** This entry is about **Rheumatoid Arthritis (RA)**, a chronic autoimmune disorder that causes inflammation and pain in the joints. **CONTENT:** ## Overview Rheumatoid Arthritis (RA) is a complex and debilitating condition that affects millions of people worldwide. It is a chronic autoimmune disorder, meaning that the body's immune system mistakenly attacks the lining of the joints, leading to inflammation, pain, and stiffness. RA can affect any joint in the body, but it most commonly affects the hands, wrists, knees, ankles, and feet. The symptoms of RA can vary from person to person, but they often include joint pain, swelling, and stiffness, as well as fatigue, fever, and loss of appetite. If left untreated, RA can lead to permanent joint damage and disability. RA is a chronic condition, meaning that it cannot be cured, but it can be managed with treatment. The goal of treatment is to reduce symptoms, slow disease progression, and improve quality of life. Treatment options for RA include medication, physical therapy, and lifestyle changes. Medications used to treat RA include disease-modifying antirheumatic drugs (DMARDs), biologics, and corticosteroids. Physical therapy can help improve joint mobility and strength, while lifestyle changes such as maintaining a healthy weight, exercising regularly, and getting enough sleep can also help manage symptoms. ## History/Background Rheumatoid Arthritis has been described in medical literature for centuries. The Greek physician Galen described a condition similar to RA in the 2nd century AD. However, it wasn't until the 19th century that RA was formally described as a distinct medical condition. In the early 20th century, the discovery of the role of the immune system in RA led to the development of new treatments, including DMARDs. In the 1990s, the introduction of biologics revolutionized the treatment of RA, offering new hope for people with the condition. ## Key Information * **Prevalence:** RA affects approximately 1% of the global population, with women being more likely to develop the condition than men. * **Causes:** The exact cause of RA is unknown, but it is believed to be a combination of genetic and environmental factors. * **Symptoms:** Common symptoms of RA include joint pain, swelling, and stiffness, as well as fatigue, fever, and loss of appetite. * **Treatment:** Treatment options for RA include medication, physical therapy, and lifestyle changes. * **Complications:** Untreated RA can lead to permanent joint damage and disability. ## Significance Rheumatoid Arthritis is a significant public health concern, affecting millions of people worldwide. It is a leading cause of disability and lost productivity, and it has a significant impact on quality of life. The economic burden of RA is also substantial, with estimates suggesting that it costs the global economy billions of dollars each year. However, with advances in treatment and management, people with RA can lead active and fulfilling lives. **INFOBOX:** - Name: Rheumatoid Arthritis (RA) - Type: Chronic autoimmune disorder - Date: First described in medical literature in the 2nd century AD - Location: Affects people worldwide - Known For: Being a leading cause of disability and lost productivity **TAGS:** Rheumatoid Arthritis, autoimmune disorder, chronic condition, joint pain, inflammation, disease-modifying antirheumatic drugs (DMARDs), biologics, corticosteroids, physical therapy, lifestyle changes, public health concern, disability, lost productivity, quality of life, economic burden.
