Rheumatoid arthritis (RA) is a chronic inflammatory disorder that significantly impacts various body systems, including the joints, skin, eyes, lungs, heart, and blood vessels. It is characterized by pain, swelling, and potentially severe damage. RA is an autoimmune and inflammatory disease, primarily affecting the joints and other tissues. The disease is known for causing joint inflammation and pain, particularly when the immune system attacks the lining of the joints, known as the synovium. Commonly affected areas include the hands, knees, or ankles, and it usually impacts the same joint on both sides of the body, such as both hands or both knees.
The cause of RA remains unknown, but it is recognized as an autoimmune condition where the body’s immune system mistakenly targets healthy tissue. It can lead to inflammation of the joints and surrounding tissues and can also affect other organs. Although RA can occur at any age, it often starts in middle age and is more prevalent in older individuals, with a higher incidence in women than men.
The inflammation caused by RA can be severe, affecting how the joints and other parts of the body look and function. In the hands, for example, RA can cause deformities in the joints of the fingers, leading to difficulty in hand movements.
To better understand RA, it is helpful to learn common medical terms related to the condition, such as acute pain, arthritis, enthesitis, and rheumatoid factor. These terms are essential for comprehending RA symptoms, diagnosis, treatment, and prevention strategies.
