The exact cause of rheumatoid arthritis, which gradually destroys the bone and the surrounding tissues of the affected joint are not known. A complex interaction between the environmental factors and hereditary factors has been proposed as the possible pathway for this disorder. An infection or autoimmune reaction (wherein the body’s defence cells act against the body itself) generally triggers a series of changes within the tissues of the joints that result in the symptoms. Hence, rheumatoid arthritis is considered as an autoimmune disorder that is caused due to malfunctioning of certain cells of the body’s immune system.¹
