I am 38 weeks pregnant. When I was 37 weeks pregnant, I went for a check-up and the baby weighed 2900g. Now, when I go for a routine check-up at 38 weeks, it has dropped to 2750g. So, doctor, can you tell me if a 38-week-old fetus has lost weight? What should I do to improve this situation, doctor? Thank you, doctor.

Depending on the stage of pregnancy, low amniotic fluid will have different effects on the development of the fetus. Pregnant mothers need to understand these effects to make wise decisions in the treatment of low amniotic fluid.

The phenomenon of umbilical cord around the neck, also known as umbilical cord around the neck, occurs when the fetus has the umbilical cord wrapped around the neck. This phenomenon can occur at any time during pregnancy or during labor or during the birth process.

Abnormalities in the color and volume of amniotic fluid can be acute or chronic, due to physiological or pathological causes. Amniotic fluid abnormalities can increase the risk of morbidity and mortality for both mother and baby.

About 1% of pregnant women experience polyhydramnios. If not detected and treated promptly, polyhydramnios can cause dangerous complications for both mother and baby.

Amniotic fluid has the function of nourishing and protecting the fetus throughout pregnancy. The volume of amniotic fluid changes according to each stage of fetal development. By examining the volume of amniotic fluid, the doctor can assess the health status and some diseases of the fetus.

According to statistics, about 1% of pregnant women are at risk of facing the problem of excess amniotic fluid. The condition of excess amniotic fluid usually occurs from the 30th week of pregnancy onwards, however, there are cases where the fetus has excess amniotic fluid at 20 weeks.

Polyhydramnios is the phenomenon of excess accumulation of amniotic fluid beyond normal levels. Amniotic fluid plays an extremely important role in the development of the fetus, however, excess amniotic fluid can potentially pose some risks and affect the mother and fetus, especially for pregnancies in weeks 37-39.

Polyhydramnios is a condition of excess accumulation of amniotic fluid exceeding the normal amniotic fluid index. Amniotic fluid plays an extremely important role in the development of the fetus, however, excess amniotic fluid can potentially pose some risks and affect the mother and fetus.

Almost every pregnant woman is asked to measure the AFI index - amniotic fluid index - when going for a prenatal check-up to monitor the amount of amniotic fluid, to prevent cases of insufficient or excess amniotic fluid during pregnancy. In particular, the condition of excess amniotic fluid at 31 weeks of pregnancy or excess amniotic fluid at 32 weeks, excess amniotic fluid at 35 weeks all have more or less impact on the fetus and mother.

According to statistics, the rate of umbilical cord knotting accounts for 0.3 - 2.2% of pregnancies and the mortality rate of fetuses with this condition is often 4 times higher than that of normal pregnancies. Therefore, umbilical cord knotting is a danger that "threatens" millions of pregnant mothers in our country and around the world. Recognizing the signs of umbilical cord knotting on ultrasound early will help pregnant women take timely measures.
