Will the fetus be deprived of oxygen in early pregnancy?

In the early stages of pregnancy, the fetus is often affected by various factors. Pregnant women should always pay attention to changes in their bodies in the early stages of pregnancy, and seek timely treatment if they feel uncomfortable. Pregnancy check-ups are very necessary, and you should replenish your body's energy. Fetal hypoxia is actually a very serious condition. So will the fetus suffer from hypoxia in early pregnancy?

Will the fetus be deprived of oxygen at 21 weeks of pregnancy?

Fetal hypoxia mainly occurs in the late stages of pregnancy. If the pregnant mother suffers from anemia that causes the blood oxygen level to be too low, suffers from gestational hypertension, diabetes, asthma, heart disease or kidney disease, or the umbilical cord is not supplying enough oxygen, the baby is likely to show signs of hypoxia in the mother's body, which can cause fetal growth retardation, decreased fetal movement and other problems. In severe cases, it can even lead to fetal death.

Therefore, the possibility of fetal hypoxia at 21 weeks of pregnancy is relatively small, but it should not be taken lightly. What should I do if fetal hypoxia occurs?

First, if fetal hypoxia occurs, especially severe hypoxia leading to fetal growth retardation. Some mothers think that since the baby is still young, it is better for him to stay in the womb for a longer time. However, obstetricians will analyze the reasons why the fetus is small. If it is due to poor placental function and intrauterine fetal hypoxia, it means that the intrauterine environment can no longer provide the baby with sufficient nutrition. The mortality rate will be higher if the baby stays in the womb for one more day. Therefore, it is necessary to comprehensively evaluate and analyze the baby's risk of premature birth in utero and after birth, and determine a relatively appropriate gestational age for delivery.

Second, we must pay attention to the problem of fetal intrauterine hypoxia. The answer to this question is as follows: If the baby is hypoxic in the uterus, it will manifest as abnormal increase in fetal movements in the early stage, decrease in fetal movements in the later stage, and early increase in fetal heart rate and later decrease in fetal heart rate. If it is more serious, the possibility of fetal death cannot be ruled out. In the treatment of fetal intrauterine hypoxia, the first thing to do is low-flow oxygen inhalation and correction of the cause of fetal hypoxia. Common causes include oligohydramnios or umbilical cord around the neck, etc. Specific examinations require B-ultrasound. If the fetus is in a state of hypoxia for a long time in the womb, it will affect the development of the fetal brain and may even cause cerebral palsy in the baby.

Third, if fetal hypoxia occurs, especially severe hypoxia leading to fetal growth retardation. Some mothers think that since the baby is still young, it is better for him to stay in the womb for a longer time. However, obstetricians will analyze the reasons why the fetus is small. If it is due to poor placental function and intrauterine fetal hypoxia, it means that the intrauterine environment can no longer provide the baby with sufficient nutrition. The mortality rate will be higher if the baby stays in the womb for one more day. Therefore, it is necessary to comprehensively evaluate and analyze the baby's risk of premature birth in utero and after birth, and determine a relatively appropriate gestational age for delivery.

What are the symptoms of fetal intrauterine hypoxia?

During pregnancy, the uterus continues to grow and takes up more and more space, which puts more pressure on the diaphragm and causes difficulty breathing. Increased progesterone levels can also speed up your breathing. The increase in oxygen demand in the body forces pregnant women to breathe faster.

1. Changes in fetal movement: Fetal movement is a normal physiological activity of the fetus and can be felt by pregnant women at 18-20 weeks of pregnancy. Fetal movement varies from fetus to fetus. Generally, if the fetal movement is less than 10 times/12 hours or more than 40 times/12 hours, it indicates that the fetus may be suffering from intrauterine hypoxia. This is because the fetus is trying to reduce oxygen consumption or because hypoxia affects the central nervous system.

2. Abnormal fetal heart rate: The normal fetal heart rate is 120-160 beats per minute and is very regular. Before the fetal movement decreases, the fetal heart rate becomes too frequent. If it exceeds 160 beats/minute, it is a signal of early fetal hypoxia. If the fetal movement decreases or stops, and the fetal heart rate is less than 120 beats/minute, it is a late stage of fetal hypoxia.

3. Growth arrest: The growth of the fetus will also slow down after hypoxia. Fetal growth can be determined by measuring the height of the uterine fundus. Under normal circumstances, the diameter of the breasts should increase by about 1 cm per week after the 28th week of pregnancy.
