Cloudy amniotic fluid may have an effect on the fetus. If it is mildly cloudy and the fetal heart monitoring is normal, its effect is negligible. Normal amniotic fluid is a colorless, clear liquid containing more than 90% water, minerals, uric acid, fetal lipids and fetal epithelial cells. If cloudy amniotic fluid occurs, there are more causes, which may be related to amniotic fluid fecal contamination, intra-amniotic cavity infection, maternal cholestasis, etc. In addition, it is also common for the fetus to shed too much fetal fat and float in the amniotic fluid, making the amniotic fluid appear cloudy in appearance, but it will not affect the fetus, so the pregnant woman needs regular maternity checkups at this time. If there is abnormal fetal movement and fetal heart monitoring indicates fetal hypoxia, it may cause fetal distress and fetal fecal aspiration syndrome, and the pregnancy should be terminated at the right time. When a pregnant woman has cloudy amniotic fluid, don’t worry too much, keep regular maternity checkups to monitor the growth of the fetus and deal with abnormal conditions in time.
