Thrombosis

Autoimmune diseases are caused by the body producing an immune response against its own tissues or even organs. The entire cause of autoimmune disease is so far still unknown. Some autoimmune diseases run in families, and certain cases may be triggered by infections or other environmental factors. The diseases generally fall into two types: systemic and organ specific. Systemic diseases damage many organs, whereas in organ specific diseases only a single organ or tissue is directly damaged by the autoimmune process.
