The dangers of low placenta during pregnancy

Pregnancy is such a happy thing, but there are many issues to pay attention to during pregnancy. For example, if the placenta is low, it can easily cause miscarriage. I heard from a cousin that when she was about to give birth, she found that the placenta was in a low position. This scared her family and the delivery was extremely difficult. So, what are the dangers of a low placenta during pregnancy? Let me introduce it to you below, hoping it will be helpful to all pregnant mothers.

Generally, placenta previa can easily lead to premature birth. If you have abdominal pain and vaginal bleeding, you should go to the hospital and try to avoid strenuous activities. Some pregnant mothers may experience low-lying placenta during pregnancy. A normal fertilized embryo will be inside the uterus, but if the fertilized embryo is implanted very low, when the placenta grows, the larger and larger placenta will be located in a relatively lower position in the pregnant mother's uterus, close to the cervical opening but not covering it. This is a low-lying placenta, also known as marginal placenta previa.

Low-lying placenta is a type of placenta previa. In fact, the low-lying placenta mentioned above is just a type of placenta previa. Placenta previa is divided into three types: complete placenta previa, partial placenta previa and low-lying placenta. Complete placenta previa means that the placental tissue completely covers the internal cervical opening; partial placenta previa means that only part of the placental tissue covers the cervical opening. Possible consequences of a low-lying placenta: As the pregnancy progresses, especially in the late pregnancy or after delivery, the lower segment of the uterus gradually stretches, the cervical canal disappears, and the cervical opening dilates, but the placenta does not develop with the expansion of the cervical opening. As a result, it detaches from its attachment point, and blood vessels rupture, causing vaginal bleeding. When the amount of bleeding is heavy, the pregnant mother will develop anemia; when the bleeding is severe, she may go into shock and faint, and the baby in her belly may suffer from lack of oxygen, respiratory distress, or even death. Although this bleeding depends on the type of placenta previa, the chance of heavy, recurrent early bleeding is relatively low in low-lying placentas. However, during labor, each uterine contraction will pull the lower segment of the uterus upward, often causing increased bleeding and resulting in serious consequences. At the same time, because the placental detachment surface of placenta previa is close to the external cervical os, bacteria can invade the placental detachment surface from the vagina. Coupled with postpartum anemia and weak physical condition, it is easy to get puerperal infection. Moreover, premature and perinatal mortality rates will also increase.

How to safely get through the situation of low-lying placenta? Don’t be too anxious, because anxiety will only affect the development of pregnancy. Self-care: When a pregnant mother has a low-lying placenta, she should take appropriate self-care measures, but avoid all strenuous exercise, such as running, jumping, etc., and some actions are absolutely inappropriate. For example, squatting. Pregnant mothers already have a bulging abdomen, which puts a lot of pressure on their lower limbs, so it is not easy for them to squat. If a pregnant mother with a low-lying placenta squats, the cervix will expand and the placenta located lower will be stretched, causing detachment and bleeding. Therefore, pregnant mothers with low-lying placenta should never squat. Observe the condition closely. If heavy bleeding, repeated bleeding, or labor is imminent, termination of pregnancy should be considered depending on the situation.

The cause of placenta previa is usually that if the pregnant mother is of advanced age (over 35 years old), and has uterine malformations, fibroids, scars, etc., the chance of placenta previa will increase. In addition, the chances of this happening are greatly increased for pregnant women who have given birth multiple times or have a history of placenta previa. When a pregnant mother falls into one of the above situations, she should pay more attention.
