Rheumatoid arthritis (RA) is a chronic autoimmune disorder that causes inflammation in the joints. It occurs when your immune system mistakenly attacks the synovium, the lining of the membranes that surround your joints. This leads to swelling, pain, and stiffness in the joints, as well as fatigue and loss of appetite.
RA can affect any joint in the body, although it is most commonly found in the hands, wrists, feet, ankles, and elbows. It can also affect other organs, such as the heart, lungs, and eyes. Symptoms of RA can vary from person to person, ranging from mild to severe.
The cause of RA is unknown, but genetics, environment, and hormones may play a role. Treatment usually includes medications to reduce inflammation, pain, and stiffness. Some people may need physical therapy or surgery to help keep their joints functioning.
RA is a serious condition, but it can be managed with proper treatment. If you have any questions or concerns, it's important to talk to your doctor.
