Overview
A clear starting point
Rheumatoid arthritis (RA) is a chronic autoimmune disease in which the immune system mistakenly attacks the body's own tissues, primarily affecting the joints. This causes inflammation, leading to pain, swelling, stiffness, and potential loss of function, most commonly in the hands, wrists, and knees. Over time, untreated RA can cause severe joint damage and may also affect other systems, including the heart, lungs, and eyes. While the exact cause remains unknown, genetics and environmental factors like smoking play a role. Although there is no cure, early diagnosis and disease-modifying treatments can effectively manage symptoms, slow progression, and help individuals maintain their independence and quality of life.
Four key facts
- 1Rheumatoid arthritis is an autoimmune disease where the immune system attacks joint tissues, causing chronic inflammation.
- 2The condition often affects joints symmetrically, meaning if one hand or knee is affected, the other usually is too.
- 3Women are two to three times more likely to develop rheumatoid arthritis than men.
- 4Smoking is a significant risk factor that can increase the likelihood of developing the disease and worsen its severity.
Useful points to discuss
When professional care may be important
These examples are not a diagnosis checklist. New, severe, rapidly worsening, or concerning symptoms should be assessed by a qualified healthcare professional; emergencies require local emergency services.
- Noticeable joint swelling, redness, or warmth that persists for several days.
- Joint stiffness that lasts longer than 30 minutes, particularly after waking up in the morning.
- Experiencing sudden worsening of symptoms, known as a flare, which may include fever or unexplained fatigue.
