Patient's question:
I am four months pregnant now. My husband is a person who likes to make friends, and every Sunday he brings a large group of friends to play at home. They all smoke and fight over things, and it's difficult to say anything.Doctor's answer:
In poorly ventilated areas, non-smokers inhale the amount of smoke equivalent to smoking one cigarette in just one hour. Statistics show that people living with smokers have a six times higher risk of developing lung cancer compared to non-smokers. So, what are the dangers of pregnant women inhaling secondhand smoke?Pregnant women who inhale secondhand smoke face the same adverse effects on the fetus as those who smoke.
Women exposed to smoke are more prone to weakened immunity, making them more susceptible to colds, headaches, and even cancer. Pregnant women who smoke more than 10 cigarettes daily have double the miscarriage rate and twice the premature birth rate compared to non-smokers.
During the later stages of pregnancy, there is a higher risk of severe bleeding, which could endanger both the mother and the child.
10% of infant sudden deaths are linked to secondhand smoke.
When tobacco burns, it releases harmful chemicals that can pass through the placenta to "disturb" the innocent baby.
Toxic gases like carbon monoxide reduce oxygen levels in the mother's blood, leading to fetal hypoxia. The addictive drug nicotine in tobacco narrows blood vessels, slowing blood flow, which means less nutrition and oxygen are supplied to the fetus, increasing the risk of premature birth. Premature infants may experience respiratory, digestive, and temperature regulation disorders, and some may even die shortly after birth.
Children born to smoking mothers have a significantly higher risk of low birth weight, which can cause early health problems and is a major cause of infant mortality. 10% of sudden infant deaths are attributed to passive smoking.
Women who smoke during pregnancy have a higher rate of birth defects compared to non-smokers, and their children are more likely to have intellectual disabilities or mental health issues.
Recent studies by scientists show that exposing embryos or young children to secondhand smoke increases their risk of developing asthma and respiratory syndromes later in life. Secondhand smoke accounts for a quarter of adult asthma cases. This was discovered through a 11-year study of nearly 3,000 subjects. In passive smoking environments, embryos and young children are the most vulnerable group, and this harm can persist into adulthood. Therefore, preventing asthma and respiratory syndromes starts with pregnant women, who should avoid secondhand smoke environments.
