Effect of Gargling away the ‘bad’ bacteria in type 2 diabetes

Rinse mouth everyday

Scientists have discovered that using a mouthwash for gargling can decrease the presence of harmful bacteria in the mouths of individuals with type 2 diabetes. Interestingly this decrease in bacteria was connected to management of blood sugar levels in certain patients. Considering that issues resulting from these bacteria are associated with various severe inflammatory conditions, like heart disease and Alzheimers this uncomplicated remedy could potentially have broad reaching implications.

Beyond having bad breath there is a mounting body of evidence suggesting that persistent inflammation in the mouth such as that seen in gum disease is linked to serious conditions like Alzheimers disease and type 2 diabetes. Recently a team of researchers from Osaka University has discovered a method to combat bacteria that could contribute to such health issues.

As detailed in a publication in Scientific Reports the researchers found that individuals with type 2 diabetes who used an antiseptic mouthwash experienced a reduction, in the levels of bacteria associated with periodontitis.

Excitingly some patients who had levels of certain bacteria also showed significant improvements in managing their blood sugar suggesting promising potential for future clinical use.

According to Saaya Matayoshi the lead author of the research there are three harmful bacterial types associated with periodontitis and oral health issues. These include Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia.

The team set out to investigate if using a mouthwash containing the chlorhexidine gluconate could reduce the presence of these three bacterial species in individuals with type 2 diabetes.

Over the course of a year researchers collected saliva and blood samples from 173 patients on an bimonthly basis. Saliva samples were examined for the presence of the three species while blood samples were analyzed to measure HbA1c levels as an indicator of blood sugar control.

During the half of the study duration participants rinsed their mouths with water while during the latter half they used the antiseptic mouthwash. This allowed researchers to compare the effectiveness of mouth rinsing alone versus using mouthwash.

Kazuhiko Nakano, author of the study notes that gargling with water did not show any impact, on bacterial species or HbA1c levels during the initial 6 months.”After making the switch, to mouthwash and gargling daily the number of bacterial species decreased in general among the patients.”

The researchers also discovered that even though there were no shifts in HbA1c levels when patients rinsed with the antiseptic mouthwash there seemed to be significant variations in how individuals responded.

For instance when they divided the participants into older groups they found that younger patients experienced greater reductions in bacterial species and notably better blood sugar management with the mouthwash compared to water.

Considering the connection between oral health and serious illnesses finding simple ways to enhance oral hygiene carries significant implications. If researchers can pinpoint patients who’re likely to benefit from antiseptic mouthwash this convenient treatment could potentially enhance the quality of life for individuals dealing with conditions, like diabetes, dementia, cardiovascular disease and respiratory infections linked to periodontitis.
