How is gum disease associated with other health problems?

More studies are needed, but some researchers suspect that bacteria and inflammation linked to periodontitis (gum disease) play a role in some systemic diseases or conditions. Likewise, diseases such as diabetes, blood cell disorders, human immunodeficiency virus (HIV) infections and acquired immune deficiency syndrome (AIDS) can lower the body's resistance to infection, making periodontal diseases more severe.

Several studies link chronic inflammation from periodontitis with the development of cardiovascular problems. Some evidence suggests that oral bacteria may be linked to heart disease, arterial blockages and stroke.

People with diabetes often have gum disease. In addition, there is evidence that people with diabetes are more likely to develop and have more severe periodontitis than those without diabetes. Some studies suggest that periodontitis can make it more difficult for people with diabetes to control their blood sugar.
