Pregnant women in the 6th month of pregnancy with a cold and cough may have an effect on the fetus. Some viruses and bacteria can enter the fetus directly through the placenta. 6 months of pregnancy is a critical period for the development of fetal organs, and infection at this time may affect the growth and development of the fetus, causing congenital heart disease, cleft lip, hydrocephalus and anencephaly in severe cases. In addition, a cold and cough can stimulate uterine contractions and cause signs of preterm miscarriage. After pregnancy, the body’s immunity is lowered and it is easier to catch a cold than usual. If you have a mild cold and no other symptoms, you can start without medication, pay attention to rest, drink more water, eat a light diet and avoid irritating your throat, which can effectively solve the discomfort. If it is a severe cold and cough, it is recommended to consult a doctor promptly and inform him/her of the pregnancy, and he/she will prescribe medication at his/her discretion. If left untreated, it may affect the growth and development of the fetus. Pregnant women are advised to go outdoors properly, strengthen nutrition, improve body immunity, pay attention to cold and warmth, and prevent colds. Have regular maternity checkups to keep abreast of the growth and development of the fetus in the body.
