Rheumatoid Arthritis

A chronic inflammatory disorder that occurs when the immune system attacks the synovium, the lining of membranes surrounding the joints. Most often affects the small joints in the hands and feet, causing a painful swelling that can result in bone erosion and joint deformity.

Common causes:

  • Genetic component can cause susceptibility toward infections with certain viruses and bacteria

Risk Factor:

  • Gender - women are at higher risk
  • Age - most common between the ages of 40 and 60
