Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that causes problems primarily in the joints, but can cause symptoms throughout the body. – See more at: http://www.healthline.com/health/rheumatoid-arthritis/effects-on-body

RA is a progressive autoimmune disease that mainly affects the joints. According to Arthritis Foundation, about 1.5 million people in the United States live with RA. Anyone can get RA, but it generally begins between the ages of 30 and 60. Women are diagnosed at almost three times the rate of men.
The cause of RA is unknown, but the National Institutes of Health (NIH) says that genetics, infections, or hormonal changes may play a role. Disease-modifying medications can help slow the progression of RA. Other medications, combined with lifestyle changes, can help manage individual symptoms and improve quality of life.
One of the first signs of RA is inflammation of the smaller joints in the hands and feet. Most of the time, symptoms on one side of the body correspond with symptoms on the other side of the body. Common symptoms include pain, swelling, tenderness, and stiffness, which is more pronounced in the morning. Some patients may feel a tingling or burning sensation. And symptoms can come and go in “flares” followed by a period of remission.
Symptoms can occur in any of the body’s joints, including shoulders, elbows, hips, knees, and ankles. People with RA often develop bunions, claw toes, or hammer toes. As the disease progresses, cartilage and bone are damaged and destroyed. Eventually, supporting tendons, ligaments, and muscles weaken. This can lead to a limited range of motion or difficulty moving the joints properly. In the long term, joints can become deformed.
Having RA also puts you at greater risk of developing osteoporosis, a weakening of the bones. People with osteoporosis are at increased risk of bone fractures and breaks. Chronic inflammation of the wrists can lead to carpal tunnel syndrome, making it difficult to use your wrists and hands. Weakened or damaged bones in the neck or cervical spine can cause chronic pain. X-rays can illuminate the extent of the damage.
RA can affect the system responsible for making and transporting blood throughout your body. A simple blood test can reveal the presence of an antibody called the rheumatoid factor. Not all people with the antibody develop RA, but it’s one of many clues doctors use to diagnose the condition.
People with RA have an elevated risk for developing anemia. This is due to a decrease red blood cell production. They also have a higher risk of blocked or hardened arteries. In rare cases, RA can lead to inflammation of the sac around the heart (pericarditis), the heart muscle (myocarditis), or even congestive heart failure.
A rare but serious complication of RA is inflammation of the blood vessels (rheumatoid vasculitis). Inflamed blood vessels weaken and expand or narrow, interfering with blood flow. This can lead to problems with the nerves, skin, heart, and brain.
Skin, Eyes, Mouth
Rheumatoid nodules are hard lumps caused by inflammation that appear under the skin, usually near joints. They can be a troubling, but usually aren’t painful.
As many as four million people in the United States have an inflammatory disease called Sjogren’s syndrome, according to theSjogren’s Syndrome Foundation. About half of those people also have RA or a similar autoimmune disease. When the two diseases are present, it’s called secondary Sjogren’s syndrome.
Sjogren’s causes severe dryness—especially of the eyes. Patients describe it as a burning or gritty feeling. Prolonged dry eyes increase the risk of eye infection or corneal damage. It’s rare, but RA can cause inflammation of the eye.
Sjogren’s can also cause dry mouth and throat, making it difficult to eat or swallow, especially dry foods. Chronic dry mouth can lead to tooth decay, gingivitis, and oral infections. Some patients experience swollen glands in the face and neck, dry nasal passages, and dry skin. Women may also feel dryness in their vaginas.
RA increases the risk of inflammation or scarring of the linings of the lungs (pleurisy) and damage to lung tissue (rheumatoid lung). Other problems include blocked airways (bronchiolitis obliterans), fluid on the chest (pleural effusions), high blood pressure in the lungs (pulmonary hypertension), scarring of the lungs (pulmonary fibrosis), or nodules on the lungs.
Although RA can damage the respiratory system, not everyone has symptoms. Those who do may experience shortness of breath, coughing, and chest pains.
The Immune System
Your immune system acts as an army, protecting you from harmful substances like viruses, bacteria, and toxins. It does this by producing antibodies to attack these invaders. Occasionally, the immune system mistakenly identifies a healthy part of the body as a foreign invader. When that happens, antibodies attack healthy tissue.
In RA, the joints are under attack. The result is intermittent or chronic inflammation throughout the body. Autoimmune diseases are chronic and treatment generally focuses on slowing progression and easing symptoms. Some people have more than one autoimmune disorder.
The pain and discomfort of RA can make it difficult to sleep. Many people with RA feel overwhelming fatigue and a lack of energy. In some cases, RA flare-ups cause short-term fever. Lack of appetite and lack of exercise can contribute to poor overall health.
Early diagnosis and treatment may help slow the progression of the disease. Disease-modifying medications, symptom relievers, and lifestyle changes can greatly improve the quality of life for people with RA.
