The effect of maternal fever on the baby should be decided according to the specific situation, if it is a transient low fever usually does not cause harm to the baby, if it is a high fever and fever for a long period of time may cause fetal malformation, miscarriage and premature birth, neurological damage.
1. Fetal malformation: If the fever exceeds 39 ℃ in early pregnancy, the fever may be caused by bacterial or viral infection, and the pathogen may pass through the placenta, which may interfere with the normal differentiation and development of fetal cells and cause fetal malformation.
2. Miscarriage and preterm labor: maternal fever can cause fetal heart rate to be too fast, and high fever can also stimulate the uterus to cause uterine contractions, leading to miscarriage or preterm labor.
3. Neurological damage: If the fetus is in the period of neural tube development, maternal fever may cause damage to the fetal nervous system, increasing the chance of fetal neural tube malformation.
Pregnant women with fever should consult the doctor in time, complete the relevant examinations to clarify the cause of the disease, and under the guidance of the doctor’s treatment.
