Is rheumatoid arthritis hereditary?
Arthritis means inflammation of the joints. Rheumatoid arthritis (RA) is a common form of arthritis. About 1 in 50 people develop RA at some stage in their life. It can happen to anyone, and it is not a hereditary disease. It can develop at any age, but most commonly starts in middle adult life (aged 40-60). It is three times more common in women than in men.
Some scientists believe that the tendency to develop rheumatoid arthritis may be genetically inherited. It is suspected that certain infections or factors in the environment might trigger the immune system to attack the body’s own tissues, resulting in inflammation in various organs of the body such as the lungs or eyes. http://www.medicinenet.com/rheumatoid_arthritis/article.htm This is an autoimmune disease that affects only about 1% of the nation, not 1 in 100 people. Do not mistake it for arthritis or osteoarthritis.
