The placenta is the connection between the fetus and the mother, and all nutrients and oxygen supply to the fetus need to be achieved through the placenta. Generally speaking, the placenta can be divided into four levels based on its maturity, and different levels of placental maturity indicate the health of the placenta. So is it good for the placenta to show primary changes at 14 weeks of pregnancy?
The placenta will gradually mature with the progress of pregnancy, and when it reaches a certain level of maturity, its function will decline, just like aging, unable to provide nutrition and oxygen to the fetus normally. The placental maturity grading is a standard used to measure the maturity of the placenta, usually divided into four levels, as follows:
The maturity of the placenta is divided into four levels: level 0, level 1, level 2, and level 3.
Grade 0 indicates that the placenta is not yet mature: usually in mid pregnancy, around 12-28 weeks of gestation.
Level 1 marks the early stage of placental maturation: 30-32 weeks of pregnancy, the early stage of placental maturation, which can also transport nutrients to the fetus.
Level 2 marker: The placenta has matured: usually after 36 weeks of pregnancy, the placenta is approaching Changshu.
Level 3 marker: The placenta has aged, and due to calcification and cellulose deposition, its ability to transport oxygen and nutrients is reduced, putting the fetus at risk at any time.
Everyone's placental maturity is different: mid pregnancy (12-28 weeks) - placenta grade 0; Late pregnancy (30-32 weeks) - placental grade 1; After 36 weeks - placenta grade 2 (relatively mature). If placenta grade 3 is found before 37 weeks and combined with biparietal diameter values and an estimated fetal weight of 2500 grams, placental precocity should be considered and the possibility of intrauterine growth retardation should be alerted. At 38 weeks, the placenta enters grade 3, indicating placental maturation.
Through the introduction of this article, it can be known that the placenta should remain at grade 0 at 14 weeks, but now the placenta has shown a grade 1 state, which is an abnormal state. If you are a 14 week pregnant woman with such placental maturity, it is best to carefully refer to the content of this article.
