Several factors can lead to an increased risk of OA, including:
Age. The risk of developing osteoarthritis increases with age. In general, symptoms appear in people over 50, but they can also appear in young people who have experienced joint injuries.
Gender. Women are more likely to develop OA than men.
Obesity. Excess weight adds stress to weight-bearing joints. At the same time, fat tissue produces proteins that cause joint inflammation.
Overuse. Repeated joint movements at work or during sports can wear down joint cartilage.
Joint injury. Injuries can strain your joints, increasing the risk of OA. For example, a bone fracture or ligament tear can cause OA. Even older injuries that have seemingly healed lead to an increased risk.
Genetics. Those who have family members with OA are more likely to develop the condition.
