Over time, this inflammation may destroy the joint tissues. This can limit your daily activities and make it hard for you to walk and use your hands.
Rheumatoid arthritis is 2 to 3 times more common in women than in men. It often begins between the ages of 40 and 60.
What causes rheumatoid arthritis?
The exact cause of rheumatoid arthritis is not known. But rheumatoid arthritis is an autoimmune disease. This means that the body's natural defense system attacks the joints. The disease also runs in some families.
What are the symptoms?
The main symptoms of rheumatoid arthritis are pain, stiffness, and swelling in the joints of the hands, wrists, elbows, feet, ankles, knees, or neck. The disease usually affects both sides of the body at the same time. In rare but severe cases, it may affect the eyes, lungs, heart, nerves, or blood vessels.
Sometimes rheumatoid arthritis can cause bumps called nodules to form over the elbows, knuckles, spine, and lower leg bones.
How is rheumatoid arthritis diagnosed?
There is no single test for rheumatoid arthritis. Your doctor will look at your joints for signs of swelling or tenderness. He or she will also ask about your symptoms and past health.
You may have blood tests, X-rays, and other tests to find out if another problem is causing your joint pain.
