It is important to keep the stool properly soft in order to produce stool without placing a burden on the anus. One way to do this is to improve the intestinal environment.
There are as many as 1,000 varieties of or 100 trillion bacteria in the human intestine, including good bacteria (Lactobacillus and Bifidobacterium, etc.), bad bacteria (Clostridium perfringens and Staphylococcus, etc.), and opportunistic bacteria (Bacteroides, nontoxic strain of Escherichia coli, etc.).1) These bacteria are known as intestinal flora because they look like flower fields where plants are growing in groups of different types (flora in English). The balance of the intestinal flora is important to maintain a healthy intestinal state.
In healthy intestines, good bacteria help prevent the colonization and growth of bad bacteria and excrete harmful substances produced by bad bacteria from the body. Opportunistic bacteria support the dominant bacteria.
Therefore, if this balance is lost for any reason and the number of bad bacteria in the intestine increases, the intestinal environment deteriorates, causing constipation or diarrhea. In other words, maintaining an environment that has more good bacteria than bad bacteria will lead to the production of good stool with no burden on the anus.2), 3)
Recent studies have shown that improvement of intestinal environments other than bowel movement is effective for the prevention and recovery of various diseases, such as cancer, hypertension, and diabetes.4) Why do you not pay attention to actions to balance the intestinal flora in your daily life?
