It is normal for the fetus to experience frequent hiccups during the later stages of pregnancy. The hiccups occur because the baby is basically mature at this time and swallows amniotic fluid during this period. The symptoms of hiccups will promote the baby’s lung capacity, which will promote the maturation of the baby’s fetal lungs and help increase the baby’s blood circulation after birth and enable it to breathe well on its own. During this period you should pay attention to check the fetal heart changes, if the fetal heart is normal and the amniotic fluid is clear and not cloudy, you can leave it alone, it is a natural phenomenon. Try to pay attention to bed rest, relax, and enhance nutrition to promote the growth and development of the fetus. If the fetal heartbeat is not normal during this period, you should check to make sure, and then treat the symptoms.
