What Is Rheumatoid Arthritis?
About 1.3 million Americans have been diagnosed with rheumatoid arthritis, making the disease the most common type of inflammatory arthritis. Approximately 75 percent of rheumatoid arthritis patients are women. Rheumatoid arthritis typically begins in middle age, but children and young adults can also develop the disease. People of all races and ethnic backgrounds can develop rheumatoid arthritis.
The exact cause of rheumatoid arthritis is still unknown, but researchers are gaining a better understanding of how the immune system and genetic factors affect the inflammatory processes that cause rheumatoid arthritis to develop. As researchers continue to work on the cause and cure for rheumatoid arthritis, it's important for you, the patient, to recognize the signs and symptoms of rheumatoid arthritis so you can:
- consult a rheumatologist
- get an accurate diagnosis
- develop an early treatment plan
Recognizing Rheumatoid Arthritis Symptoms
Rheumatoid arthritis usually develops gradually, but some patients experience sudden onset of symptoms: one day they are perfectly healthy and the next they are dealing with rheumatoid arthritis. Symptoms commonly associated with rheumatoid arthritis include:
- Morning stiffness that lasts one or more hours
- Symmetrical pattern of affected joints, meaning the same joint on both sides of the body is affected (e.g., both knees)
- Small joints of the hands and feet are characteristically involved, although any joint can be affected
- Rheumatoid nodules (firm lumps under the skin), found on elbows and hands of about one-fifth of rheumatoid arthritis patients
- Fatigue and noticeable loss of energy
- Low grade fevers and sometimes flu-like symptoms
- Loss of appetite, weight loss, anemia associated with chronic diseases, depression
- Joint deformity and instability from damage to cartilage, tendons, ligaments, and bone
- Limited range of motion in affected joints
- Rheumatoid arthritis may have systemic effects (i.e., affect the organs of the body)
No two rheumatoid arthritis cases are exactly the same. There is so much variety among the symptoms that some researchers suspect rheumatoid arthritis is not one disease but rather several diseases with commonalities.
- Don't ignore pain that persists.
- Don't assume you simply injured yourself.
- Consult a rheumatologist (a medical doctor who specializes in diagnosing and treating rheumatoid arthritis patients as well as those with other rheumatic diseases).
- When you consult your rheumatologist, always discuss symptoms that have improved or worsened, as well as any new symptoms.
