What Are the Symptoms of Immediate Hypersensitivity?
Symptoms can range from mild to severe and may include urticaria (hives), angioedema (swelling), nasal congestion, wheezing, and anaphylactic shock. Severe reactions, known as anaphylaxis, can be life-threatening and require immediate medical attention. These symptoms are due to the systemic effects of the mediators released during the reaction.
