Arthritis

Arthritis refers to joint inflammation and includes common types like osteoarthritis and rheumatoid arthritis. Osteoarthritis results from cartilage breakdown due to aging or wear-and-tear, while rheumatoid arthritis is an autoimmune condition that causes the immune system to attack the joints. Both forms can lead to chronic pain, stiffness, and reduced mobility if left untreated.
