A violent cough in the middle of pregnancy usually does not shock the fetus, but if the cough is so violent that it has caused a large change in the pressure of the uterine cavity, it may have some effect on the fetus. The fetus is located in the uterine cavity and there is a certain amount of amniotic fluid in the cavity. When a pregnant woman coughs violently, the uterine wall and the amniotic fluid can play a good role in cushioning and protecting the fetus, which in turn usually does not cause shock to the fetus. However, if a violent cough causes a sudden increase and decrease in abdominal pressure, resulting in a change in abdominal pressure and a large change in uterine cavity pressure, it can easily cause premature rupture of the fetal membranes, premature abruption of the placenta or uterine contractions, which may result in preterm labor or miscarriage. Therefore, when a violent cough occurs, it is recommended that pregnant women control their strength appropriately and protect their abdomen with their hands, which may have the effect of slowing down the rapid changes in abdominal pressure to a certain extent. For pregnant women with a severe cough, it is also necessary to clarify whether the cause of the cough has an impact on the fetus. In most cases, the cough is caused by upper respiratory tract infections or bronchial or lung inflammation, and when the cough is severe, oral cough suppressants and antibiotics can be administered under the guidance of a doctor for symptomatic treatment, and nebulized inhalation can be taken if necessary. If you want to know if the fetus is affected, you can go to the hospital for an ultrasound examination to check the condition of the fetus.
