Rheumatoid arthritis is a type of inflammatory arthritis that is
also classified as an autoimmune disorder. This means that the
nervous system sends errant messages to the immune cells to
attack the body’s own tissues – in this case, the synovial fluid
that lubricates the joints. Symptoms of rheumatoid arthritis
include painful swelling, stiffness and deformities of the
joints, most commonly in the hands, wrists and feet; typically,
joints on both sides of the body are affected. While the cause
of rheumatoid arthritis is largely unknown, genetic,
environmental, and hormonal factors are suspected. Treatment
programs usually center on medications to control the symptoms
and stop or slow the progressive joint damage; exercise may also
be included to help the patient retain strength and mobility.
