What is Rheumatoid Arthritis?
Rheumatoid arthritis (RA) is the result of an autoimmune system gone away. In RA, the immune system mistakenly attacks the joints causing pain and inflammation, that causes the tissue that lines the inside of joints (the synovium) to thicken, resulting in swelling and pain in and around the joints.
Rheumatoid Arthritis is a chronic disease, the common symptoms are joint pain, stiffness, swelling and decreased movement of the joints. Rheumatoid arthritis most commonly affects the joints of the hands, feet, wrists, elbows, knees, and ankles. If not treated well, rheumatoid arthritis will produce the joint symmetrical effect. That means if one knee or hand if affected, usually the other one is, too. Because RA also can affect body systems, such as the cardiovascular or respiratory systems, so it is called a systemic disease.
What is Rheumatoid Arthritis Causes?
The cause of RA is not known, the relevant Research suggests that people with certain variations of human leukocyte antigen (HLA) genes have an increased risk of developing RA.
But not everyone with these identified gene variants develops RA, and people without them can still develop it. So it's likely that other environmental factors often trigger the disease, particularly in people with a genetic makeup that makes them more susceptible to it. These factors include:
- Viruses and bacteria
- Female hormones
- Exposure to certain kinds of dust and fibers
- Obesity
- Severely stressful events
- Smoker
- With a family history of RA
