Effects of a cold on the fetus during pregnancy

If you catch a cold when you are about eight months pregnant, it will definitely have some impact on your fetus to a certain extent, but as long as you do not abuse drugs, it will not have much impact, nor will it cause any deformities in the fetus during its growth and development. For some pregnant women with more serious colds, they can take appropriate life care measures to improve their physical condition and improve their quality of life.

If a pregnant woman catches a cold, it is important to figure out what causes the cold and at what stage of pregnancy the cold occurs. Different causes and onset periods of colds have different effects on the fetus.

Colds are divided into common colds and viral colds. If it is just a common cold, the main symptoms are sneezing, nasal congestion, and no fever. The symptoms are mild and there is no need to take cold medicine. It can usually heal on its own within a week. In this case, a pregnant woman's cold will not have any effect on the fetus.

If the cold symptoms are severe, especially if the high fever persists and if the cold is caused by influenza virus infection, the cold may have a certain impact on the fetus.

These influences come from:

Colds caused by influenza viruses may cause influenza viruses to infect the fetus;

The medicines you take when you have a severe cold may have an impact on the fetus;

The probability of severe symptoms of influenza during pregnancy is 3.1 times higher in the first trimester, 6.6 times higher in the second trimester, and 7.9 times higher in the third trimester. At the same time, the fetal mortality rate during influenza during pregnancy increases by 1.9 times, and the malformation rate increases by 2.2 times.

Fever will also have a certain impact on the fetus.

Generally speaking, a cold in early pregnancy has a relatively greater impact on the fetus. Because this period is a critical period for the development of various organs of the fetus, influenza virus or cold medicines may cause malformations to the fetus at this period, such as congenital heart disease, cleft lip, hydrocephalus, anencephaly and microcephaly. In severe cases, termination of pregnancy may be recommended.

The impact of a cold in the second and third trimesters on the fetus is relatively small, because the fetus's various organs are basically formed during this period and rarely cause adverse effects. However, if a severe cold occurs during this period, prolonged high fever will hinder the development of the fetus in the uterus. If it is in the late pregnancy, extreme coughing may also cause early rupture of membranes or even premature birth.
