Pregnancy is a long process for women, and it is not easy to conceive a small baby. As the fetus grows larger, the pregnant woman's belly also becomes larger. In addition to the fetus itself, a larger belly is also the amniotic fluid, and the amount of amniotic fluid is also important. So, is it normal for the amniotic fluid to be 55mm at 31 weeks of pregnancy?
At 31 weeks of pregnancy, the amniotic fluid thickness of 55mm is within the normal range, which is considered normal. After the embryo develops to more than ten weeks, obvious amniotic fluid appears. From then on, the fetus lives in amniotic fluid, which has a protective and buffering effect on the fetus. The nutrients and water absorbed by the fetus from the placenta are excreted through the kidneys, bladder, and urethra, and this urine is called amniotic fluid. Amniotic fluid is an important indicator for detecting the health of the fetus.
Both polyhydramnios and oligohydramnios are harmful to the fetus, so as the fetus grows larger, mothers should regularly go to the hospital for examination. Currently, most hospitals use ultrasound to understand the amount of amniotic fluid and use the amniotic fluid index method to determine whether the amniotic fluid volume is normal. Oligohydramnios can cause fetal abnormalities. If the fetal kidney is underdeveloped, it can cause abnormalities such as urethral stricture and oligohydramnios. Oligohydramnios can be increased by drinking plenty of water. In severe cases, it is necessary to go to the hospital, otherwise it will affect the healthy growth of the fetus.
At 31 weeks, the fetus has gradually grown, and its bones and organs have developed more mature and strong. At this point, the fetus can already hear the sounds outside the mother's body, so the mother can talk more to the baby, tell a little story, and listen to prenatal education more, which is beneficial for the healthy growth of the fetus.
