After pregnancy, all kinds of changes have taken place on the pregnant mother. From the beginning, vomiting makes you feel at a loss. Then there are freckles, which make your face drop instantly, frequent toilet use, uterine contractions and so on. All of these make you feel inappropriate. Why are there so many changes in pregnancy? In fact, it is human chorionic gonadotropin, estrogen, progesterone, oxytocin and other hormones in pregnant mothers.
Human chorionic gonadotropin
Changes caused by pregnancy: early pregnancy
If you weren’t pregnant, you might never have known about human chorionic gonadotropin. It’s the messenger of pregnancy, it will tell you that your baby has taken root in your body. Morning sickness, nausea and vomiting is the most simple and crude way of expression.
According to the survey, 80% of pregnant mothers will wake up nausea in the early weeks of pregnancy and 60% will vomit due to the influence of human chorionic gonadotropin. However, pregnant Mommy should not worry too much. After the early stage of pregnancy, this symptom will gradually decrease or disappear.
During the 3 months of pregnancy, estrogen levels soar 30-50 times. This figure sounds a bit surprising, but in fact, it is beneficial to pregnant mummy’s body. It can promote the growth of the uterus, ensure adequate blood supply to the uterus, and play a positive role in the development of the fetus.
In addition, it also has a certain impact on the ligaments and pelvis of pregnant mothers, which will make ligaments relaxed and joint support ability decreased. Therefore, pregnant mothers are more likely to feel back pain and ankle swelling. By late pregnancy, it promotes the secretion of hormones related to skin pigments. As a result, some pregnant mothers have darker nipples and freckles on their faces. In view of this, the quality of pregnancy is closely related to the change of estrogen after pregnancy.
Change: relax muscles and increase urine output
During ovulation, the secretion of progesterone will continue to increase, which is to ensure that the endometrium is ready for new pregnant eggs. It can not only relax the muscles of the uterus to prevent the uterus from contracting too fast, but also relax the muscles of the whole body.
The bad side of progesterone is that it enlarges the kidney, so some pregnant mothers feel that urination increases at night and need frequent toilet use. In addition, it will also expand blood vessels and slow down the blood flow rate of pregnant mothers. Therefore, if pregnant mothers stand for a long time, they are prone to varicose veins, ankle swelling, and even blood pressure drop.
Change: relaxing the symphysis pubis
Pubic relaxation hormone maximizes in early pregnancy, stimulates the formation of new blood vessels in early pregnancy, and provides an appropriate environment for the growth of implanted eggs. With the advancement of pregnancy, the role of pubic relaxation hormone has also changed, and its main task has gradually become to relax the pubic symphysis. This bone is a door for babies to get in touch with the outside world. When the door is open, babies can pass through the pelvis more easily.
Pubic relaxation hormone can make a pregnant mother feel the pain of being kicked between her legs, but it can help delivery.
Changes caused: uterine contractions to ensure delivery
It is a hormone of the posterior pituitary gland, which accompanies the whole pregnancy. The contraction of the pregnant mother is caused by it, especially during childbirth. But why does it exist during pregnancy, while the pregnant mother has no severe contraction pain during childbirth? This is because the usual sedative effect of progesterone inhibits it. During childbirth, the cells in the uterus will be particularly sensitive to its role, at this time causing real uterine contraction, to ensure the smooth progress of childbirth.
The change: weaken your sexuality.
Prolactin is secreted by the pituitary gland and increases during pregnancy. However, due to estrogen, it does not affect breasts freely until estrogen decreases after childbirth. As long as new moms insist on breastfeeding, the secretion of prolactin will increase and the amount of milk will increase.
Studies have shown that prolactin can weaken the sexual desire of postpartum new mothers, but some people believe that lack of sleep and the endless demand of babies make new mothers’sexual desire decline.
The role of these hormones in pregnancy is necessary, all in order to nurture the baby, in order to let the baby grow up healthily, in order to let the baby smoothly come to the world. In this process, pregnant mothers have to suffer some discomfort or pain, but it is worthwhile, which is also a necessary experience for every mother.
