The first uterine evacuation is also more damaging. If there is residue in the uterus, it can affect the contraction of the uterus, and if it leads to intrauterine infection, and if the endometrium is not repaired in time, it can lead to menstrual disorders and the possibility of infertility. If medication is not effective, surgery is required, and some instruments must be used to enter the uterine cavity to remove the residue, which will inevitably injure the endometrium. It is recommended to go to a regular public hospital with rich experience, excellent technology and regular operation, which can minimize the damage to the uterus. After surgery, pay attention to rest, make the vulva clean and dry, control the infection, strengthen nutrition, eat more high-protein food, eat more iron-supplemented food, will be conducive to the recovery of the endometrium.
