Osteoarthritis (OA) is a degenerative joint disease that typically affects the elderly population, although it can occur at any age. The exact cause of OA is not fully understood, but it is believed to be the result of a combination of factors, including:
- Aging: As we age, the cartilage in our joints naturally breaks down and becomes less elastic, making it more susceptible to damage.
- Joint injury: Previous injuries to a joint, such as a fracture or ligament tear, can increase the risk of developing OA in that joint.
- Overuse: Repetitive use of a joint over time can cause wear and tear on the cartilage, leading to OA.
- Obesity: Being overweight or obese puts extra stress on the joints, particularly in the hips, knees, and spine, which can lead to the development of OA.
- Genetics: There is some evidence that certain genes may be associated with an increased risk of developing OA.
- Other health conditions: Certain medical conditions, such as diabetes, gout, and rheumatoid arthritis, can increase the risk of developing OA.
It’s worth noting that while these factors can increase the likelihood of developing OA, not everyone who experiences them will develop the condition. Additionally, OA can occur in joints that have not experienced any of the above factors, indicating that there may be other factors at play as well.
