What are the effects of tobacco, alcohol and drugs on pregnancy?One article answer

Smoking during pregnancy will expose the fetus to many harmful chemicals.Nicotine is just one of the 4,000 toxic chemicals that are harmful to the fetus.


Nicotine narrows blood vessels, so the oxygen and nutrients transported to the fetus will become less.Nicotine hurts the fetus’s brain and lungs, and these damage is permanent.

If smoking during pregnancy, the chance of pregnancy complications will increase a lot.It may also cause premature birth; the incidence of various complications is also higher; it is more likely to cause delay in the development of the internal fetus; the fetus is lighter at birth, and it is smaller than the babies born of pregnant women who do not smoke.

Moreover, they are more likely to have hernia (because they can’t control crying), and these infants have increased risk of sudden infant death syndrome (SIDS), and they are more likely to suffer from asthma and obesity during childhood.


If you usually smoke, you should stop smoking once you find that you are pregnant.

Second -hand smoke is the smoke you smoked by others.Sucking second -hand smoke will increase the risk of babies who are born low.The risk of sudden infant death syndrome in infants in contact with second -hand smoke increased.

These babies are more likely to suffer from asthma and ear infections. If someone lives or work, please move one step to avoid inhaling second -hand smoke.

Some people use electronic cigarettes as alternatives of traditional cigarettes.Electronic cigarettes also contain harmful nicotine. Electronic cigarettes are not safe cigarette substitutes and should not be used during pregnancy.


Alcohol can affect the normal growth of the fetus and cause birth defects.During pregnancy, babies may experience physical, intelligence, behavior, and learning disabilities in the future, which may continue for a lifetime.


The more severe disease is fetal alcohol syndrome (FAS).FAS can cause growth problems, intellectual obstacles, behavior problems, and facial features.

FAS is likely to happen to women who drink a lot of alcohol during pregnancy, but drinking alcohol is also harmful, so it is best not to drink during pregnancy.

Some prescription drugs are safe during pregnancy, but some are not.Do not stop the drugs that have been taken for a long time before discussing with your attending doctor.


If the drug you take is risky for pregnancy, your obstetrician may adjust the dose of medication, or it is recommended that you use more safer drugs during pregnancy.

Before taking any non -prescription drugs, contact your obstetrician to give you some suggestions for the safety of pregnant women.
