Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.
Disorders of the immune system fall into four main categories: 1  immunodeficiency disorders (primary or acquired) 2  autoimmune disorders (in which the body's own immune system attacks its own tissue as foreign matter) 3  allergic disorders (in which the immune system overreacts in response to an antigen) 4  cancers of the immune system.
