10. Gum Disease

People with high blood sugar levels are more likely to develop infections of the gums and the underlying bone that can lead to chewing problems and tooth loss. This is because the high levels of sugar affect the ability of tissues to repair themselves, and also destroys the connective tissue called collagen, making them more prone to infection. It was also found that the infection and inflammation caused by diabetes on gums caused a vicious cycle, raising blood sugar levels, making the diabetes more difficult to control. To make it worse, people with gum disease have two to three times the risk of having a heart attack or stroke.
