Despite popular belief, arthritis isn’t just one disease. “Arthritis” is a broad term that refers to more than 100 conditions that affect the joints (the place where bones connect). The most common types are:

  • Osteoarthritis (OA) is a form of the disease in which tissue that protects the ends of bones breaks down.
  • Rheumatoid arthritis (RA) is a form of the disease that causes the body’s immune system to attack the lining of the joints.

The end results for both OA and RA are the same for the most part – stiff, painful joints.

2. Arthritis isn’t just for “older” people
People of all ages have arthritis. In fact, children as young as one year old can get arthritis, and more than half of U.S. adults with arthritis are of working age (18 to 64 years). leaving site icon That being said, the chance of getting arthritis does grow as you get older.
