How poor oral hygiene may result in metabolic syndrome

Researchers have identified a novel mechanism by which periodontal disease may cause metabolic syndrome. By studying patients with metabolic syndrome, the researchers demonstrated high antibody titers against Porphyromonas gingivalis, the bacterium causing periodontal disease. In a mouse model, the researchers then showed that infection with this bacterium causes systemic insulin resistance and metabolic dysfunction in skeletal muscle by altering the gut microbiome. This study shows the effect periodontal disease can have on the entire body.
