How does a cold in pregnant women affect the fetus?

The impact of a cold on the fetus during pregnancy needs to be evaluated based on the severity and type of the cold. Generally, common colds have minimal effects on the fetus. However, if the cold is caused by a viral infection, it may potentially affect the fetus. Specifically, a severe cold during early pregnancy might allow the virus to pass through the placenta into the fetal body, affecting fetal organ development and increasing the risks of congenital heart defects, cleft lip, hydrocephalus, and microcephaly. Additionally, high fever and toxins resulting from metabolic disturbances may stimulate uterine contractions, leading to miscarriage or premature birth.

Therefore, pregnant women with a cold should seek timely medical attention and follow the doctor's recommendations for treatment, avoiding self-medication. At the same time, maintaining healthy lifestyle habits, such as balanced nutrition, moderate exercise, and sufficient rest, can enhance immunity and reduce the likelihood of catching a cold. Pregnant women should take colds seriously to ensure the health of both mother and baby.
