What impact does weight reduction have on OA?

A recent randomized trial concluded that an intensive weight loss intervention program of diet and exercise improved physical function in older obese adults with knee osteoarthritis (OA) (Miller et al, 2006).

Obesity is considered a risk factor for osteoarthritis, particularly OA of the knee, but also OA of the hip. Patients who suffer from both obesity and OA of the hip or knee, should talk to their health care provider about diet and exercise options as these types of interventions may improve their OA symptoms. Always talk to your physician before starting on an exercise program or making any dietary modifications.
