What is the reason why the fetus likes to move

The fetus is more active, so frequent fetal movements will occur. When the fetal movement is frequent, pregnant women must pay attention, because frequent fetal movement may be caused by physiological reasons or pathological reasons. If it is caused by pathological reasons, then you must go to the hospital for examination in time. Below we will introduce the reasons for frequent fetal movements and the normal number of fetal movements.

1. Physiological reasons

Frequent fetal movements in late pregnancy are mostly caused by physiological reasons, which can be divided into the following five situations:

1. After a meal, the blood sugar level in the expectant mother's body increases, and the baby also has strength thanks to the mother, so the fetal movement will become more obvious than before the meal.

2. When taking a bath, under warm water, the expectant mother's blood circulation will be smoother, and her body and mind will be more relaxed. This pleasant mood will be conveyed to the baby, so the fetus's activities will become more frequent.

3. In the late pregnancy, the baby can already recognize the mother's voice. He likes to communicate with his parents through dialogue. Therefore, when the expectant mother talks to the baby, the baby will respond and express his feelings through frequent fetal movements.

4. When the fetus is stimulated by music, it will become more fond of "movements", which is a way for the fetus to express joy.

5. Usually the fetus is more active at night. On the one hand, it is because it is more energetic at night. On the other hand, it is because the expectant mother can calm down and feel the baby's fetal movement at this time.

2. Pathological causes

Expectant mothers need to be alert that not all frequent fetal movements in late pregnancy are normal. If the fetal movements have been sparse and suddenly become frequent, you should pay attention, because this may mean that the fetus is lacking oxygen or is being attacked by some disease.

When the fetus suffers from hypoxia, it will become irritable and hyperactive. The number of fetal movements will increase in the early stages of hypoxia. When the intrauterine hypoxia continues to worsen, the fetal movements will gradually weaken and the number of movements will decrease. This is a sign of danger to the fetus. If no emergency measures are taken at this time, the fetus will stop moving and even its heart rate will disappear, and the heart will stop beating, resulting in death. Common hypoxia can be seen in placental abruption, placenta previa, umbilical cord around the neck, etc.

3. How many fetal movements are normal?

The number, speed, strength, etc. of fetal movements can often predict the safety of the fetus in the uterus. Normal fetal movement indicates that the placenta is functioning well, that the oxygen supplied to the fetus is sufficient, that the fetus is developing healthily, and that the little life is living happily in the uterus. If the fetal movement is less than 20 times within 12 hours, or less than 3 times within 1 hour, it often means that the fetus may be suffering from hypoxia, and pregnant mothers should not take it lightly.

The fetal movement is generally 3-5 times per hour, and about 30-40 times in 12 hours. Under normal circumstances, the strength and frequency of fetal movements vary throughout the day and night. The number of movements is less in the morning, increases after 6 pm, and is most active between 8 and 11 pm. This means that the fetus has its own sleep pattern, which is called the fetal biological clock.
