In this segment Christopher Ellis explains recent research—about eight studies—showing a strong link between gut pathology and the wear of cartilage in arthritic joints, particularly after knee replacement. The studies report that pathogenic gut bacteria are found both in the gastrointestinal tract and within the affected joint, where they appear to inhibit progenitor cells responsible for generating new cartilage. This inhibition reduces cartilage turnover, contributing to joint degradation. Ellis advises anyone suspecting gut issues to consult a healthcare professional, as gut health may be a contributing factor, and points viewers to his website for the referenced studies and future updates.

There is a high correlation between the gut and joint replacement, joint wear-down. There's about 8 studies that came out recently. You can always find them on my website if you like. They've linked the gut pathology to wear-down of cartilage. So, what they're finding is there are progenitor cells that turn over new cartilage. So, you're supposed to have new turnover. And, in a joint that's arthritic, They are finding the same pathogenic gut bacteria present not only in the gut but in that joint as well that appear to be inhibiting those progenitor cells. So, you're not getting that new turnover. So, if you think you have a gut issue, definitely get with somebody and check that out because that may be a contributor. So, there's more on that to come.
