The human body comes in contact with many potential intruders like allergens or pathogens that can pose a threat. The body is enabled with its own defenses to combat invaders and protect itself. However, in some instances the defenses are breached, causing an interruption in the body’s enzyme systems that can destroy vital tissues.

The allergic system, also known as the immune system, is a complex network of cells, tissues, and organs that work together to defend the body against harmful substances and protect it from infections. Its primary function is to recognize and respond to foreign substances, known as allergens, in order to maintain the body’s overall health and well-being. At times, it may overreact creating allergic disorders, which nurses must identify and know how to treat. This chapter will explore those allergic disorders and the medical and nursing treatment.
