Caution: Don’t fall into the trap of vaginitis

　　Prevention and control“ Vaginitis ”There is a trick
　　
　　because clinical The incidence of various types of vaginitis is increasing. Patients suffering from various types of vaginitis are eager to treat the disease and fall into various vicious circles. We can master the correct method of vaginal cleansing under the guidance of a doctor.
　　
　　female The reproductive tract has two natural lines of defense. One is the "anatomical line of defense", which has five checkpoints from the outside to the inside. The scope of a woman's vaginal cleansing often involves the first and second checkpoints. The first level is the vulva, where the labia majora on both sides naturally close together to cover the vaginal opening, making it difficult for bacteria to enter. The second checkpoint is the vagina. Due to the action of the pelvic floor muscles, the front and back walls of the vagina are close to each other and the vaginal opening is closed, which can prevent external contamination. If you are a multiparous woman, Postpartum vaginal relaxation , the defense function has been weakened. The other is the "physiological line of defense." On the one hand, under the influence of estrogen, vaginal epithelial cells continue to metabolize, proliferate and thicken, increasing their resistance to pathogens. On the other hand, under the action of vaginal bacteria, the glycogen rich in vaginal epithelial cells can be decomposed into lactic acid to maintain the normal acidic environment of the vagina and inhibit pathogens that are adapted to multiply in a weakly alkaline environment. This is medically called the self-purification effect of the vagina. So, healthy Although some bacteria exist in a woman's vagina, they usually do not cause inflammation.
　　
　　The pathogens that cause inflammation of the female reproductive tract come from two major sources, namely, from the bacterial flora that originally parasitized in the vagina, or from pathogens that invade from the outside. Under normal circumstances, vaginal bacteria dominate the vagina, with a small amount of anaerobic bacteria, mycoplasma and candida. These bacteria form a normal ecological balance. However, when the body's immunity is low, endocrine hormones change, or external factors such as tissue damage or sexual intercourse destroy the ecological balance of the vagina, these resident flora will become pathogenic bacteria, break through the vaginal barrier and cause infection.
