It is a normal physiological phenomenon to have a lot of leukorrhea after the IUD, but there is no change in the color of the leukorrhea, itching of the vulva, or local odor. There will be a small amount of bleeding after the IUD, and the IUD, especially the one with a tail wire, will stimulate the cervix to a certain extent, which will easily cause an increase in vaginal discharge, which will not last too long. If the leukorrhea increases for a long time after the IUD, and there is vulvar itching and brownish leukorrhea, it is considered to be caused by vaginitis or pelvic inflammatory disease, because not paying attention to the hygiene after the IUD or having sex too soon can easily cause bacterial or fungal infections, which can easily cause vaginitis and pelvic inflammatory disease. You can do routine examination of leukorrhea, ultrasound, etc. You can use metronidazole suppositories or ketoconazole suppositories under the guidance of the doctor, and it is also recommended to take gynecological Qianjin tablets for treatment.
