In order to recover as soon as possible after curettage, we should pay attention to proper rest after curettage, and it is best to stay in bed for the first three days. The most important thing is to wait a month after the operation to resume sexual life. Of course it's clean, but the endometrial trauma has not fully recovered. If it is carried out too early, the bacteria brought into the vagina can easily ascend, causing gynecological diseases such as endometritis, so it is best to ban sexual intercourse within one month. Curettage can usually be divided into diagnostic curettage and therapeutic curettage. The former refers to scraping the contents of endometrium or uterine cavity and sending them to pathological examination for a definite diagnosis. The latter is to scrape out all the contents of the endometrium or uterine cavity to achieve the purpose of hemostasis or other treatment. Even so, it does great harm to women. After curettage, a large area of wound will be left in the uterine cavity, at the same time, the vaginal wall and cervix have been opened, and the cervical mucus plug disappears, especially the secretion of cervix and uterine cavity is alkaline, which changes the acidic environment of vagina, makes pathogens easy to reproduce and may aggravate inflammatory infection. Of course, curettage is a common minor operation in gynecology, but it is potentially harmful to women's health. If the curettage is shallow, it may bleed because it is not clean, resulting in a second curettage. If the curettage is too deep, it will inevitably cause endometrial trauma and destroy the function of the uterus due to excessive curettage. One uterine cleaning, especially uterine cavity adhesion and cervical adhesion caused by repeated uterine cleaning, will cause infertility. If vaginal bleeding continues to be unclean after curettage, it should be checked and diagnosed, and sexual intercourse needs to be postponed. Reliable contraceptive measures must be taken after resuming sexual life, otherwise it is possible to get pregnant again. Repeated painless abortion will definitely do harm to the woman's health.
