Why is it easier to have a baby while lying on your back?

Women in early pregnancy need to pay special attention to their physical condition. Whether it is diet or lifestyle habits, they need to be guided by scientific methods. Pregnant women often have certain foods that they cannot eat or cannot do strenuous exercise. Sit-ups are a relatively strenuous exercise and may also cause fetal distress. It is particularly harmful to the health of pregnant women, but why is it easy for fetal movement when lying on your back?

Why does the fetus move when lying flat?

For example, when a water bag is laid flat, does the water inside fill up to the surroundings? Yes, the uterus is similar. When you lie flat, the amniotic fluid in the uterus will also flow to the surroundings. The baby will definitely feel it staying inside, and it is normal for it to move and kick. However, don't lie flat for too long, so doctors suggest that you lie on your side, which is good for the baby's health. Under normal circumstances, the pregnant uterus often rotates to the right, causing the uterine artery to twist. The left lateral decubitus position can correct the twisted uterine artery to a certain extent, thereby ensuring smooth uterine blood flow and good placental blood perfusion. Sleeping flat on your back is not only uncomfortable for the expectant mother, but also for the baby in the belly. In the late stage of pregnancy, if the baby lies flat, it will easily cause hypoxia to the baby, so the baby will move more vigorously at this time. After pregnancy, doctors will recommend that expectant mothers sleep on their left side as much as possible. At this time, the baby will be more comfortable when the expectant mother sleeps on the left side. For some expectant mothers who lie flat on their backs, frequent fetal movements may be a reaction to the fetus feeling uncomfortable. It is recommended that expectant mothers try not to lie flat for the sake of their babies!

How should pregnant women lie down?

1. The main sleeping position for pregnant women is lying on the left side, which is beneficial to the oxygen supply to the fetus. It does not mean that pregnant women cannot lie flat on their back or on their right side. It can be adjusted appropriately to increase body comfort. Proper lying flat on their back or on their right side will not cause intrauterine hypoxia and cerebral palsy in the fetus.

2. The baby should be placed in the left side lying position at 8 to 10 months. Because the inferior vena cava is located just to the right of the abdominal spine, if you lie on your right side, the enlarged uterus will not only compress the inferior vena cava, but the uterus will also rotate to the right to varying degrees, pulling the blood vessels and affecting the normal blood supply to the fetus. Lying on the left side can correct the right rotation of the enlarged uterus, reduce the pressure of the uterus on the inferior vena cava, improve blood circulation, increase blood supply to the fetus, and benefit the growth and development of the fetus.

3. It is not advisable to lie on your back in the late pregnancy, otherwise you are prone to supine position syndrome during pregnancy. When lying on your back, the huge uterus compresses the inferior vena cava, which will reduce the amount of blood returning to the heart and cardiac output, and cause hypotension. Pregnant women will feel dizzy, blacking out, palpitations, nausea, shortness of breath, pale complexion, rapid and weak pulse, weakness in the limbs, cold sweats, etc., which is symptoms of supine position syndrome during pregnancy.
