COPD improved by tweaks to microbiome via fecal transplant or diet
By Paul McClure COPD symptoms were alleviated by a healthier gut microbiome Depositphotos Improving the health of the gut microbiome by way of fecal transplant (in mice) and dietary modification (in humans), has been shown by researchers to noticeably improve COPD symptoms. The finding could lead to microbiome-targeted treatments that provide relief to people suffering from...
