Rheumatoid Arthritis (RA) is an autoimmune disorder where the immune system mistakenly attacks the synovium, the lining of the membranes that surround the joints. This chronic inflammatory condition primarily affects the joints but can also involve other organs and systems.

• Genetics: Family history of RA increases the risk.
• Autoimmune Response: Immune system dysfunction leads to inflammation in the joints.
• Environmental Factors: Such as smoking, infection, and hormonal changes.
• Gender: Women are more likely to develop RA than men.
