Arthritis is a term often used to mean any disorder that affects joints.[2]Symptoms generally include joint pain and stiffness.[2] Other symptoms may include redness, warmth, swelling, and decreased range of motion of the affected joints.[2][3] In some types of arthritis, other organs are also affected.[7] Onset can be gradual or sudden.[6]
Treatment may include resting the joint and alternating between applying ice and heat.[7][13] Weight loss and exercise may also be useful.[7][14] Recommended medications may depend on the form of arthritis.[15][9] These may include pain medications such as ibuprofen and paracetamol (acetaminophen).[9] In some circumstances, a joint replacement may be useful.[7]
Osteoarthritis affects more than 3.8% of people, while rheumatoid arthritis affects about 0.24% of people.[16] Gout affects about 1–2% of the Western population at some point in their lives.[17] In Australia about 15% of people are affected by arthritis,[18] while in the United States more than 20% have a type of arthritis.[12][19] Overall the disease becomes more common with age.[12] Arthritis is a common reason that people miss work and can result in a decreased quality of life.[9] The term is derived from arthr- (meaning 'joint') and -itis (meaning 'inflammation').[20][21]
