What is Rheumatoid Arthritis?

If you watch prime time TV, you have probably seen the many commercials for rheumatoid arthritis treatments. But maybe you need more detailed information?

Rheumatoid arthritis is a chronic (long-term) disease that causes inflammation of the joints and surrounding tissues. It can also affect other organs. Usually rheumatoid arthritis afflicts the joints on both sides of the body equally. The wrists, fingers, knees, feet, and ankles are most commonly involved. Patients may experience low-grade fevers, fatigue, and weakness, as well.

What Causes Rheumatoid Arthritis?

The exact cause of rheumatoid arthritis (RA) is unknown. It is considered an autoimmune disease; that is, a disease where the body's immune system, which normally fights off foreign substances such as a virus or bacteria, instead confuses healthy tissue for a foreign substance. This leads the body to set up an attack on itself - at the joints where RA occurs. Genetics and family history may also play a part. Learn more about autoimmune diseases here.

Joint and bone destruction can occur over time if the disease process is not well-controlled.

Who Gets Rheumatoid Arthritis?

Maybe you've seen the pictures of the twisted joints in the hands of older people, and think rheumatoid arthritis is simply a disease of the elderly. But rheumatoid arthritis can occur at any age but it is usually seen in people between the ages of 25 and 55. Women are affected 2 to 3 times more often than men. Rheumatoid arthritis can even occur in juveniles.

The course and severity of the illness can vary considerably. Infection, genetics, and hormones may all contribute to the development of the disease. Roughly 1 out of 100 American adults (1%) have rheumatoid arthritis, and currently there is no cure.

What Are the Symptoms of Rheumatoid Arthritis?

We all have moments when our joints ache or our muscles feel tired. But rheumatoid arthritis usually begins gradually with symptoms such as:

  • fatigue
  • morning stiffness (lasting more than one hour)
  • widespread muscle aches
  • loss of appetite
  • weakness.

Eventually, joint pain appears. When the joint is not used for a while, it can become warm, tender, and stiff. When the lining of the joint (synovium) becomes inflamed, it gives off more fluid and the joint becomes swollen. Joint pain is often felt on both sides of the body, and may affect the wrist, knees, elbows, fingers, toes, ankle or neck. Nonjoint structures can also be affected such as the eyes, skin, lungs, heart, or blood vessels.

How is Rheumatoid Arthritis Diagnosed?

Rheumatoid arthritis is diagnosed based on the results of joint x-rays and a rheumatoid factor test (which is positive in about 75% of people with symptoms).

In addition, the erythrocyte sedimentation rate is elevated and the complete blood count (CBC) may show low hematocrit (anemia) or abnormal platelet counts.

A C-reactive protein test may also be positive for patients with no detectable rheumatoid factor and synovial fluid analysis may be used to diagnose the cause of pain and swelling in joints.

How is Rheumatoid Arthritis Treated?

Rheumatoid arthritis usually requires lifelong treatment with medications, physical therapy, exercise, education, and possibly surgery.

Early, aggressive treatment of rheumatoid arthritis can delay joint destruction. Rheumatoid arthritis is a disease with a variable prognosis that can impair the quality of life.

Drug treatment options for rheumatoid arthritis have advanced significantly in recent years - a summary of some of the options available can be found here in the slideshow "Drug Treatment of Rheumatoid Arthritis".

Quality of Life With Rheumatoid Arthritis

Sure, being diagnosed with RA is life changing but it needn't be a life sentence. The stresses of completing simple tasks while juggling family life and work commitments can be a daunting prospect. Adjustment to a new routine is certainly not easy but rest assured, you're not alone.

Getting medical help and treatment is important, but so is helping yourself. Be sure to learn about range-of-motion exercises and stay active, too. Consider joining the Drugs.com Rheumatoid Arthritis Support group to stay up-to-date with the latest news and approvals, ask questions, and voice your concerns, too.
