There is usually leukorrhea after hysterectomy. The leukorrhea mainly comes from the uterus, the vagina and the external vaginal opening because the vaginal mucosa produces mucus, so as long as the vagina is not removed, the leukorrhea will be present. Most hysterectomies do not require the removal of the ovaries at the same time, so there is no significant effect on the leucorrhea. After surgery, estrogen and progesterone are secreted as usual, and the vaginal mucosa secretes mucus and produces leucorrhea as usual. Sometimes the hysterectomy is accompanied by removal of bilateral adnexa, that is, removal of ovaries and fallopian tubes. The obvious decrease of estrogen and progesterone after surgery will lead to a decrease of vaginal mucous membrane secretion and obvious leucorrhea, decrease of mucous membrane secretion and thinning of mucous membrane, which will lead to difficulty in sexual life or painful intercourse. If there is quite a lot of leucorrhea after hysterectomy, instead of an increase, especially if there is a change in the color of leucorrhea, yellowish green or green, or even accompanied by obvious vaginal itching, it is a sign of postoperative infection. Because antibiotic anti-infection treatment is routinely given after hysterectomy, it will lead to vaginal dysbiosis, and dysbiosis can cause vaginitis, so let the doctor check the vaginal discharge to determine whether it is vaginitis, and then give appropriate treatment according to the specific type of vaginitis, such as topical antifungal drugs such as clotrimazole tablets for mycosis fungoides, plus oral antifungal drugs if necessary.
