Description

Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes inflammation in the joints, resulting in pain, swelling, stiffness, and loss of function: Symptoms RA can cause pain, swelling, stiffness, tenderness, and heat in the joints. It can also affect other parts of the body, such as the eyes, mouth, and lungs. Joints affected RA can affect any joint, but it's most common in the hands, feet, and wrists. It often occurs in a symmetrical pattern, meaning that if one knee or hand is affected, the other is often also affected. Other symptoms RA can also cause fatigue, occasional fevers, and a loss of appetite. Complications RA can lead to serious complications, including heart, lung, or nervous system problems. Causes The causes of RA are unknown, but risk factors include smoking, obesity, and exposure to air pollution. Women and older people have a higher risk of developing RA. Treatments Treatments for RA include medicine, lifestyle changes, and surgery. Treatments can slow or stop joint damage and reduce pain and swelling. RA is different from osteoarthritis, the common arthritis that often comes with older age.
