Arthritis

What is arthritis?

Typically, pain, aching, stiffness and swelling in and around one or more joints characterize rheumatic conditions. The symptoms can develop gradually or suddenly. Certain rheumatic conditions can also involve the immune system and various internal organs of the body.⁶

The term “arthritis” is used to describe numerous rheumatic diseases and conditions that affect joints.

Some forms of arthritis, such as rheumatoid arthritis and lupus, can affect multiple organs and cause widespread symptoms.

Arthritis is more common among adults aged 65 years or older, but people of all ages (including children) can be affected.

There is no one cause for arthritis; the cause depends on the type or form of arthritis. Potential causes for arthritis may include:

• Injury – leading to degenerative arthritis
• Abnormal metabolism – leading to gout and pseudogout
• Inheritance – such as in osteoarthritis
• Infection
