Rheumatoid Arthritis: Understanding a Chronic Autoimmune Disease
Rheumatoid arthritis (RA) is a chronic autoimmune disorder that primarily affects the joints of the body but can also involve other organs and systems of the body as well. Unlike osteoarthritis, which results from wear and tear, rheumatoid arthritis occurs when the immune system mistakenly attacks healthy tissues, leading to inflammation, pain, and progressive joint damage. RA affects millions of people worldwide and can significantly impact quality of life if not responsibly managed.
