No menstrual cramps after giving birth

Introduction The recovery of menstruation in women after childbirth is a natural physiological phenomenon. Without menstruation, it is a warning of physiological abnormalities and cannot be easily ignored. Generally, if it is under normal circumstances, it is probably six weeks after birth to eight weeks of menstruation.

Cause

Postpartum amenorrhea is mainly seen in Hans syndrome caused by long-term breastfeeding and postpartum hemorrhage and infection. In addition, excessive prolactin in the body will also inhibit ovulation and form no menstruation. It is because women's own body is weak, maternal recovery is not good, and the amount of postpartum menstruation is small; some are because the kidneys have suffered certain damage during the production process, resulting in insufficient kidney gas, which leads to less menstrual flow after childbirth; some women In the process of production, there is more blood loss, and there will be less postpartum menstrual flow before the postpartum recovery is complete. Some women have less menstrual flow because of uterine dysplasia, and the endometrium stimulates ovarian hormones. The amount of postpartum menstruation is small.

Before delivery, the concentration of prolactin in pregnant women is high, but due to the influence of estrogen, prolactin can not play its role. After the placenta is delivered, the action of prolactin is enhanced by a sudden decrease in the concentration of estrogen in the body. In general, prolactin returns to pre-pregnancy status after two weeks of production. However, in lactating women, prolactin is not only maintained above pre-pregnancy, but also increased by the baby's reaction to sucking. Lactation-free menstrual low estrogen can even last for 180 days. Therefore, as long as there is breastfeeding, the new mother's menstruation should not come too early. Of course, the differences between different people are also great. In addition, some women have long-term breastfeeding, resulting in endometrial atrophy amenorrhea.

Another major amenorrhea condition occurs in women who have postpartum hemorrhage with shock, severe postpartum infection, or diffuse intravascular coagulation. These symptoms can lead to amenorrhea, the so-called Han's syndrome, which can also affect the secretory function of the thyroid, such as weight loss, indigestion, chills, fatigue, sexual atrophy, low basal metabolism and hair loss.

Differential diagnosis

The differential diagnosis of postpartum menstruation no longer occurs:

Lochia: Under normal circumstances, after delivery, the birth canal will discharge bloody secretions such as menstruation. This bleeding from the placenta implantation site is mixed with secretions such as decidua, tissue fragments and mucus remaining in the uterus. For the lochia. This is not a menstrual period.

Under normal circumstances, the first 4 to 5 days, the amount of lochia is red and red. One week after birth, the amount of lochia gradually decreased and turned brown; after the 10th day, the color became lighter and slowly turned from yellow to white with no special smell. Lochia usually disappears 4-6 weeks after delivery. But sometimes a small amount of brown lochia will last until the first menstrual cramps.
