What is Rheumatoid Arthritis?
Arthritis also is the leading cause of disability. Nearly 7 million people in the U.S., including 20% of people with arthritis, are unable to perform major life activities such as working or housekeeping because of this disease. Arthritis sufferers endure more days in severe pain, experience more days with limited ability to perform daily activities, and have more difficulty performing personal-care routines than people without arthritis. As with other chronic pain conditions, arthritis has negative effects on mental health. Some forms of arthritis also make your RealAge older.
The Definition of Rheumatoid Arthritis
Rheumatoid arthritis, known as Still’s disease when it affects children, is a condition that causes inflammation of joints and associated pain, swelling, and stiffness. Rheumatoid arthritis causes the body’s own immune system to attack joint tissue, breaking down collagen, cartilage, and sometimes bone or other organs. This chronic disease varies between people and fluctuates over time, often marked by symptoms that improve only to re-emerge later. In some cases rheumatoid arthritis is mild and lasts only a few months (this kind of rheumatoid arthritis is called type 1), while in others the disease becomes progressively complicated by disability and other health problems, lasting many years (this is called type 2 rheumatoid arthritis).

Rheumatoid arthritis most often affects the wrist and finger joints closest to the hand, but can also affect joints in the feet and throughout the body. Anyone can be affected by rheumatoid arthritis, but women are more likely to develop symptoms, which most often begin between the ages of 20 and 30. The causes of rheumatoid arthritis are not yet understood, but many effective strategies have been developed to manage its symptoms.
Rheumatoid Arthritis Symptoms and Signs
The main symptom of rheumatoid arthritis is joint stiffness in the morning, often in the hands or feet. Stiffness that persists for an hour or more, or swelling and pain that lasts for more than six weeks, may be indicative of rheumatoid arthritis. Joint discomfort is typically symmetrical, i.e. both hands will hurt or feel stiff, not just one. Early rheumatoid arthritis symptoms also may include fever, excessive tiredness, or pea-sized lumps called “nodules” that can be felt under the skin.
