How much drinking causes Fetal Alcohol Syndrome? Alcohol consumption, even in small amounts, can cause FAS. Alcohol is a teratogenic substance that easily penetrates the placenta and causes damage to the fetus. It restricts the growth of the brain and other organs. Maternal alcohol consumption is a well-established contributor to fetal complications such as abortion, stillbirth, premature delivery, and low birth weight¹. Other than these, the most severe consequence of drinking while expecting is the risk of fetal alcohol syndrome (FAS).
There are 3 ways to safely get alcohol out of your system fast, but medically supervised detox is a requirement. ChoicePoint is the right choice for pregnant women as we provide a personalized program and all the support a mother needs. Whether you want to quit alcohol, require therapy, or are looking for aftercare programs. Feel free to call 844.445.2565 for assistance.

What is Fetal Alcohol Spectrum Disorder (FASD)?
Fetal Alcohol Spectrum Disorder (FASD) describes a range of conditions that occur in an individual whose mother consumed alcohol during pregnancy². These conditions include physical problems, cognitive and behavioral impairments, or a combination of all these issues. FASD includes various conditions:
- Fetal Alcohol Syndrome (FAS)
- Partial Fetal Alcohol Syndrome (pFAS)
- Alcohol Related Neurodevelopmental Disorder (ARND)
In this blog, our primary focus is on Fetal Alcohol Syndrome (FAS).
Fetal Alcohol Syndrome (FAS) Is Different from FASD?
FAS is the most severe form of Fetal Alcohol Syndrome Disorder. In extreme cases, fetal death occurs from alcohol consumption. Alcohol passes from the mother’s bloodstream to the fetus via the umbilical cord. The fetus cannot metabolize alcohol, so it stays in the body for a longer time.Children born with FAS have a disrupted central nervous system, growth retardation, altered facial features and intellectual impairment. Alcohol consumption has damaging impacts on the developing fetus. Even too much alcohol consumed 3 months before the pregnancy can affect the fetus³. FAS occurs when the expecting mother consumes alcohol in the form of beer, whiskey, wine, and hard cider. Without alcohol, FAS does not happen.

Side Effects Of Abusing Alcohol While Expecting A Child
How Many Drinks Can Cause Fetal Alcohol Syndrome?
Healthcare practitioners advise not to consume any amount of alcohol during pregnancy. However, the intake of higher levels of alcohol by the expectant mother causes severe forms of Fetal Alcohol Spectrum Disorder (FASD)⁴. According to the National Institute of Alcohol Abuse and Alcoholism (NIAAA), the impacts of alcohol consumption on the fetus are primarily influenced by the following 5 common factors:
1. Amount of Alcohol Consumed
Although no amount of alcohol is considered safe during pregnancy, regular drinking increases and how long does alcohol stay in your system also increases the chances of harmful effects on the fetus, such as cardiac defects and immature brain development.
2. Pattern of Drinking
Frequent and heavy drinking throughout pregnancy caused FAS.
3. Genetic Makeup
Genetic variations of the mothers determine how their bodies are going to process alcohol, fetal development, and the effect of alcohol on the mother.
4. Maternal Health Condition
Pregnant women’s health and nutrition can not be a direct controlling factor for FAS⁵. However, good overall maternal health conditions can minimize the risks of FAS. For instance, managing pre-existing health issues like hypertension, which have an impact on fetal well-being, and promoting maternal care, including shunning alcohol.
5. Exposure During the Pregnancy Stages
How many weeks pregnant does alcohol affect the fetus? Alcohol consumption during different pregnancy stages has varying impacts on the fetus.
- First Trimester: The first trimester is considered the most critical stage of fetal development. Alcohol consumption at any stage of pregnancy can hinder brain development, causing serious mental health disorders in the children. Heavy drinking during the first trimester can cause structural defects such as stunted facial development and cardiac defects.
- Second Trimester: alcohol consumption during the second trimester leads to disrupted development and, in extreme cases, causes abortion.
- Third Trimester: Drinking during the third trimester causes behavioral and cognitive issues.

Executive Clinical Director at ChoicePoint
Is it possible for someone to have fetal alcohol syndrome, even if they don't show any signs of having it?If the mother is drinking alcohol during pregnancy, the child will likely have FAS. In a situation where the child has FAS but does not show any signs, such a condition is known as Fetal alcohol Effect (FAE). FAE is considered more severe than FAS because, in the case of FAS, signs are apparent in the form of abnormal features. Whereas with FAE, signs and symptoms aren’t visible, so they are expected to behave like normal individuals”
How to Diagnose Fetal Alcohol Syndrome (FAS)?
It becomes difficult to diagnose FAS as there are no accurate tests for FAS. It is often observed that expecting women give a vague history of their alcohol consumption during pregnancy. However, pediatrics can often make a successful diagnosis by judging apparent signs and symptoms, including underdeveloped facial features, the alcohol use history of the child’s mother, and low birth weight and behavioral and cognitive issues (hyperactivity, short attention span, and poor judgment).
How Can FAS Be Prevented? 4 Major Precautions
To prevent FAS, you simply have to quit drinking. Below are some practical tips that might help you get rid of alcohol addiction:
1. Stay Away From Alcohol During Your Childbearing Years
If you are aged 15 to 49 years and sexually active, you might have an unplanned pregnancy. In this case, it is advisable to stay away from alcohol. Alcohol consumption can cause damage in the initial weeks of pregnancy.
2. Say No to Alcohol if You Are Trying to Conceive
If you are planning to conceive, don’t drink at all. If you’re pregnant and you haven’t quit alcohol consumption, stop as soon as possible. The sooner you say no to drinking, the better it is for the fetus.
3. Avoid Alcohol at All Stages of Pregnancy
All three trimesters of pregnancy are crucial. Don’t even go close to alcohol during any of the stages. FAS can be prevented in children whose mothers don’t consume alcohol during pregnancy.
