Arthritis is a common disease that primarily affects the joints, causing pain, swelling, and restricted movement. It is not a single disease but rather a general term encompassing a variety of conditions, including osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. The occurrence of arthritis is associated with multiple factors:
1. Age: As people grow older, joint cartilage gradually wears down, significantly increasing the likelihood of developing osteoarthritis.
2. Genetic factors: Arthritis tends to cluster in families, clearly indicating that genetics play a role in its development.
3. Obesity: Excess body weight places additional stress on joints such as the knees and hips, accelerating cartilage wear and increasing the risk of arthritis.
4. Injury and overuse: Repeated joint injuries or prolonged overuse—common among athletes and manual laborers—can increase the likelihood of developing arthritis.
5. Immune system dysfunction: For example, in rheumatoid arthritis, the immune system mistakenly attacks the body's own joint tissues, causing inflammation.
