Rheumatoid arthritis (RA) is a complex condition that affects many people worldwide. But what exactly is it, and how does it manifest in the human body?
What is Rheumatoid Arthritis?
RA is an autoimmune and inflammatory disease. In simpler terms, it means that the body’s immune system mistakenly targets healthy cells, causing inflammation. This inflammatory response primarily affects the joints, but RA can impact a broader range of body systems as well. 
How Does RA Affect the Body?
In some individuals, RA can damage a wide variety of body systems including the skin, eyes, lungs, heart, and blood vessels. The condition’s primary target, however, remains the joints. It commonly affects joints in areas like the hands, wrists, and knees. Often, the same joint on both sides of the body, such as both hands or both knees, is impacted. Over time, the inflammation can be so severe that it leads to deformities, particularly noticeable in joints of the fingers.
What Causes RA?
RA is an autoimmune disorder. Under normal circumstances, our immune system defends us against threats like bacteria and viruses. However, in the case of autoimmune diseases like RA, the body erroneously sees its own tissues as threats and attacks them. This misguided immune response is what leads to the painful swelling and damage associated with RA.
Symptoms and Treatment
Symptoms of RA include joint inflammation, pain, swelling, stiffness, and loss of joint function. The lining of the joints, known as the synovium, gets attacked when the immune system doesn’t function correctly. There are treatments available that can help manage these symptoms and reduce the impact of the disease on daily life. If you or someone you know is experiencing symptoms resembling RA, it’s essential to seek professional medical advice.
In conclusion, understanding rheumatoid arthritis is crucial, not just for those who suffer from it but also for those around them. Knowledge can lead to empathy, better care, and more effective treatments.
