Dr. Grant Cooper: Obesity does not directly cause osteoarthritis, but it increases the amount of stress that the weight-bearing joints must carry and contributes to joint wear and tear.
Here are five facts about how obesity and arthritis are linked.
If you are obese, your knees and hips experience up to 3 times as much pressure with each step.
2. Climbing Stairs
If you are obese, your knees and hips experience up to 6 times as much pressure when walking down a flight of stairs.
3. Weight Gain Increases Risk
For every ten pounds of excess weight gained, the risk of developing osteoarthritis increases by approximately 40%.
4. More than just the hips or knees
Obesity is a risk factor for developing arthritis in the knees, hips, hands and ankles.
5. Weight loss among women
Overweight women who lose as little as 11 pounds decrease their risk of developing arthritis by more than 50%.
