stings, or other allergens, causing widespread release of histamine and other chemicals.

Anaphylaxis can impact multiple organ systems, including the skin, respiratory tract, gastrointestinal tract, and cardiovascular system. Symptoms can develop within minutes to hours after exposure and may progress rapidly. Prompt recognition and treatment are essential to prevent serious complications or death.

Is Anaphylaxis common?

Anaphylaxis is less common than mild allergic reactions but can occur in anyone at any age. Certain triggers, like peanuts, tree nuts, shellfish, insect stings, or medications, increase the likelihood of a severe reaction. People with a history of allergies or asthma are at higher risk.

Can Anaphylaxis be cured?

Anaphylaxis cannot be “cured,” but it can be prevented and effectively treated. Avoiding known triggers is critical, and immediate use of epinephrine during an attack can save lives. Long-term management includes education, emergency action plans, and sometimes allergy immunotherapy for specific triggers.
