M05: Seropositive rheumatoid arthritis

M05.9: Seropositive rheumatoid arthritis, unspecified

Seropositive rheumatoid arthritis, unspecified, is a type of arthritis that is characterized by positive blood tests indicating the presence of specific autoantibodies in the body. This condition is classified as a type of autoimmune disease: the body's immune system mistakenly attacks its own healthy tissues, leading to inflammation mainly in the joints. Common symptoms include pain, swelling and stiffness in the joints, typically in the hands, wrists and feet. Over time, the inflamed joints may become damaged, affecting movement and function. It's important to note that the severity, course and nature of the disease can vary from person to person. While the exact cause of seropositive rheumatoid arthritis is unknown, factors such as genetics and environmental triggers are believed to play a role.
