Rheumatoid arthritis is an autoimmune disorder that causes the immune system to be attacked and weakened by mistake. With RA, malfunctioning of the immune system particularly affects the synovial membranes that join the joints, causing pain and discomfort that can eventually lead to permanent bone damage.
Many physicians believe that genetics may play a role in the development of RA, and researchers have identified several possible viruses and bacteria that begin a similar immune response that may be related to the disease. Age and sex are also possible variables in the development of RA, as 75% of the 1.3 million Americans diagnosed with the disease are women and most cases occur in men and women between the ages of 40 and 60 years.
Other autoimmune diseases include lupus, psoriasis, and multiple sclerosis (MS). Talk to your doctor about your symptoms for an accurate diagnosis.
