Rheumatoid arthritis is an autoimmune disease that primarily affects the joints, causing chronic inflammation. The most common symptoms of rheumatoid arthritis include joint pain, stiffness, and swelling, often affecting multiple joints on both sides of the body. Morning stiffness that lasts for more than an hour is also a characteristic symptom of this condition. Fatigue, loss of appetite, and a general feeling of malaise are often experienced by individuals with rheumatoid arthritis. In some cases, the disease can also affect other parts of the body, leading to symptoms such as inflammation of the eyes, lung complications, and numbness or tingling in the extremities. Early diagnosis and appropriate treatment are essential to manage the symptoms and prevent joint damage.
