Hot summer, the third floor of the hospital gynecology outpatient clinic crowded with patients who came to the clinic, I just sat down, the nurse led a young patient, the patient Zhang sat down after an anxious account of their own troubles: she is a teacher, married and childless, regular menstruation, but the last 1 month vulvar itching, buy their own gynecological cleansing, skin cleaner wash the more serious, but also emphasize that they pay attention to cleanliness and hygiene, underwear are She also emphasized that she pays close attention to cleanliness and hygiene, washing her underwear by hand, taking a bath before intercourse, and not touching anything unclean, etc. She looked puzzled. Look at a puzzled her, through careful questioning of the history and examination, I found that the cause of Zhang’s disease is “too clean”, incorrect vaginal douching, vaginal flora imbalance, gave her a lactobacillus vaginal capsule, put a week after the follow-up, vulvar itching disappeared, I specifically explained to her, don’t often use the douche solution to douche the vagina, bathing, also don’t use the shower to the vulva. Do not use the shower to rinse the vulva and vagina. Do you remember the advertisement of Gynecol? In fact, women’s vagina is not like what the advertisement says: “Washing is healthier”, that is a seriously misleading advertisement for women. Then why can’t you wash indiscriminately? Because douching leads to an imbalance in the normal vaginal environment. The common cause of vaginitis and other gynecological inflammation: vaginal environment imbalance. The normal vagina is a tube made up of muscle and mucous membranes, and the tube is host to the vaginal bacillus. The vaginal wall has many transverse folds. The surface of the vaginal mucosa is composed of complex squamous epithelium, the surface cells of the squamous epithelium are affected by estrogen and secrete glycogen, which is broken down into lactic acid by the action of vaginal bacilli to maintain a certain degree of acidity of the vagina, with a normal pH value of 4-5, so the vagina is in an acidic environment, which can inhibit the reproduction of disease-causing bacteria, maintain normal cleanliness of the vagina, and prevent vaginitis from occurring. The vagina is an acidic environment, so the vagina is acidic. It can also be put this way: normal vaginal fluid has a self-purifying or sterilizing effect. If frequent douching, put this system balance is broken when, will appear due to vaginal flora imbalance caused by a variety of vaginitis. Once you have vaginitis, the vagina is already infected with germs, and excessive vaginal douching will flush germs near the vaginal opening into the cervical canal or uterine cavity, leading to endometritis and pelvic inflammatory disease, and even infertility. Douching during menstruation or ovulation can also lead to ectopic pregnancy, and recent studies have shown that excessive vaginal douching also increases the incidence of cervical cancer and AIDS. In addition to these vaginal douche solution can not be used indiscriminately, normal bathing can not use soap to wash the vulva for a long time, which will cause the acidic environment is destroyed, so that the bacterial flora imbalance, the local resistance to decline, triggering gynecological diseases, can be warm water to flush the vulva, but remember to wash the vulva with running water, rather than the vagina. Finally, remind the majority of female friends, in order to avoid the occurrence of vaginitis and other gynecological diseases, women should actively cultivate good habits and routines of life, the biological clock is not disordered; appropriate physical exercise, enhance physical fitness and body immunity, do not give the opportunity to stay harmful germs. Diet, try not to eat too much cold and sour food. In addition, before each sex, it is best for both husband and wife to use flowing warm water to clean the external genitals before coitus. In addition to fixed sexual partners, when a party has external genital inflammation, do not cohabit temporarily, to avoid cross-infection. If there is an uncomfortable performance, timely to the regular hospital.
