What is rheumatoid arthritis?

Rheumatoid arthritis is a chronic autoimmune disease that causes inflammation in the joints, resulting in pain, swelling, stiffness, and decreased mobility. It primarily affects the joints, but can also affect other organs and systems in the body. Over time, rheumatoid arthritis can cause joint damage and deformities. It is a progressive disease with no cure, but treatment options are available to help manage symptoms and slow the progression of the disease.

Rheumatoid arthritis (RA) is an autoimmune disease in which the body's immune system mistakenly attacks its own tissues, especially the synovial membrane that lines the joints. This attack causes inflammation, pain, swelling, and stiffness in the joints. RA can affect any joint in the body, but it most commonly affects the hands, feet, wrists, and knees.

RA is a chronic disease, meaning that it can last for many years. However, with early diagnosis and treatment, most people with RA can live full and active lives.
