The gut microbiome plays an important role in digestion and keeping the immune system healthy. Through the survey, experts found that there was a difference between the intestinal microbiota of babies born vaginally through the mother's vagina compared with those born by caesarean section.
The composition of gut bacteria in infants born by caesarean section is different from that of infants born vaginally. Newborns are often exposed to their mother's bacteria at birth, so they have a richer gut microbiome. At birth, the baby's body is completely sterile, but during natural vaginal birth, the baby receives bacteria from the mother's vagina and intestinal microflora, mainly Bacteroides, Lactobacillus, and Bifidobacterium. These bacteria affects the gut microbiome and stimulates white blood cells, other components of the immune system. From these initial bacteria, the intestinal microbiota in children begins to establish.
According to the European Medical Organization, 50-55% of babies will have problems with the digestive system, and this rate is much higher in babies born by cesarean section. Children born normally inherit from their mothers beneficial bacteria, thereby forming beneficial bacteria in the intestinal tract to help children digest better, reduce the risk of food allergies, and reduce the incidence of diseases. enteric infections by creating a physiological environment against pathogenic bacteria. On the other hand, intestinal bacteria also participate in the synthesis of vitamins K and B, which are very good for the health of children.
If the baby is born by cesarean section, there will be no chance to come into contact with the bacteria in the mother's microbiome, thus leading to an imbalance in the baby's gut microbiota from birth.
Humans cannot live and survive without a microbiome, especially beneficial bacteria. They not only help digest food, but when entering the body, beneficial bacteria also proliferate, attach to the intestinal mucosa, compete, and inhibit the growth of harmful bacteria, including bacteria. intestinal bacteria.
The president of immunology, Mario Clerici, asserts: The body is made up of 10 trillion cells. Besides, the amount of bacteria that exists in each person is 10 times higher than that number of cells, including beneficial and harmful bacteria. Most of them are concentrated in the digestive system. According to him, each person has about 2kg of bacteria living in the intestinal tract. Of which, beneficial bacteria account for about 85% and harmful bacteria account for about 15%. When this ratio is out of balance, harmful bacteria will increase, causing a decrease in immunity. As a result, the resistance is gradually reduced, causing inflammatory diseases, including digestive disorders.
Gut bacteria perform many tasks including connecting with the immune system, protecting the body from pathogens, and assisting in accessing nutrients from food. Some components of the gut microbiota are genetically dependent. The bacterium Christensenellaceae is one of the most genetically dependent species. This species can cause bacterial dysbiosis that makes the microbiome unhealthy.
