According to Diabetes.co.uk diabetes can make people more susceptible to halitosis. In people with diabetes, high blood sugar levels increase glucose levels in saliva providing food for bacteria in the mouth.
But according to a recent study, those turning to mouth rinses to combat bad breath such as those containing Chlorhexidine, may be unwittingly increasing their blood pressure by destroying ‘friendly’ oral bacteria that help produce nitric oxide.
“Results suggest that the utilization of an antibacterial mouth rinse negatively alters concentrations of salivary and plasma nitrate/nitrite with a concomitant rise in blood pressure.”
It seems that a return to more natural remedies such as chewing some fresh parsley would be a safer approach. It is said that its fresh scent and high chlorophyll content can have a deodorizing effect. Studies (not done on human breath, however) have shown that parsley can effectively combat foul sulfur compounds in the mouth.
