Obesity and Gum Disease
Some new research has determined that obesity increases susceptibility to gum disease. The NewScientist is on it:
Salomon Amar at Boston University Medical Center in Massachusetts and his colleagues infected both lean and obese mice with Porphyromonas gingivalis, a bacterium that causes gum disease, and then studied how their bodies coped. Some of the mice were infected directly in the gum area; others had the bacterium injected into their bloodstream. In both cases, fat mice were slower to kill the bacterium because their immune response was blunted: immune cells called macrophages produced fewer cytokines - chemicals that would usually draw in other immune cells to fight off infection. Within 10 days of infection, obese mice infected at the gum also showed 40 per cent more bone loss in their tooth sockets.For more obesity news, be sure to check out DiseaseProof’s obesity category.
