Obesity has been linked to osteoarthritis pain for decades. Doctors and scientists alike assumed it was the excess weight that put additional stress on the joints. However, the new research we’re seeing suggests otherwise: That the connection between obesity and osteoarthritis may have everything to do with your gut health—not the excess weight—instead.
Here’s how the scientific study unfolded…
Mice were fed a high-fat diet similar to that of a human fast food-based diet and became obese and diabetic in just a few weeks. In that process, their gut bacteria totally changed. Several inflammatory bacteria were found in the newly obese mice’s colons, and in turn, inflammatory symptoms showed up throughout their bodies (6).
These obese mice (with unhealthy gut bacteria) went on to have osteoarthritis symptoms that progressed much faster than the mice who maintained a healthier weight. Maybe that’s not so surprising, but the striking part is that when the obese mice were regularly fed a prebiotic (types of plant fibers that help promote healthy gut bacteria), their inflammation and joint symptoms went away—even when they remained overweight. Just by taking a prebiotic, their joint health was right on par with the thinner mice.
In this research, the common denominator for joint pain wasn’t about weight at all. Instead, it was inflammation caused by poor gut health. Could the same be true for humans?
More research is needed to uncover more links between osteoarthritis and gut health. But one thing we’re certain of is that it’s well worth the effort to maintain a healthy gut!
