In the postpartum period, if the uterine fluid accumulates, it is clinically caused by poor uterine regeneration in the vast majority of cases. It is suggested that in this case, you can take Yimoucao capsule or Wujia biochemical capsule orally for treatment, and use the medicine for 7-10 days continuously, and then give a review. In addition, if uterine effusion occurs after delivery, it is also related to the usual diet, such as eating too much ginseng, deer antler, red dates and aconite, which may also cause poor uterine regeneration after delivery, so the uterine cavity will have effusion. The main treatment for this situation is to stop using the above mentioned drugs or foods, and this bleeding state will be improved.
