Difference Between Osteoarthritis and Rheumatoid Arthritis

Arthritis is a common ailment people experience as they age. All Arthritis conditions affect the joints of the body in some form, with almost all those afflicted with the disease reporting pain. The most common form of Arthritis is Osteoarthritis, with a similar form being Rheumatoid Arthritis. Despite being subgroups of Arthritis, there are key differences between Osteoarthritis and Rheumatoid Arthritis.

Osteoarthritis is also known as Degenerative Arthritis, in that joints and connecting bone degrade, leading to a loss of cartilage for bone support. The hands, feet, and spine are the areas most commonly affected. Those who are obese, elderly, suffer from joint stress, or muscle weakness are at greater risk for the disease. Treatments for this disease include lifestyle changes such as exercise and weight loss which are commonly recommended.

The other common form of Arthritis is called Rheumatoid Arthritis. Unlike Osteoarthritis, RA is an inflammatory response that is chronic. Joints are similarly affected as in Osteoarthritis, however, the membrane that lines the joints are what become inflamed instead. Small joint areas such as the hands and feet are affected most commonly. Unlike Osteoarthritis, this form of Arthritis is an autoimmune disorder. The body's immune system actually attacks normal tissue in the body. Treatments includes anti-inflammatory drugs, pain relieving drugs, and drugs that prevent future joint degradation.

Despite affecting similar areas of the body, Osteoarthritis and RA are two very different conditions. Osteoarthritis will affect those with demographic risk factors, while Rheumatoid Arthritis can attack anyone, as it is an autoimmune disorder.
