How much amniotic fluid is normal at 22 weeks of pregnancy

It is very difficult for a woman after getting pregnant. This is something that every woman must experience. Although it is difficult, it is also very happy. Women at this time are all concerned about the growth and development of the fetus. So how much amniotic fluid is normal for a pregnant woman at 22 weeks of pregnancy? This is a problem that pregnant mothers in the second half of pregnancy are more concerned about. Now follow the steps of the editor to find out.

How much is the standard for amniotic fluid index at 22 weeks of pregnancy

1. Amniotic fluid index: divide the uterine oblique angle into four quadrants with the umbilical straight line and the linea alba as the mark, accurately measure the vertical diameter line of the largest amniotic reservoir in each quadrant, and the sum of the four is the amniotic fluid index. When accurately measuring AFI, please note: if the amniotic reservoir is on both sides of the marking line, only accurately measure the diameter of one side. The normal range of amniotic fluid for the fetus is: 5 to 18 cm.

2. The amniotic fluid of pregnant women is one of the factors to maintain the survival of the fetus. Before the test tube embryo begins to be produced, the amniotic fluid of pregnant women must first expand the solid endometrium and provide the free movement space required for the development of the fetus. Its functions also include: acting as a buffer when the uterus is impacted by external forces, maintaining a stable temperature, analyzing components to understand the health and maturity of the fetus, and when it hurts, the water bag transmits pressure to help dilate the cervix.

How does turbid amniotic fluid occur?

1. The fetus will drink the amniotic fluid of the pregnant woman starting from the 10th week of pregnancy. After drinking the amniotic fluid, it will filter out suspended matter in the intestines and stomach, produce urine through the kidneys, accumulate in the bladder, and then be discharged through the urethra. These residues in the stomach and intestines will be discharged after the newborn is born, and this is meconium.

2. Under normal circumstances, the amniotic fluid of pregnant women is transparent, colorless, and vernix caseosa can be seen. When the fetus excretes meconium into the amniotic fluid of the pregnant woman and causes turbidity, it is called meconium contamination of the amniotic fluid, which is what we usually call turbid amniotic fluid.

The above is the scientific data obtained by the editor based on the normal amount of amniotic fluid in a pregnant woman at 22 weeks of pregnancy. However, don't be too concerned about the growth and development of the fetus. You still need to pay attention to the physical condition of the pregnant mother. You can't ignore the mother's physical condition for the sake of the baby. Also, a reasonable diet and not being picky about food can make the fetus grow and develop healthily.
