Postpartum, menstruation is usually in postpartum 6-8 weeks to visit, and postpartum 8-12 weeks still future menstruation of new mothers only a few.
▎ why postpartum menstruation is delayed?
Postpartum amenorrhea is mainly seen in long-term lactation and postpartum hemorrhage, infection caused by Han’s syndrome; in addition, the body too high prolactin will inhibit ovulation and form amenorrhea.
Before delivery, although the concentration of prolactin in pregnant women is high, due to the influence of estrogen, prolactin cannot show its effect. After the delivery of the placenta, the effect of prolactin is strengthened by the sudden decrease of estrogen concentration in the body. In general, prolactin does not return to its pre pregnancy state until two weeks after birth. However, in lactating mothers, the level of prolactin is not only higher than that before pregnancy, but also increased due to the response of baby sucking. Lactation without menstruation of low estrogen can even maintain as long as 180 days. Therefore, as long as there is breast-feeding, the new mother’s menstruation should not come too early. Of course, there are also great differences among different people. In addition, part of the maternal breast-feeding time is too long, resulting in endometrial atrophic amenorrhea.
Another major amenorrhea occurs in women with massive postpartum hemorrhage accompanied by shock, severe postpartum infection, or disseminated intravascular coagulation. These symptoms can lead to amenorrhea, the so-called Han’s syndrome, which can also affect the secretion function of thyroid gland, such as emaciation, dyspepsia, chills, fatigue, atrophy of sexual organs, low basal metabolism, hair loss and other symptoms, which need to be treated by doctors.
