How does obesity worsen joint pain and osteoarthritis?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Obesity is a major risk factor for joint pain and osteoarthritis. Excess body weight increases mechanical stress on weight-bearing joints—especially the knees, hips, and lower back—accelerating cartilage breakdown. Additionally, fat tissue releases inflammatory hormones (adipokines) that can worsen joint inflammation and pain, even in non-weight-bearing joints like the hands.

If you're experiencing joint pain, understanding the cause is the first step toward relief. Weight, inflammation, injury, and underlying conditions can all play a role—and pinpointing the source helps you take the right next steps, whether that's lifestyle changes, seeing a specialist, or seeking urgent care. Take a free, instant, online symptom check to get personalized insights in minutes.

Explanation

Obesity can make joint pain and osteoarthritis worse in a few ways. First, carrying extra weight puts more stress on the joints, especially the knees. This extra pressure can wear down the cartilage, which is the cushion in the joints, leading to pain and stiffness.

Additionally, obesity can cause hormonal changes in the body. These changes can increase inflammation, which is when your body reacts to injury or harm. Inflammation can make joint pain worse and speed up the damage to the joints.

In summary, obesity affects joint health by both mechanical stress and hormonal changes. Managing weight can help reduce the strain on your joints and may help with reducing pain and slowing down the progression of osteoarthritis.
