Arthritis is a common medical condition that affects the joints, causing pain, stiffness, and inflammation. It is a broad term used to describe over 100 different types of joint diseases, with the two most prevalent forms being osteoarthritis and rheumatoid arthritis. Osteoarthritis is characterized by the gradual wear and tear of the cartilage that cushions the joints. It commonly affects older individuals and can be caused by aging, joint injuries, or obesity. As the cartilage deteriorates, the bones in the joint may rub against each other, resulting in pain, swelling, and reduced mobility. On the other hand, rheumatoid arthritis is an autoimmune disorder where the body’s immune system mistakenly attacks the joints. It primarily affects the lining of the joints, causing inflammation, pain, and eventual joint deformity. Unlike osteoarthritis, rheumatoid arthritis can affect people of any age. Arthritis symptoms can vary from mild to severe and can impact various joints in the body, including the hands, knees, hips, and spine. In addition to joint pain and stiffness, individuals with arthritis may experience fatigue, reduced range of motion, and difficulty performing everyday tasks.
