Rheumatoid arthritis (RA) affects approximately 1% of the global population, with higher prevalence in women and older adults (World Health Organization). This chronic autoimmune disorder primarily targets the joints, but also involves the immune system, leading to pain, swelling, and progressive joint damage.
