It is possible for the residue of spontaneous abortion to heal by itself, but it is also possible that it will not heal by itself. 1. It may heal by itself: if the residue is small, some patients rely on the contraction function of the uterus and their own absorption ability, it is possible to expel or absorb the residue of spontaneous abortion, so as to realize self-healing. 2. May not be self-healing: in the ultrasound examination, the volume of the residue of spontaneous abortion is relatively large or there is a blood flow signal, the residue is very likely to not be self-healing, you need to take the new biochemical particles under the guidance of the doctor or motherwort granules for treatment and regular ultrasound, if the effect of the medication is not obvious, then we need to consider the removal of the uterus. After the occurrence of spontaneous abortion, it is recommended to seek timely medical treatment to avoid delayed and life-threatening conditions.
