What Is Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic autoimmune disease in which the body's immune system mistakenly attacks the synovial lining of joints. This causes inflammation, pain, swelling, and stiffness throughout the body. Unlike osteoarthritis, which results from wear and tear over time, rheumatoid arthritis develops when the immune system malfunctions. RA typically affects multiple joints simultaneously and can develop relatively quickly over weeks or months.

Symptoms and Signs

Common symptoms of rheumatoid arthritis include:

• Joint pain, swelling, and warmth, especially in hands, wrists, feet, and knees
• Morning stiffness lasting more than one hour
• Fatigue and general feeling of illness
• Fever and loss of appetite
• Symmetrical joint involvement affecting both sides of the body

Symptoms often develop gradually over weeks or months. Early diagnosis and treatment are crucial to prevent irreversible joint damage.

Causes and Risk Factors

The exact cause of rheumatoid arthritis is not fully understood, but several factors contribute to its development. Genetics play a significant role; people with certain genes like HLA-DR4 are at higher risk. Environmental triggers such as infections, smoking, and stress may activate the disease. Women are two to three times more likely than men to develop RA. Age of onset is typically between 40 and 60, though it can occur at any age.

Treatment and Management

Modern treatment focuses on slowing disease progression and managing symptoms effectively. Disease-modifying antirheumatic drugs (DMARDs) are the cornerstone of therapy, reducing inflammation and preventing joint damage. Biologic therapies target specific parts of the immune system. NSAIDs manage pain and inflammation. Physical therapy and exercise maintain joint function and mobility. Early and aggressive treatment significantly improves outcomes and quality of life.

Complications and Long-Term Outlook

Without treatment, rheumatoid arthritis can lead to permanent joint deformity and disability. However, modern treatments have dramatically improved outcomes. Many patients achieve remission or low disease activity. RA can also affect other organs including the lungs, heart, and eyes, requiring comprehensive medical management. Regular monitoring and treatment adjustments help manage the disease effectively.
