The disease also can affect other parts of the body. Arthritis causes pain, loss of movement and sometimes swelling. Some types of arthritis are:

• Osteoarthritis, a degenerative joint disease in which the cartilage that covers the ends of bones in the joint deteriorates, causing pain and loss of movement as bone begins to rub against bone. It is the most prevalent form of arthritis.
• Rheumatoid arthritis, an autoimmune disease in which the joint lining becomes inflamed as part of the body’s immune system activity. Rheumatoid arthritis is one of the most serious and disabling types, affecting mostly women.
• Gout, which affects mostly men. It is usually the result of a defect in body chemistry. This painful condition most often attacks small joints, especially the big toe. Fortunately, gout almost always can be completely controlled with medication and changes in diet.
• Ankylosing spondylitis, a type of arthritis that affects the spine. As a result of inflammation, the bones of the spine grow together.
• Juvenile arthritis, a general term for all types of arthritis that occur in children. Children may develop juvenile rheumatoid arthritis or childhood forms of lupus, ankylosing spondylitis or other types of arthritis.
• Systemic lupus erythematosus (lupus), a serious disorder that can inflame and damage joints and other connective tissues throughout the body.
• Scleroderma, a disease of the body’s connective tissue that causes a thickening and hardening of the skin.
• Fibromyalgia, in which widespread pain affects the muscles and attachments to the bone. It affects mostly women.
