 This study found that reducing the intestinal microbiome through bowel cleansing and fasting for seven days can reduce symptoms of rheumatoid arthritis. The study also showed that this reduction was accompanied by changes in the microbiome composition with more fungal species being present in the gut. These findings suggest that alterations in the gut microbiome may play a role in the development of rheumatoid arthritis.
