Arthritis is a general term that is used to describe inflammation (pain and swelling) of the joints in the body. Rheumatoid arthritis (RA) is a type of chronic arthritis that occurs in varying joints such as the hands, wrists or knees and will appear in the joints on both sides of the body at the same time. This appearance of the inflammation on both sides of the body (such as both knees, or both wrists) is one way of identifying RA from other types of arthritis (there are more than 150 different types of arthritis). In addition to affecting the joints, RA is known to affect organs of the body including the skin, eyes, lungs, heart, blood and kidneys.
Unlike osteoarthritis, rheumatoid arthritis is an inflammatory disease that can affect people of all ages. It usually starts slowly and often begins in small joints, such as in the fingers. It may begin in just one joint, but will eventually affect several joints, often simultaneously. Also, there are often other symptoms, such as fatigue, having fevers, losing weight, and vague aches and pains. Some people may suffer from only one attack of this disease in their lives. In others, the disease may be long-term and progressive and in some it may progress rapidly.
Rheumatoid arthritis is 3 times more common in women than men and usually begins in people aged from 20-50 years. However, young children and the elderly can also develop the condition.
The cause of rheumatoid arthritis is not fully understood. However, it is thought to be caused by a combination of genetic, environmental and hormonal factors.
There are a number of different ways to diagnose rheumatoid arthritis, with diagnosis usually decided by considering a combination of the following:
However, a balance of rest and exercise is important. When there is a worsening of the joint inflammation, rest is indicated and you may need to use a walking cane or joint splints. When the inflammation decreases, gentle exercise is needed to maintain mobility in the joint and to strengthen the surrounding muscles.
Although there is not yet a cure for rheumatoid arthritis, with the help of your doctor, you can manage it by taking steps to decrease the pain and inflammation of the condition. Current evidence suggests that early aggressive treatment of rheumatoid arthritis may improve the long-term outcome.
