Amniotic fluid in pregnancy

We know that amniotic fluid is fluid that surrounds the baby, and much is said during pregnancy, since we can examine it to know the karyotype of the baby and diagnose possible chromosomal diseases; but above all with regard to childbirth: when we break water we must check whether the liquid is clear or not.

However, today we are going to discuss curiosities of this important liquid.

In the first trimester, this liquid is an ultrafiltrate of the maternal blood plasma, and its composition is very similar, but from week 12, the baby also intervenes in its production and quantity with the filtering of his kidney. It is known that from week 18 or 20 the 90% of amniotic fluid is produced by the baby: the fetus fills its bladder every half hour and empties it, thus renewing the liquid several times a day.

The composition of the amniotic fluid changes throughout pregnancy, it closely resembles maternal plasma and the degree of salinity it presents is similar to seawater.

- Serves as a shock absorber: protects you from external injuries and prevents damage from the pressure exerted by your own organs.

- Keeps the baby at the temperature of the mother's body.

- Helps develop the lungs.

- Allows you to move freely.

- Prevents compression of the umbilical cord

- Provides ions and proteins.

Around week 34 or 36 of pregnancy we have the maximum amount of fluid, between 800-1000 ml. From week 38 on that amount begins to decrease, that is why the gynecologist will check the amount of fluid through ultrasound.

In many cases of alteration in the amount of amniotic fluid, pregnancies end with healthy babies and mothers; No problem.

However, the excessive amount (polyhydramnios) or insufficient (oligoamnios) require a more exhaustive medical control since they may indicate some pathology of the mother, the placenta or the baby such as gestational diabetes, malformations in the fetus, non-functioning placenta, fissure of the bursa, problems in the kidney system of the baby, etc.
