Mouthwash May Trigger Diabetes—If You Use Way, Way Too Much of It
Update | A new study claims very, very frequent mouthwash use is associated with a higher risk of developing type 2 diabetes. However, don’t clear it all out of your bathroom cabinet just yet. The association only existed for people who were using mouthwash at least twice a day, and the study only included people who had a number of pre-existing factors that put them at higher risk for developing the conditions.
The study, published on September 20 in Nitric Oxide, used data from 945 overweight or obese people who joined the San Juan Overweight Adults Longitudinal Study, based in Puerto Rico.
“Participants who used mouthwash at least twice daily had 55 percent significantly increased risk of developing pre-diabetes or diabetes over a 3-year follow-up compared to less frequent users, and 49 percent higher risk compared to non-users of mouthwash,” the authors wrote. Specifically, 30 percent of the group that used mouthwash at least twice a day developed one of the two conditions; that number was 10 percentage points less in the group of people who used mouthwash less frequently.
“There is no reason to believe it is restricted to overweight and obese people,” epidemiologist Kaumudi Joshipura told Newsweek, though being overweight is itself a risk factor for developing diabetes and prediabetes. ”We can’t know for sure, but at the same time, if I had to guess I think it may be generalizable to other populations.”
However, the study doesn’t show conclusively that mouthwash is causing diabetes. It only shows an association between significant usage and the diseas Continue reading
