It is a normal physiological phenomenon for women of childbearing age to have more leukorrhea, usually milky white, after pregnancy due to changes in hormone levels in the body. As pregnancy progresses, adaptive changes occur in various organ systems of pregnant women to facilitate the needs of fetal growth and development and delivery. At the same time, the placenta produces a large amount of estrogen and progesterone, causing significant changes in the cervix, vagina and vulva. After pregnancy, the cervix is hormonally enlarged and hypertrophied by the glands in the cervical canal, making the cervix gradually softer and purplish-blue in color. After pregnancy, the cervical mucus increases and forms sticky mucus plugs, which are rich in immunoglobulins and cytokines and have the function of protecting the uterine cavity from foreign germs. At the same time, after pregnancy, vaginal exfoliated cells and secretions increase in the form of white paste, i.e. leucorrhea. Vaginal epithelial cells contain increased glycogen and increased lactic acid content, which reduces vaginal pH and is not conducive to the growth of pathogenic bacteria and helps prevent infection. If the leucorrhea increases after pregnancy and is milky white, no special treatment is needed, just pay attention to hygiene and cleanliness; if the leucorrhea is yellow or appears to be tofu-like or foamy in appearance, accompanied by odor, it is an abnormal condition and you should be alert to the possibility of combined vaginal inflammation, such as mycosis fungoides, trichomonas vaginitis, bacterial vaginitis, etc. You should consult a hospital for appropriate examination and treatment.
