An autoimmune disease where the immune system attacks the joints, causing pain, swelling, stiffness, and potential joint damage.
Overview
Rheumatoid Arthritis (RA) is a chronic autoimmune disease in which the immune system attacks the synovium — the lining of the joints. This causes inflammation, pain, swelling, and if left untreated, permanent joint damage and deformity. RA most commonly affects the small joints of the hands and feet, typically symmetrically (both sides of the body). It can also cause systemic symptoms like fatigue, fever, and inflammation in other organs. RA affects about 1% of the population and is more common in women. While it most often develops between ages 30 and 60, it can affect children (Juvenile Idiopathic Arthritis) and young adults. Early diagnosis and treatment are critical to prevent irreversible joint damage.
Common Symptoms
Symptoms include: • Joint pain, swelling, and stiffness — especially in the hands, feet, and wrists • Morning stiffness lasting more than 30 minutes • Symmetric joint involvement (both sides of the body) • Fatigue and low-grade fever • Joint warmth and redness • Reduced range of motion • Nodules under the skin • Dry eyes and mouth (if Sjögren's overlaps) Symptoms can fluctuate, with periods of flare and remission.
Diagnosis
Diagnosis involves: • Medical history and physical exam • Blood tests (RF, anti-CCP antibodies, inflammatory markers) • Imaging (X-rays, ultrasound, MRI) • Assessment of joint involvement pattern Early diagnosis is important — damage can begin in the first months of disease.
Current Treatments
Treatment has been revolutionized by modern therapies: • DMARDs (disease-modifying antirheumatic drugs) — methotrexate is the cornerstone • Biologic medications (TNF inhibitors, IL-6 inhibitors, JAK inhibitors) • NSAIDs and corticosteroids for symptom relief • Physical and occupational therapy • Joint protection strategies • Lifestyle modifications (exercise, smoking cessation, healthy diet) Early, aggressive treatment can achieve remission in many patients.
Research Summary
RA research has led to major advances in treatment, particularly the development of biologics and targeted therapies. Ongoing studies explore personalized treatment, remission, and the prevention of joint damage. More research is needed on treatment-free remission and on RA in diverse populations.
Community Resources
RA has a large and active patient community. Advocacy organizations provide education, research updates, and support. Connecting with others who understand living with an autoimmune arthritis can be valuable. Explore our Stories page and community resources.
