Possible Link Between Obesity And Gum Disease

Impacting approximately one-third of the U.S. population, obesity is a significant health concern for Americans. It's a risk factor for developing type 2 diabetes, heart disease, and certain forms of cancer, and now, according to an article published in the January/February 2013 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD), it also may be a risk factor for gum disease.

"We know that being overweight can affect many aspects of a person's health," says Charlene Krejci, DDS, MSD, lead author of the article. "Now researchers suspect a link exists between obesity and gum disease. Obese individuals' bodies relentlessly produce cytokines, proteins with inflammatory properties. These cytokines may directly injure the gum tissues or reduce blood flow to the gum tissues, thus promoting the development of gum disease."

Gum Disease Found To Worsen Infection In Animal Model Of AIDS

Texas Biomed scientists in San Antonio have found that moderate gum disease in an animal model exposed to an AIDS- like virus had more viral variants causing infection and greater inflammation. Both of these features have potential negative implications in long term disease progression, including other kinds of infections, the researchers say in a new report.

The public health message from the study is that even mild inflammation in the mouth needs to be controlled because it can lead to more serious consequences, said Luis Giavedoni, Ph. D, a Texas Biomed virologist and first author of the study.

"This is important because moderate gum disease is present in more than 50 percent of the world population. It is known that severe gum disease leads to generalized inflammation and a number of other health complications, but the conditions that we created were moderate and they were mainly localized in the mouth," he added.
