Rheumatoid arthritis is an autoimmune disease that primarily affects the joints, causing inflammation, pain, and swelling. It occurs when the immune system mistakenly attacks the body's own tissues, particularly the lining of the joints. This condition can lead to joint damage and deformities over time, affecting mobility and quality of life.
Understanding rheumatoid arthritis is essential because it can significantly impact daily activities and overall health. The disease often leads to chronic pain and can affect other areas of the body, including the skin, eyes, and lungs. Early diagnosis and management are important to help minimize damage and maintain function.
In a healthy body, the immune system protects against infections and diseases. However, in rheumatoid arthritis, this system becomes confused and targets the joints, leading to inflammation and pain. This inflammatory response can cause the joint lining to thicken and create excess fluid, resulting in stiffness and discomfort.
Overall, rheumatoid arthritis is a complex condition that requires attention and care. It can vary in severity and may affect people differently. Awareness and understanding of this disease can help those affected to seek proper medical advice and support as needed.
