what causes osteoarthritis

Osteoarthritis is mainly caused by the wear and tear of the cartilage in your joints, and yes, aging is a significant factor as cartilage tends to wear down naturally over time. However, it’s not just aging—there are multiple factors that can contribute to the development of this condition. Genetics can play a role, which you’ve noted with your mom’s issues. Obesity is another risk factor, as the extra weight adds stress to weight-bearing joints, like your knees, which can accelerate cartilage breakdown. That college knee injury you mentioned might also be a contributor; previous injuries can pave the way for osteoarthritis to develop earlier or more severely because they can damage the joint cartilage or change the way you use that joint, leading to additional stress over time.

Lifestyle factors indeed have a role in the progression of osteoarthritis. High-impact activities can exacerbate the condition by putting excess stress on your joints. Consider moderating activities that put repetitive stress on the knees, such as running on hard surfaces. Instead, low-impact exercises like swimming or cycling might be better alternatives. If weight is a concern, working on weight loss can significantly reduce joint stress and help alleviate symptoms. As for your diet, focus on a balanced one rich in antioxidants and omega-3 fatty acids which can help reduce inflammation. Supplements like glucosamine or chondroitin are sometimes recommended, but it’s best to discuss these with your healthcare provider before starting any new regimen. Managing osteoarthritis involves a combination of lifestyle modifications, physical therapy, and sometimes medications to manage pain and inflammation, so if your symptoms persist or worsen, it’s important to get an evaluation from a physician to tailor a management plan that suits your needs.
