ph7.50 in gynecological terms generally refers to a vaginal pH of 7.50. Under normal circumstances, the pH of the vagina should be between 3.8 and 4.4, so as to maintain the acidic environment of the vagina and the ecological balance within the vagina. There are many microorganisms in the normal vagina, but these microorganisms are in dynamic balance with the microenvironment of the female vagina and do not cause disease. The acidic environment of the vagina can inhibit the growth of other pathogens, and is conducive to the growth of Lactobacillus vaginalis. If the pH of the vagina is 7.50, i.e., the pH of the vagina is elevated, the acidic environment is altered, which is not conducive to the growth of Lactobacillus. If anaerobic bacteria overgrowth will lead to bacterial vaginosis; if long-term application of broad-spectrum antibiotics will also inhibit the growth of Lactobacillus, leading to the overgrowth of fungi and the emergence of vulvovaginal pseudomycosis. After menopause, the vaginal wall shrinks, the mucous membrane becomes thin, and the pH value in the vagina increases, the resistance of the patient decreases, and atrophic vaginitis is easy to occur. The pH of the vagina is 7.50 should be timely consultation, according to the specific situation to deal with. It is recommended to pay attention to personal hygiene and change underwear frequently.
