Less fetal movement in the second trimester of pregnancy may be related to physiological factors as well as pathological factors such as umbilical cord around the neck and placental abruption.
1. Physiological factors: As the fetus enlarges in late pregnancy, it is inconvenient to move around in the uterus, and less fetal movement may occur. As long as the fetal movement is within the normal range, there is usually no problem.
2. Pathologic factors: including but not limited to the following possibilities.
(1) Umbilical cord factor: the umbilical cord is twisted or tightly wrapped around the neck due to the tumbling and movement of the fetus in the uterus. At this time, the pregnant woman may have no conscious symptoms, but the fetus may suffer from fetal hypoxia and fetal distress due to the obstruction of blood flow, which may lead to less fetal movement and, in severe cases, may result in the death of the fetus.
(2) Placental factors: Due to the occurrence of placental abruption and other diseases, the fetus may suffer from hypoxia, which may lead to less fetal movement in late pregnancy.
If you have less fetal movement in late pregnancy, you must go to the regular hospital for examination to clarify the cause of reduced fetal movement and take appropriate measures.
