Obesity and Joint Health
Obesity is a major risk factor for joint damage, particularly in weight-bearing joints like the knees, hips, and spine. Carrying excess body weight increases mechanical stress on joints, accelerating cartilage wear and leading to pain, stiffness, and reduced mobility[1][2][3]. Even a modest weight gain—just 10 pounds—can increase the force on the knee by 30–60 pounds with each step[2]. Obesity also contributes to systemic inflammation and hormonal changes that further damage joint tissues[1][4]. Weight loss, even as little as 5–10%, has been shown to significantly reduce joint pain and slow the progression of osteoarthritis[5].
Physical Activity
Regular physical activity is essential for maintaining joint health and managing joint conditions. Exercise helps by:
- Lubricating joints and promoting the circulation of nutrients to cartilage[6].
- Strengthening the muscles, ligaments, and tendons that support joints, reducing the load on weakened or damaged areas[6].
- Reducing inflammation and supporting healthy weight management[6].
- Improving flexibility and range of motion, which helps prevent stiffness and pain[6].
