How can women protect the ecological balance of their vagina?

　　According to research, there are 100-500 types of various microorganisms in the intestines. In ecological balance, they are not only harmless, but beneficial ； But when the ecological balance is out of balance, it is harmful.

　　The vagina is certainly no exception. The upper end of the vaginal meridian and Uterus , the fallopian tube is connected directly to the abdominal cavity, and the lower end is directly connected to the outside world； Its opening is in front of the urethra and behind it is the anus, making it susceptible to contamination. Among them, there are various resident microorganisms (including bacteria, viruses, mycoplasmas, etc.), and many pathogens can be temporarily introduced due to sexual contact.

　　In the past, someone conducted a study on 280 pregnant women, and a total of 19 species (genus) of microorganisms were detected from the vagina, such as Corynebacterium, Lactobacillus, Epidermal Grape Resident bacteria such as cocci, and even Escherichia coli or Staphylococcus aureus, which are considered to be highly pathogenic (due to the advancement of testing technology, more are found today). However, why do some women who are not very particular about personal hygiene not develop the disease, while those who are very particular about personal hygiene sometimes develop severe vulvar, vaginal or pelvic inflammatory disease disease, and it still cannot be cured for a long time? This is related to ecological balance or not.

　　It turns out that women's reproductive organs have their own unique defensive structures and functions both in terms of detachment and physiology. The labia minora on both sides of a woman's vulva often close together, and the front and back walls of the vagina are close together, forming a natural defense barrier. More importantly, the vaginal epithelial cells, under the influence of estrogen, can undergo periodic changes and fall off. Because they contain different levels of glycogen, under the action of vaginal bacteria, the glycogen is converted into lactic acid to maintain the vaginal pH between PH4-4.5. In this way, microorganisms that are adapted to survive in an alkaline environment cannot grow and reproduce here. This naturally occurring defense function is also called "self-purification."

　　When the ecology is balanced, the bacterial flora in the vagina has a certain combination structure. For example: how many species (genus) of microorganisms there are, their proportions, which part of the vagina they live in, etc. are all strictly controlled by ecological factors. Through this control, not only the resident normal flora will not escape, but it will also make it difficult for foreign microorganisms to settle down.

　　when women suffer from anemia , malnutrition, high fever, excessive weakness or fatigue, due to reduced resistance, the normal physiological combination between microorganisms will change, resulting in an imbalance of bacterial proportions and pathogenicity. Usually, in some healthy Among carriers, although real pathogenic bacteria, such as typhoid bacilli or dysentery bacilli, can be detected, they are not common. However, if the ecological balance is imbalanced, it will lead to bacterial flora imbalance.
