What is the reason for the decrease in fetal movement at 39 weeks of pregnancy?

Some pregnant women report that their fetal movements decrease significantly when they reach the 39th week of pregnancy. Is this a disease? What is going on? Why does the fetal movement decrease? You must learn to detect fetal movements at ordinary times. And if the fetal movement is determined to be wrong for the fetus, you must see a doctor in time. Moreover, why does the fetal movement decrease when you are 39 weeks pregnant and about to give birth?

Normally, the longest time the fetus can remain motionless should not exceed 75 minutes (children don’t sleep too long during their naps). Therefore, if you feel that the fetus has not moved for more than one and a half hours, you should eat some snacks, touch your belly, or even pat your belly, or push the baby, and put a walkman on your belly to play music for him. If you find that the number of fetal movements suddenly decreases or even stops, it indicates that the fetus is in poor health or there is an abnormal problem, and you should go to the hospital for examination as soon as possible. If the fetal movement is less than 20 times within 12 hours, or less than 3 times within 1 hour, it is often because the fetus is lacking oxygen and its life may be seriously threatened. Some people call this phenomenon a "premonition of fetal danger" and pregnant women must not take it lightly. The process from the disappearance of fetal movement to fetal death usually takes about 12 hours to 2 days, and most of the time it takes about 24 hours.

Of course, fetal movement is just a subjective feeling, and can also be affected by the pregnant woman's sensitivity to fetal movement, the amount of amniotic fluid, the thickness of the abdominal wall, and the use of sedatives or drugs such as magnesium sulfate. Therefore, these factors should be excluded when judging the accuracy of fetal movement information. The fetal movement count can only serve as a sign of the fetal safety. As for the development of the fetus, whether there are any deformities or other abnormalities. It is necessary to combine it with other medical instruments and other inspection methods for comprehensive analysis to make an accurate judgment.

Pregnant women can pay attention to observing fetal movements, detect abnormalities in time, and receive timely diagnosis and treatment.

Especially after pregnant women reach a certain stage of pregnancy, especially when they are about to give birth in the 39th week, they must pay special attention to the fetal movement. Some fetuses will have more frequent movements, while others will have less fetal movement after entering the pelvis. If there is a big difference, you can go to the hospital for a detailed examination.
