Check out some of the other more unexpected effects of diabetes and how you can protect yourself.
People with diabetes are more likely to develop periodontal disease, an infection of the gum and bone that can lead to painful chewing problems and tooth loss. “This is due in part to elevated blood sugar that modifies the collagen in all of our tissues,” Rodbard says. “It’s also due to a slight increase in susceptibility to infections of all kinds.” The two conditions have been so strongly linked that simply having gum disease may be a sign of future type 2 diabetes.
In a Columbia University Mailman School of Public Health study of 9,000 people, those with higher levels of periodontal disease were nearly twice as likely to become diabetic within the next two decades than people without gum disease, even after adjusting for age, smoking, obesity, and diet. Unfortunately, it’s a negative feedback loop: Not only does diabetes make gum disease worse, but gum disease—specifically inflammation of the gums or development of deep abscesses—can raise blood sugar and make diabetes harder to control, according to Hamdy. To prevent periodontitis, brush and floss daily and consider using a mild antiseptic mouthwash such as Listerine to knock out any lingering plaque.
