Arthritis is a common condition that causes pain and inflammation within a joint. The condition affects people of all ages including children. Although arthritis is often associated with older people, it can sometimes affect children. Most types of childhood arthritis are referred to as juvenile idiopathic arthritis (JIA). JIA causes pain and inflammation in one or more joints for at least six weeks. Although the exact cause of JIA is unknown, the symptoms often improve as a child gets older, allowing them to lead a normal life.
Type - It is divided into two types:
Osteoarthritis - Osteoarthritis is the most common form of arthritis. In people affected by osteoarthritis, the cartilage (connective tissue) between their bones gradually wastes away, leading to painful rubbing of bone on bone in the joints. The most frequently affected joints are in the hands, spine, knees and hips. Osteoarthritis often develops in people who are over 50 years of age. However, it can develop at any age as a result of an injury or another joint-related condition.
Rheumatoid arthritis - Rheumatoid arthritis is a more severe, but less common, form of arthritis than osteoarthritis. It occurs when the body's immune system attacks and destroys the affected joints, causing pain and swelling to occur. This can lead to a reduction in movement and the breakdown of bone and cartilage.
Often starts in people between the ages of 40 and 50 years old but can affect people of any age. Women are three times more likely to be affected by the condition than men.
