Juvenile Idiopathic Arthritis (JIA) is a type of arthritis that affects children and adolescents. It causes inflammation in the joints, leading to pain, swelling, and stiffness. The exact cause of JIA is unknown, but it is believed to involve a combination of genetic and environmental factors. Symptoms can vary and may include fatigue, fever, and growth issues. There are several subtypes of JIA, each with different characteristics and treatment approaches. Early diagnosis and management are crucial to prevent long-term joint damage and improve the quality of life for affected children. Treatment often includes medications, physical therapy, and regular monitoring by healthcare professionals.
