Arthritis starts when the protective cartilage that covers the ends of the bones wears down. This can be caused by aging, overuse of joints, injury, obesity, diet, and autoimmune disorders. When the cartilage wears away, bones start to rub together, leading to arthritis symptoms of inflammation and pain.
As the disease progresses, the inflammation can cause the joints to swell, stiffen and become painful. The body forms extra bone in an attempt to repair the damage, which can lead to further pain, joint deformity, and reduced mobility.
The most common limbs affected by arthritis are the hands, elbows, wrists, shoulders, hips, knees, ankles, and feet. These areas often experience pain and stiffness, which can make it difficult to perform everyday activities. Arthritis can also limit the person's ability to perform activities and complete tasks.
