As a girl, it is necessary to pay more attention to personal hygiene and various aspects of the body, including the pH value of the girl's vagina. The normal pH value of the girl's vagina has a specific range, and if it exceeds this range, that is, the pH value is abnormal, it is easy to suffer from gynecological diseases. Therefore, girls still need to have an understanding of the normal pH value.
What is the normal pH value for girls
Women of normal reproductive age have sufficient levels of estrogen in their bodies, which, together with lactobacilli that dominate the vagina, create an acidic environment (pH approximately 3.8-4.4)
Under normal circumstances, vaginal epithelial cells undergo periodic changes with the action of estrogen and progesterone during the menstrual cycle, especially surface cells, which are rich in glycogen. After glycogen secretion, it is broken down into lactic acid by vaginal bacteria parasitic in the vagina, maintaining an acidic environment with a pH of 4.5 in the vagina, thereby inhibiting the proliferation of pathogenic bacteria. Therefore, normal vaginal fluid has a self-cleaning or sterilizing effect. When there is inflammation or an increase in pH value in the reproductive tract, the vaginal environment changes and a large number of bacteria and white blood cells appear. The degree of cleanliness of vaginal fluid is classified based on the presence or absence of vaginal bacteria, as well as the amount of miscellaneous bacteria and white blood cells.
Why is the normal pH value for women acidic
The vagina of adult women is in a weakly acidic environment, with a pH value of about 3.8-4.5, which is beneficial for killing various pathogenic bacteria and opportunistic pathogens that enter the vagina. But when the local microenvironment of the vagina changes, the growth and reproduction of microbial communities can lead to vaginitis, commonly including trichomonas vaginitis, candidal vaginitis, and bacterial vaginitis. Trichomonas are not conducive to growth in a normal vaginal environment, and their growth and reproduction are most active in environments with a pH of 5.6-6.0. Therefore, even if trichomonas enter the vaginal environment below pH 5.0, it is difficult for them to grow and reproduce. Only when the vaginal pH value rises can trichomonas rapidly reproduce and grow, causing vaginitis.
The changes in the pH value of a girl's vagina are almost imperceptible to herself, and slight changes are not noticeable, which may lead to the pH value gradually deviating from the normal range. Therefore, it is best for girls to regularly go to the hospital for check ups to ensure that their physical condition is still good, and if there are any problems, they can seek early diagnosis and treatment.
