Rheumatoid arthritis is a chronic autoimmune disease that primarily affects the joints. In this condition, the body's immune system mistakenly attacks the synovium, the lining of the joints, leading to inflammation, pain, and swelling. Over time, this can cause joint damage and loss of function, making everyday activities challenging for those affected. People with rheumatoid arthritis may experience symptoms like stiffness, especially in the morning, and fatigue. While there is no cure, treatments such as medications and physical therapy can help manage symptoms and improve quality of life. Early diagnosis and intervention are crucial for better outcomes in individuals with this condition.
