Effect of drinking while pregnant

Drinking alcohol while pregnant - NHS

Experts are still unsure exactly how much – if any – alcohol is completely safe for you to have while you're pregnant, so the safest approach is not to drink at all while you're expecting.

Is it safe to drink alcohol when pregnant?

The Chief Medical Officers for the UK recommend that if you're pregnant or planning to become pregnant, the safest approach is not to drink alcohol at all to keep risks to your baby to a minimum.

Drinking in pregnancy can lead to long-term harm to the baby, with the more you drink, the greater the risk.

How does alcohol affect my unborn baby?

When you drink, alcohol passes from your blood through the placenta to your baby.

A baby's liver is one of the last organs to develop and does not mature until the later stages of pregnancy.

Your baby cannot process alcohol well, and exposure to alcohol can seriously affect their development.

Drinking alcohol during pregnancy increases the risk of miscarriage, premature birth and your baby having a low birthweight. It can also affect your baby after they're born.

Drinking during pregnancy can cause your baby to develop a serious condition called foetal alcohol spectrum disorder (FASD).

FASD can cause problems with:

learning and behaviour
joints, bones, muscles and some organs
managing emotions and developing social skills
hyperactivity and impulse control
communication, such as problems with speech

The risk is likely to be greater the more you drink.

How to avoid alcohol in pregnancy

It may not be as difficult as you think to avoid alcohol completely during pregnancy, as many women go off the taste of alcohol early in pregnancy.

Most women do give up alcohol once they know they're pregnant or when they're planning to become pregnant.

Women who find out they're pregnant after already having drunk in early pregnancy should avoid further drinking.

However, they should not worry unnecessarily, as the risks of their baby being affected are likely to be low.

If you're concerned, talk to a midwife or doctor.

What is a unit of alcohol?

If you do decide to drink when you're pregnant, it's important to know how many units you are consuming.

One UK unit is 10 millilitres (ml) – or 8 grams – of pure alcohol. This is equal to:

just under half a pint of cider (218ml) at 4.5% alcohol by volume (ABV: you can find this on the label)
just under half a pint of beer (250ml) at 4% ABV
a single measure of spirit (25ml), such as whisky, gin, rum or vodka, at 40% ABV
just under half a standard glass of wine (76ml) at 13% ABV

You can find out how many units there are in different types and brands of drinks with the Drinkaware unit and calorie calculator.

If you have an Android smartphone, iPhone, iPad or iPod touch, you can download the free One You Drinks Tracker from Google Play or the iTunes App Store. It allows you to keep a drinks diary and get feedback on your drinking.

Alcohol and Pregnancy Questions and Answers

Q. What is a “drink”? What if I drink only beer or hard seltzer?

A: Any type of alcohol use can affect your baby’s growth and development and cause FASDs. This includes all wines, beer, and mixed drinks. A standard drink is defined as .60 ounces of pure alcohol. This is equivalent to one 12-ounce beer or wine cooler, one 5-ounce glass of wine, or 1.5 ounces of 80 proof distilled spirits (hard liquor). Some drinks, like mixed alcoholic drinks or malt liquor drinks, might have more alcohol in them than a 12-ounce beer. There is no safe kind of alcohol. If you have any questions about your alcohol use and its risks to your health, talk to your health care provider. You can also visit CDC’s website on alcohol.

Q: Is it okay to drink a little or at certain times during pregnancy?

A: There is no known safe amount of alcohol use during your pregnancy or when you are trying to get pregnant. There is also no safe time for alcohol use during pregnancy. Alcohol can cause problems for your baby throughout your pregnancy, including before you know you are pregnant.

FASDs are preventable if a baby is not exposed to alcohol before birth.

Q: I drank wine during my last pregnancy and my baby turned out fine. Why shouldn’t I drink again during this pregnancy?

A: Every pregnancy is different. Alcohol use during pregnancy might affect one baby more than another. You could have one child who is born healthy and another child who is born with problems.

Q: If I drank when I was pregnant, does that mean my baby will have an FASD?

A: If you used any amount of alcohol while you were pregnant, talk with your child’s healthcare provider as soon as possible and share your concerns.

You may not know right away if your child has been affected. FASDs include a range of physical and intellectual disabilities that are not always easy to identify when a child is a newborn. Some of these effects may not be known until your child is in school.

