What Is Arthritis, Exactly?

What is arthritis? Arthritis is an umbrella term for over 100 conditions. The most common form of arthritis is osteoarthritis, or degenerate joint disease. The causes of osteoarthritis include inflammation, mechanical stress, and genetics. It typically involves pain and discomfort in the joints and over time this condition can lead to joint weakness and physical deformities, which can interfere with even the most basic daily activities like walking, typing or cutting your food. In this video, Dr. Holly Atkinson explains how a healthy body works, what some arthritis risk factors are, and what happens when your joints are inflicted with arthritis. She explains that osteoarthritis occurs when cartilage degenerates and the bony ends of your joints are left unprotected. This causes them to rub together when moving, thus causing pain and inflammation.
