Malaise is a common clinical symptom after childbirth. It is the discharge of vaginal discharge after childbirth and is a normal physiological phenomenon. However, if it lasts for a long time or has an abnormal nature, it needs our attention. Generally speaking, the duration of postpartum dew is 4-6 weeks after delivery. If the postpartum dew lasts longer than 4-6 weeks, the possibility of incomplete dew may be considered. The primary cause of incomplete postpartum dew is incomplete uterine regeneration, which refers to the gradual return of the uterus to a non-pregnant state after delivery as the uterine muscle cells contract. However, in this process, if some factors cause incomplete contraction of the uterine muscle cells, it will lead to incomplete uterine regeneration, such as weak contraction of the uterine muscle layer, poor healing of the uterine incision during cesarean delivery, etc. When this occurs, the cause of incomplete uterine rejuvenation needs to be treated symptomatically. In addition, postpartum infections and placental membranes may also cause incomplete postpartum dew. To sum up, if you have incomplete postpartum dew, you should first consider the possibility of incomplete uterine regeneration, in addition to postpartum infection and placenta-fetal membrane residue.