There is no cure for FASDs. However, identifying and intervening with children with these conditions as early as possible can help them to reach their full potential.

Q: Is it okay to drink alcohol if I am trying to get pregnant?

A: You might be pregnant and not know it yet. You probably won’t know you are pregnant for up to 4 to 6 weeks. This means you might be exposing your baby to alcohol without meaning to.

Alcohol use during pregnancy can also lead to miscarriage and stillbirth.

The best advice is to avoid any alcohol use when you start trying to get pregnant.

Q: If a woman has an FASD, but does not drink during pregnancy, can her child have an FASD? Are FASDs hereditary?

A: FASDs are not genetic or hereditary. If a baby is exposed to alcohol during pregnancy, the baby can be born with an FASD. But if a woman has an FASD, her own child cannot have an FASD, unless she uses alcohol during pregnancy.

Q: Can a father’s drinking cause harm to the baby?

A: How alcohol affects the male sperm is currently being studied. Whatever the effects are found to be, they are not fetal alcohol spectrum disorders (FASDs). FASDs are caused specifically when a baby is exposed to alcohol during pregnancy.

However, the father’s role is important. He can help the woman avoid alcohol use during pregnancy. He can encourage her to abstain from alcohol by avoiding social situations that involve drinking. He can also help her by avoiding alcohol himself.

Q: I suspect my child might have an FASD. What should I do?

A: If you think your child might have an FASD, talk to your child’s doctor and share your concerns. Don’t wait!

If you or the doctor thinks there could be a problem, ask the doctor for a referral to a specialist (someone who knows about FASDs), such as a developmental pediatrician, child psychologist, or clinical geneticist. In some cities, there are clinics whose staffs have special training in diagnosing and treating children with FASDs. To find doctors and clinics in your area visit the National and State Resource Directory from FASD United (formerly NOFAS).

At the same time as you ask the doctor for a referral to a specialist, call your state or territory’s early intervention program to request a free evaluation to find out if your child can get services to help. This is sometimes called a Child Find evaluation. You do not need to wait for a doctor’s referral or a medical diagnosis to make this call.

Where to call for a free evaluation from the state depends on your child’s age:

If your child is younger than 3 years old, Call your state or territory’s early intervention program and say: “I have concerns about my child’s development and I would like to have my child evaluated to find out if he/she is eligible for early intervention services. ”

If your child is 3 years old or older, contact your local public school system.
Even if your child is not old enough for kindergarten or enrolled in a public school, call your local elementary school or board of education and ask to speak with someone who can help you have your child evaluated.

ALCOHOL AND PREGNANCY - Outpatient medical facility

The fact that you can not drink alcohol during pregnancy is known to most. However, different situations can arise in life: one woman is planning a pregnancy, continuing to drink alcohol on holidays in order to avoid uncomfortable questions; another drinks a glass of wine, unaware that she is already pregnant; the third during pregnancy cannot cope with the desire to drink beer, believing that "a little bit is possible." Let's look at these situations in more detail. nine0003

Alcohol consumption during pregnancy planning.

Alcohol is a toxin that adversely affects the human reproductive system. In women, alcohol consumption leads to disruption of the menstrual cycle and hormonal balance, which significantly affects the ability to conceive. There are also opinions that even episodic alcohol consumption can have a negative effect on the eggs, leading to their inferiority. Also, alcohol consumption affects the male reproductive system, significantly reducing the number of sperm capable of fertilization. Therefore, a couple planning a pregnancy should stop drinking alcohol at least 3 months in advance in order to increase the likelihood of conception. nine0003

Drinking alcohol in the first weeks after conception.

Without a special examination, a woman usually discovers the fact of pregnancy at 3 weeks after conception, when the next menstruation does not come. By this time, the embryo has already firmly attached to the uterine cavity and began to receive nutrition from the mother's blood. If negative factors, including alcohol, affect him before the moment of attachment, then this will lead to his rejection and death, and he will simply leave the uterus with the next menstruation. Thus, a woman may not know that she was pregnant. nine0003

According to most scientists, if alcohol did not disrupt the attachment process and the embryo continued to develop, then this would not lead to the formation of malformations in it. Thus, alcohol accidentally drunk during the first two weeks after conception will either lead to the termination of pregnancy or will not affect its further development.

Alcohol use in early pregnancy.

