What is an Autoimmune Disease?

An autoimmune disease occurs when the body’s immune system starts reacting against some of its own tissue. Normally, the role of the immune system is to protect the body against foreign invaders such as microorganisms and other harmful substances. The body destroys these antigens by producing antibodies. However, when antibodies are mistakenly directed against the body’s own cells, tissues and organs it results in inflammation and damage leading to autoimmune disease. Autoimmune disease can be either inherited or acquired disorder. Generally, autoimmune diseases are categorized into two types: organ-specific or localized where only one organ is affected and systemic where the disease is widely spread throughout the body. An autoimmune disease can cause destruction of certain type of body tissue, abnormal growth of an organ or changes in function of an organ.
