Old coughing in pregnancy, when the coughing symptoms are mild, usually does not affect the fetus too much. If a pregnant woman coughs violently, it may lead to the problem of miscarriage, but fetal arrest may also be caused by the presence of other abnormalities in the pregnant woman herself. Fetal arrest means that the embryo in the uterus stops developing normally, and an ultrasound examination shows that the gestational sac in the uterus is withered, or the fetal bud or fetus is incomplete, and there is no fetal heartbeat, suggesting miscarriage or stillbirth. In the case of violent coughing, the uterus may contract as a result of violent exertion, which may lead to preterm labor or miscarriage. In addition to prolonged and violent coughing infections with respiratory diseases that may lead to fetal abortion, it can also be related to chromosomal or genetic abnormalities of the embryo, or to maternal infections, uterine malformations and the consumption of special drugs by the pregnant woman. Even if the fetus has already stopped, it is necessary to consult a doctor in time to find out the cause of fetal stoppage, and timely surgery is needed to separate the fetus from the mother’s body to ensure the safety of the mother. Pregnant women are prone to decreased resistance during pregnancy, leading to viral and bacterial infections, so pregnant women need to pay attention to adequate rest and warmth to prevent colds. It is best not to overexert yourself when coughing. If you cough frequently, you can use medication to relieve it, but it is best to consult your doctor first and not to use stimulant medication.
