A shooting pain in knee. A burning sensation in hand. Before you know it, you have rheumatoid arthritis. Rheumatoid arthritis is a chronic inflammation of joints. Rheumatoid arthritis is an autoimmune disease in which immune system attacks normal tissues as if they were invading antibodies. Rheumatoid arthritis also causes inflammation of tissues around joints and other organs of body. The hands and feet are most affected areas of rheumatoid arthritis although it can also affect any joint lined by a membrane. Rheumatoid arthritis is referred to as a systematic illness and sometimes called rheumatoid disease.
Rheumatoid arthritis manifests itself over a period of a few months. However, for some, disease appears overnight. Accelerated onset of rheumatoid arthritis does not mean individual is at greater risk of progression of disease. Rheumatoid arthritis can lasts for years without symptoms. But rheumatoid arthritis is an illness that progresses and has potential to cause joint destrution and functional disability. Usually, patients suffer cycles from severe to light symptoms. In terms of statistics, rheumatoid arthritis is three times more common in women than in men. It also besets people of all races equally. Rheumatoid arthritis can begin at any age but most often start in early forties.
What causes rheumatoid arthritis? The truth is, its cause is still unknown. Viruses, bacteria, and fungi have long been suspected but none has been proven to be cause. The cause of rheumatoid arthritis has been focus of different research activities. There are some scientists who believe that tendency to develop rheumatoid arthritis may be genetically inherited while others believe that certain factors in environment might elicit immune system to attack body's own tissue components. This attack results to inflammation in various organs such as lungs or eyes.
Researchers have also found that environmental factors may also play a role in cause of rheumatoid arthritis. In fact, scientists reported that smoking tobacco increases risk in development of rheumatoid arthritis.
The symptoms of rheumatoid arthritis depend on degree of tissue inflammation. Rheumatoid arthritis is said to be active if body tissues are inflammed. When tissue inflammation subsides, rheumatoid arthritis is said to be in remission. Remissions may happen spontaneously or with treatment and can last for weeks, months, even years. During active rheumatoid arthritis, symptoms are felt. Symptoms may include fatigue, lack of appetite, low grade fever, and muscles and joint aches. Muscles and joint stiffness are usually felt during mornings and after a period of inactivity. During relapses (from inactivity to activity) of rheumatoid arthritis, joints become red, swollen, painful, and tender. This happens because tissue lining of joints become inflamed which results in excess production of joint fluids.
