Why do you need to lose weight when you have knee osteoarthritis (OA)?

ANSWER

When you carry extra pounds you also speed up the loss of cartilage in your knees. That's the stuff that creates a cushion between your bones. If you don't have enough, your bones start to rub against each other. And that leads to irritation, pain, and swelling.

When you drop a few pounds, you won't reverse your OA or create new cartilage. But it can ease your symptoms, improve how well you get around, and prevent more damage to your joints.
