While arthritis is usually associated with older people, Juvenile Arthritis affects children under 16 and is an autoimmune condition. This means the child’s immune system, which normally fights infections, starts attacking the body’s healthy joints, causing pain, swelling, stiffness, and fatigue. It may be due to a combination of genetics and environmental triggers, such as certain infections. Juvenile Arthritis is not caused by injury or overuse, and it is not contagious. Some children may have a family history of autoimmune diseases, which can slightly increase the risk. Early signs like morning stiffness, limping, joint swelling, or unexplained fatigue are often confused with growing pains. But if these symptoms last more than a couple of weeks, consult a doctor. With timely diagnosis and the right care, children with Juvenile Arthritis can lead happy, active lives.
