Hypersensitivities, or allergies, involve an overreaction of the immune system to an allergen. This reaction results in a variety of symptoms ranging from hives or congestion to more severe reactions that can result in the inability to breathe causing anaphylactic shock. Anaphylaxis is a severe, systemic reaction that can cause tightening of the airway and other symptoms, including abdominal pain, hives, slurred speech, and wheezing.
