A body immune system is present to protect its body cells from foreign substances that cause diseases. It produces antibodies against the foreign antigens leading to their destruction and hence death. In addition to this, various immune cells like lymphocytes and monocytes disrupt foreign cells by the process of phagocytosis in a normal biological condition. But sometimes, due to an abnormal immune response, body immune system starts attacking its own healthy cells and tissues. It happens when the lymphocytes cannot distinguish between antigens and body own cells. This leads to destruction of bodys healthy tissues, which sometimes leads to death. Such conditions are referred to as the autoimmune diseases. The main consequence of such diseases is inflammation that leads to swelling, redness and chronic pain. The survey reports reflect that females get more acquainted with these diseases as compared to males.
Currently, no such authenticate and satisfactory reason has yet been found for the occurrence of these diseases. These diseases include different patterns of physical and biological issues which are difficult to be distinguished. Diagnosis of such diseases also forms a major challenge to the doctors and the researchers. Presently, scientists are trying to find better ways for the diagnosis and treatment of such diseases.
