Alcohol and Pregnancy
Alcohol is a teratogen
A teratogen is a drug, chemical or infection that interrupts or alters the normal development of a fetus, including development of the brain or other major organs. Other examples of teratogens include Rubella, radiation, mercury and thalidomide.
There is no safe amount or safe time to drink alcohol during pregnancy which is why we recommend ...
"NOT DRINKING ALCOHOL IS THE SAFEST OPTION"
Alcohol can cross the placenta
The placenta links the blood supply of the fetus to the blood supply of the mother and is essential to the growth of a healthy fetus. The placenta cannot keep harmful substances such as alcohol away from the fetus which is why we recommend 'no alcohol in pregnancy is the safest option'.
Because the fetus lacks the ability to process the alcohol as the liver is not fully formed, they absorb the alcohol and can have the same blood alcohol content or higher than the mother and it remains at that level for a longer period of time.
In 2009 the National Health and Medical Research Council (NHMRC) released an updated version of the Australian Guidelines to Reduce Health Risks from Drinking Alcohol. These guidelines aim to communicate evidence concerning these risks to the Australian community to allow individuals to make informed decisions regarding the amount of alcohol they choose to consume.
Guideline 4: Pregnancy and breastfeeding
Maternal alcohol consumption can harm the developing foetus or breastfeeding baby.
- For women who are pregnant or planning a pregnancy, not drinking is the safest option.
- For women who are breastfeeding, not drinking is the safest option.
The NHMRC Australian Guidelines to Reduce Health Risks from Drinking Alcohol (page 78) conclude:
- Not drinking alcohol is the safest option.
- The risk of harm to the fetus is highest when there is high, frequent, maternal alcohol intake.
- The risk of harm to the fetus is likely to be low if a woman has consumed only small amounts of alcohol before she knew she was pregnant or during pregnancy.
- The level of risk to the individual fetus is influenced by maternal and fetal characteristics and is hard to predict.
What are the possible effects of fetal alcohol exposure?
Drinking alcohol during pregnancy can result in Fetal Alcohol Spectrum Disorders (FASD) and lifelong disabilities for a person. The damage to the brain can result in problems with:
- communication skills
- everyday living and socialising skills
These disabilities can lead to secondary problems such as:
- poor school performance
- drug and alcohol abuse
- mental health problems
- encounters with the justice system
Diagnosis of conditions within the fetal alcohol spectrum can:
- improve social, health and educational outcomes
- optimise functioning through modification of physical and social environments
- decrease the risk of secondary disabilities through the identification of a child's specific areas of need
Without diagnosis and interventions this may lead to a cycle of welfare dependency and hardship which can impact on the next generation of children, socially and economically.
