Menstruation refers to menstruation. Menstruation after IUD removal may or may not be normal, depending on the specific situation. 1. Normal: Women’s menstruation is related to the function of hypothalamus-pituitary-ovarian axis, and the normal removal of IUD will not affect this function. In addition, women’s menstruation is also affected by the hormone level in the body, and the removal of IUD will not affect the hormone level in the body, so the removal of IUD will not lead to menstruation disorders in normal circumstances. 2. Abnormal: If the IUD is not operated properly and triggers infection of the uterine lining, endometritis will occur, which will affect the menstruation, increase the amount of menstruation, and prolong the menstruation period, etc. In addition, if the IUD is not operated properly, it will not affect the menstruation. In addition, if the removal of the IUD causes serious damage to the lining of the uterus, and the lining of the uterus cannot return to normal in time, it may also affect menstruation, resulting in symptoms such as low menstrual flow. After removing the IUD, you should observe whether the menstruation is normal or not, if there is any abnormality, it is recommended to actively go to the hospital and follow the doctor’s instructions to deal with the treatment, and it is recommended to choose regular hospitals and standardize the operation of removing the IUD.
