Pregnancy cough can have an effect on the fetus because the immunity of pregnant women decreases during pregnancy, which can easily lead to a cold and cough. If the cough is severe it can lead to an increase in abdominal pressure, which can cause fetal miscarriage in the early stage and preterm delivery in the late stage, as well as the possibility of fetal hypoxia. A pregnant woman’s cough needs to be treated promptly. If the cough is mild, it will not have any effect on the fetus and should not be overly anxious. If you have a cough, you should find the cause early and treat it symptomatically, and you must not use medication without permission. Pregnant women should be very careful with medication during pregnancy. They need to be examined by a respiratory unit to find the cause for treatment and should use medication according to the correct doctor’s instructions. During pregnancy coughing should be avoided by inhaling harmful gases, breathing fresh, moist air, not eating contaminated food or fatty, spicy and stimulating food, and coughing patients should have a light diet.
