Whether a pregnant woman’s cough has an effect on the fetus depends on the cause of the cough and its severity. The first thing to consider in a pregnant woman’s cough is the possibility of an infectious disease, and then we have to exclude the possible effects of infectious fever on the fetus, such as chorioamnionitis. In terms of coughing itself, frequent and violent coughing may cause severe changes in abdominal pressure, and if it is combined with some abnormalities, it may cause premature rupture of the fetal membranes, placental abruption, bleeding and other more serious conditions. Therefore, if you have a cough during pregnancy, you should go to the hospital in time to identify the cause and follow the medical advice for treatment. During the treatment period, you should strictly follow the doctor’s instructions and should not take any medication on your own, nor should you increase the amount of medication to avoid any adverse effects on the development of the fetus. When a pregnant woman has a mild cough, she can drink ice sugar pear water and drink 1-2 cups a day to help relieve cough symptoms. You can also drink light salt water in moderation. Light salt water can prevent laryngitis, respiratory infections and bronchitis, etc. Eat vitamin-rich vegetables and fruits to improve your body’s immunity.
