When female friends are pregnant, they must never come into contact with alcohol, otherwise it will cause great harm to the fetus. Pregnant women are also not allowed to smoke, and even secondhand smoke must be avoided. Because inhaling second-hand smoke can also cause significant harm. So, what are the hazards of secondhand smoke exposure for pregnant women?
1. Sudden fetal death: If pregnant women frequently inhale second-hand smoke, it is not only harmful to their own health, but also easily leads to sudden fetal death. Moreover, the likelihood of premature birth, neonatal neural tube defects, and cleft lip and palate increases significantly. It can be said that second-hand smoke is very harmful to pregnancy and the fetus in the womb, so pregnant women must try to stay away from such environments as much as possible.
2. Pregnancy complications: Pregnant women who are exposed to secondhand smoke for a long time are greatly affected by the environment, which can easily lead to gestational hypertension. It is also a common factor that causes various pregnancy complications, such as gestational hyperglycemia, which is directly related to secondhand smoke.
3. Premature birth, respiratory and digestive dysfunction: Toxic gases such as carbon monoxide in secondhand smoke can easily lead to a decrease in maternal blood oxygen concentration, which can cause fetal hypoxia. Moreover, the addictive drug nicotine in tobacco can cause vascular stenosis, which in turn slows down blood flow, reducing the supply of nutrients and oxygen to the fetus, making it easy for the fetus to experience premature birth.
