According to the Centers for Disease Control (CDC), over 46 million adults suffer from arthritis, and almost 19 million adults have to curtail their activities due to arthritis. The CDC projects that, by the year 2030, 67 million adults will have arthritis and 25 million will limit their activities because of the condition.
Conditions and Causes
The two most common types of arthritis are osteoarthritis and rheumatoid arthritis. Osteoarthritis is a degenerative disease characterized by joint pain, and comes about as the result of and injury to or infection in the joint, or the aging process. Essentially, joint pain is caused by inflammation that arises when the cartilage that cushions the joints lessens.
In contrast to osteoarthritis, rheumatoid arthritis is an autoimmune condition that causes the immune system to attack and inflame the joints. Whereas osteoarthritis can be limited to a single, injured joint, or to a pair of joints (such as the knees or hips) in instances where the cartilage is worn out, rheumatoid arthritis usually affects multiple joints and can generally affects people at a much younger age.
