Osteoarthritis: why you have to control your weight
If extra pounds (ie, a BMI greater than 25) encourage osteoarthritis, it is not just because they "ballast" the joints. Excess body fat, especially that of the abdominal perimeter, triggers the production of small inflammatory proteins called adipokines that are released into the blood. "But they accelerate the destruction of cartilage," says Dr. Laurent Grange, rheumatologist.This is precisely why we find in the obese twice as many osteoarthritis of the fingers than in the general population, in a zone where the mechanical stresses are however much less important than in the lower limbs.
"If you lose 10% of your weight, you will improve your quality of life by 25%, both in terms of pain and mobility," says our specialist. But beware, when the needle of the scale is moving to the wrong side, rather than adopting a drastic diet, it is better to consider a rebalancing food with a nutritionist doctor. "No diet is recommended after 70 years, especially since it is an age where some people tend to lose appetite", warns Jerome Auger.
