Cold and cough during pregnancy can still have some effect on the fetus. Because colds are mostly acute upper respiratory tract infections caused by viral or bacterial infections, the infected virus or bacteria in the body will enter the fetus with the blood circulation, which can lead to congenital diseases if the fetus does not have a strong resistance. In addition, coughing during this period can also have an effect on the fetus, as coughing can increase abdominal pressure and lower the placenta, and violent coughing may cause the fetus to miscarry. Therefore, we recommend active symptomatic treatment, such as oral oseltamivir capsules for antiviral treatment and diphenhydramine hydrochloride tablets to relieve coughing. At the same time, monitor the body temperature and provide timely antipyretic treatment, pay attention to rest, prevent getting cold, and eat less spicy and stimulating food to avoid aggravating the symptoms of cough.
