Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints but can also impact other parts of the body. The most common symptoms of RA include joint pain, stiffness, swelling, and reduced range of motion. These symptoms are often worse in the morning or after periods of inactivity. RA can lead to visible swelling and deformation of the joints, especially in the fingers and hands, if the inflammation is not effectively managed.
In addition to joint symptoms, RA can cause systemic symptoms like fatigue, fever, and loss of appetite. The inflammation characteristic of RA can affect various body parts, leading to a wide range of symptoms. For instance, reactive arthritis, a form of arthritis triggered by an infection elsewhere in the body, typically targets the knees, ankles, and feet. It can also affect the eyes, skin, and urethra.
Diagnosing RA often involves blood tests that look for markers of inflammation and autoimmunity, such as an elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, rheumatoid factor, and anti-cyclic citrullinated peptide (anti-CCP) antibodies. Imaging tests are also commonly used to assess the extent of joint damage.
Treatment for RA aims to manage symptoms and prevent joint damage. It may include medications, physical therapy, and in some cases, surgery. Understanding the symptoms and causes of RA is crucial for early diagnosis and effective management.
