Uterine waste is usually removed by normal menstruation or sometimes by surgical curettage. Uterine waste is mainly the aging of the endometrium prior to menstruation, and this aging endometrium is sometimes referred to as uterine waste. If present for a long time, it may increase the likelihood of endometrial lesions occurring. The female organism has a regular method of removing uterine waste, namely menstruation. Usually women have a period once a month. The first half of the menstrual cycle is the follicular phase, in which the endometrium gradually thickens; the second half of the menstrual cycle is the luteal phase, in which the endometrium further thickens, the corpus luteum gradually shrinks, the estrogen and progesterone levels drop, and the endometrium peels off, manifesting as menstruation. The menstrual blood is mainly composed of endometrium, and these endometrium need to be removed regularly to avoid endometrial hyperplasia. Women are advised to maintain good living habits, reasonable diet, regular work and rest, and proper exercise. Pay attention to personal hygiene, change underwear regularly, and do not touch cold water during menstruation. Uterine garbage also includes real garbage such as incomplete abortion, failed medical abortion or residues after abortion. These real uterine wastes need to be removed in time and if not removed in time, they often cause secondary infection and spread to the fallopian tubes causing destruction of the fallopian tube mucosa resulting in secondary infertility. Therefore, it is important to review the ultrasound after an incomplete abortion or a medical or human abortion. If the ultrasound indicates residual uterine cavity, you can take blood-boosting drugs for treatment and, if necessary, surgical removal of the uterus to remove this garbage. It is still important to review the ultrasound after the removal of the uterus to prevent further residues. Sometimes uterine waste can be combined with uterine infection, and antibiotic anti-infection treatment should be given along with surgical removal.
