Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints but can also damage a wide variety of body systems. Unlike the wear-and-tear damage of osteoarthritis, RA is an autoimmune condition where the immune system attacks the lining of the joints.
Overview
Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints but can also damage a wide variety of body systems. Unlike the wear-and-tear damage of osteoarthritis, RA is an autoimmune condition where the immune system attacks the lining of the joints.
This condition typically causes painful swelling that can eventually lead to bone erosion and joint deformity. While the inflammation can affect other organs, the hands, wrists, and feet are often the first areas to show symptoms. Early assessment and aggressive treatment are essential for preventing permanent disability.
Understand this condition
The body's immune system, which normally fights infections, attacks the synovium which is the lining of the membranes that surround your joints. The resulting inflammation thickens the synovium, which can eventually destroy the cartilage and bone within the joint. Tendons and ligaments that hold the joint together also weaken and stretch.
Why it happens
RA occurs when the body loses its ability to distinguish between its own cells and foreign invaders. This process is often triggered by a combination of genetic predisposition and environmental factors like smoking or gum disease. Over time, the continuous inflammation results in permanent scarring and joint misalignment.
Real-world scenarios
- •People may notice stiff fingers and toes every morning for weeks.
- •This often appears as symmetrical pain in both wrists or knees.
- •A person might feel unusually tired and run a low-grade fever.
- •Initial symptoms may include firm lumps under the skin near joints.
Common vs serious explanations
- •Normal age-related wear and tear called osteoarthritis.
- •Temporary joint strain from overexertion or exercise.
- •Tendinitis or bursitis from repetitive movements.
- Septic arthritis, which is a dangerous joint infection.
- Systemic lupus erythematosus, another complex autoimmune disease.
- Lyme disease, which can cause severe joint swelling.
Symptoms
Click any symptom to analyzeCauses

- •An overactive immune response causing chronic inflammation.
Risk factors
- •Family history of rheumatoid arthritis
- •Female sex (women are more likely to develop RA)
- •Smoking cigarettes significantly increases the risk
- •Age, most commonly beginning between 40 and 60
- •Obesity or being overweight
