Rheumatoid arthritis is a chronic autoimmune disease characterized by systemic damage to multiple joints with an unclear cause. Thus, it cannot be cured, meaning it cannot be completely healed. Treatment can only alleviate joint pain and morning stiffness through medication, delay the onset of complications, reduce bone damage, decrease disability rates, and improve quality of life. This is the comprehensive purpose of treatment. Therefore, early diagnosis and standardized treatment of this disease are essential to prevent joint deformities and to maintain quality of life.
