Severe Allergic Reaction Facts. Anaphylaxis is a severe allergic reaction that occurs rapidly and causes a life-threatening response involving the whole body. This reaction can lead to difficulty breathing and shock ultimately leading to death. For an anaphylactic reaction to occur, you must have been exposed in the past to the substance that causes the reaction, called the antigen. A bee sting, for example, may not cause an allergic reaction the first time.
