Arthritis is an inflammation of the joints. It can affect one joint or multiple joints. There are more than 100 different types of arthritis, with different causes and treatment methods. Two of the most common types are osteoarthritis (OA) and rheumatoid arthritis (RA).
Cartilage is a firm but flexible connective tissue in your joints. It protects the joints by absorbing the pressure and shock created when you move and put stress on them. A reduction in the normal amount of this cartilage tissue cause some forms of arthritis. Normal wear and tear causes OA, one of the most common forms of arthritis. An infection or injury to the joints can exacerbate this natural breakdown of cartilage tissue.Another common form of arthritis, RA, is an autoimmune disorder. It occurs when your body’s immune system attacks the tissues of the body. These attacks affect the synovium, a soft tissue in your joints that produces a fluid that nourishes the cartilage and lubricates the joints .RA is a disease of the synovium that will invade and destroy a joint. It can eventually lead to the destruction of both bone and cartilage inside the joint.
In rheumatoid arthritis, the body’s immune system attacks its own cells , including joints. If issue persists further it can attack internal organs functions. An inflammatory response occur when the immune system goes into action without an injury or infection to fight. Since there’s nothing to heal, the immune system cells that normally protect us begin to destroy healthy arteries, organs and joints. Joint pain from rheumatoid arthritis is caused by the inflammation present in a joint when the disease is active. Joint pain can also occur when the disease is inactive or controlled if the joint has been damaged by rheumatoid arthritis in the past. Active rheumatoid arthritis flare-ups cause the joint to swell because of both thickening of the joint lining tissue (synovium) and because of excess joint fluid. The swollen, inflamed joint stretches and irritates the capsule that surrounds the joint. The joint capsule has nerves endings within it that immediately send pain signals to the brain.
Past rheumatoid arthritis can lead to permanent joint destruction with damaged cartilage, bone, and ligaments. When the damaged joint is used, it can cause intense pain.
Inflammation if Left unchecked, it can contribute to chronic diseases, such as heart disease, blood vessel disease, diabetes, obesity, cancer, Alzheimer’s disease and other conditions. Immune system cells that cause inflammation contribute to the buildup of fatty deposits in the lining of the heart’s arteries. These plaques can eventually rupture, which causes a clot to form that could potentially block an artery. When blockage happens, the result is a heart attack.
