When can the fetus' position be fixed? How to adjust the abnormal fetal position?

We all know that after a woman becomes pregnant, the fetus will continue to grow and develop in the mother's belly. When it grows to a certain stage, the fetus will often move, which is called fetal movement. Therefore, the position of the fetus is not fixed in the early pregnancy. So when will the position of the fetus be fixed? Let's take a closer look!

When can the fetal position be fixed?

The so-called fetal position, simply put, is the posture of the baby in the uterus.

For a normal birth, the most suitable fetal position is the head position, which is the position with the head down and the feet up. Other positions such as the breech position (with the head up and the feet down) and the transverse position are not suitable for a normal birth. If you force a normal birth, it is likely to cause a difficult birth or the baby to suffocate due to lack of oxygen.

Therefore, fetal position is a very important factor.

As for when the fetal position can be fixed, it is generally around 28 weeks of pregnancy, which is about 7 months. The baby has grown very big at this time, and even if the mother's belly becomes very big, it still seems a little small for them. The cramped space will gradually make the baby's position become fixed, and as they grow up, the chance of changing their position will be small.

What to do if the fetus is in an abnormal position

1. Lift your buttocks

Pregnant women lie on their backs with their knees bent, and put four pillows or cushions under their hips to make the pelvis higher than the abdomen. Because the pelvis is higher than the abdomen, the fetal head can float up, stimulate the fetus, and rotate the fetal head to move upward and enter the pelvis. This action is relatively simple and can be done by most pregnant women, 10 minutes each time, twice a day.

2. Knee-chest position correction method

Empty your bladder, loosen your belt, and lie on a hard bed, with your knees on the bed, your hips raised high, your thighs perpendicular to the bed, and your chest as close to the bed as possible. Do this for 15 minutes, once in the morning and once in the evening, for a week.

3. In vitro translocation

If the rotation fails before 37 weeks of pregnancy, some obstetricians will perform an external rotation, massaging the pregnant woman's abdomen to slowly turn the fetus. This method is not dangerous. The ideal external rotation is between 37 and 38 weeks of pregnancy, when there is still enough amniotic fluid to allow a small amount of movement, and the success rate is 50% to 70%.

4. Moxibustion

The acupoints for moxibustion of malposition of the fetus are mainly Zhiyin acupoints, which are applied between 15:00 and 17:00 in the afternoon. After emptying the bladder, lie on your back, take off one side of the socks, relax the muscles of the whole body, close your eyes naturally, and imagine the fetus in the abdomen turning.

Causes of malposition of fetus

1. The amount of amniotic fluid in the expectant mother's uterus is too much or too little. The amount of amniotic fluid determines whether the fetus's range of movement in the uterus is too large or too small.

2. The expectant mother's abdominal wall is loose. The loose abdominal wall causes the abdominal muscles to have less support for the uterus, causing the uterus to relax.

3. Uterine diseases, such as congenital uterine developmental abnormalities and intrauterine tumors.

4. The umbilical cord is too short, making it impossible to absorb enough nutrients. The fetus is small and has a large range of movement, resulting in an abnormal fetal position.
