Smoking can change the ratio of bacteria in the oral cavity, undermining the health of the human respiratory and digestive system, as reported by the Internet publication for girls and women from 14 to 35 years Pannochka. net The good news is that after quitting cigarettes, the microflora of the oral cavity is gradually restored.
This is reported by the ISME Journal.
The authors of the new study, conducted in New York, studied a mixture of more than 600 species of bacteria that live in the mouth in an adult. These bacteria were taken from 1,200 Americans aged 50 years and older, including non-smokers, former and current smokers.
In the oral cavity of the smoker, more than 150 species of bacteria (many of which are pathogenic) begin to thrive, but at the same time the population of 70 other species.
In particular, the smoker's mouth lives on 10% more streptococci, which can cause oral infections and contribute to the loss of teeth.
In addition, Proteobacteria accounts for 12% of non-smokers, and for smokers - only 5% of the microbial population. Meanwhile, Proteobacteria helps to break down toxic substances and protect our body.
Is it possible to change the alignment of forces by quitting smoking? It turns out that you can, but not so fast. Ex-smokers who have given up a bad habit, the composition of the oral microflora is normalized, however, it takes about 10 years to completely restore it.
"Our study for the first time in the world confirmed that smoking has a powerful effect on the microflora of the oral cavity.
We need additional experiments, but already now we see that this habit weakens the protective barriers of the body and predisposes to the development of infectious and inflammatory and malignant diseases, "says study co-author epidemiologist Jiyoung Ahn from the Langone Medical Center.
More? cases of oral cancer are associated with smoking, and the cause may be a violation of microflora.
Recall that earlier scientists have already proved the role of imbalance of microflora in the development of immune diseases, such as Crohn's disease, as well as malignant tumors of the digestive tract.