As mentioned above, as early as the 3rd week after conception, the embryo begins to come into contact with maternal blood. This means that all the substances in the mother's blood come to him. including ethyl alcohol. From the 3rd to the 13th week of development, the laying of all the main systems of the body of the unborn child occurs and the effect of alcohol no longer leads to rejection and death of the embryo, but to the formation of malformations and deformities of the nervous, cardiovascular, and digestive systems. nine0003

Alcohol use in late pregnancy.

The negative impact of alcohol on the course of pregnancy is observed after the 13th week. Ethanol and its decay products lead to spasm of the vessels of the placenta and umbilical cord, impairing the delivery of oxygen and nutrients, leading to a delay in the development of the fetus, disruption of its nervous system and brain. A prolonged lack of oxygen can even lead to the death of a child. Violation of the nervous system in the prenatal period leads to problems in the later life of the child - such children have reduced stress resistance, problems in learning, in communication, a tendency to mental illness and alcohol consumption. nine0003

The systematic use of alcohol during pregnancy leads to the formation of fetal alcohol syndrome in a child - this is a complex of physical, mental and intellectual abnormalities in a child that cannot be treated.

Thus, alcohol and pregnancy are not compatible and it is necessary to refuse it at the planning stage.

You need to understand that one glass of wine, drunk before 2 or after 13 weeks of pregnancy, most likely will not lead to disastrous consequences, but is it worth the risk? Remember that your child will “drink” half of this glass. nine0003

What happens to the child if the mother drinks alcohol?

03.12.2019

Alcohol and pregnancy are incompatible - doctors do not get tired of talking about this to expectant mothers. But pregnant women sometimes allow themselves to skip a glass of wine, thinking that nothing bad will come of such an amount. However, alcohol can interfere with fetal development at any stage of pregnancy, even very early.

Studies show that excessive (four or more drinks at a time) and/or regular drinking by an expectant mother puts the fetus at the greatest risk of serious problems. But even a smaller amount of alcohol can be harmful, since there is no safe dose. nine0003

Alcohol easily passes from the mother's bloodstream into the child's bloodstream, which can affect the development of the brain and other vital organs, structures and physiological systems of the baby's body, leading to malformations that can begin in a child in early childhood and last a lifetime. The most profound effects of prenatal alcohol exposure are brain damage and associated behavioral and cognitive impairment.

Scientists define a wide range of effects and symptoms caused by prenatal alcohol exposure, termed "fetal alcohol spectrum disorders". These include conditions such as intrauterine alcohol syndrome, alcohol-related nervous system disorder, and alcohol-associated birth defects. All these cases have one common feature - damage to the central nervous system (CNS) as a result of prenatal alcohol exposure to the fetus. nine0003

The effect of alcohol on the CNS may be structural (eg, reduction in brain size, changes in certain areas of the brain) or functional (eg, cognitive and behavioral deficits, motor and coordination problems). Extended studies using modern imaging techniques (MRI, CT, etc.) have revealed differences in the structure and activity of the brain that are consistent with neuropsychological testing data, including a disorder in processing information from the senses, changes in cognitive processes and behavior in adults with the disorder alcohol spectrum of the fetus compared to healthy people. nine0003

The most profound effects of prenatal alcohol exposure are brain damage and associated impairments in behavioral and cognitive functioning.

How are the disorders different?

Fetal alcohol syndrome was the first form of alcohol spectrum disorder and is still the most well-known syndrome. It manifests itself with excessive alcohol consumption by the expectant mother during the first trimester of pregnancy. The impact of harmful substances on the fetus can disrupt the normal development of not only the brain, but also the face. Thus, in addition to CNS developmental anomalies, the child will have a specific pattern of three facial anomalies: narrow eye openings, a smooth area between the lip and nose (compared to a normal ridge), and a thin upper lip. Also, the baby may experience growth deficiency in utero and (or) after birth. nine0003

Partial fetal alcohol syndrome includes only some of the characteristics listed above.

An alcohol-related disorder of the nervous system is characterized by disorders of the central nervous system, which may be structural or functional. Functional impairments include a complex pattern of cognitive (mental) or behavioral problems that do not correspond to the standard level of development at any given age in a child. At the same time, the reasons for this discrepancy cannot be explained by factors other than prenatal alcohol exposure. Facial abnormalities and growth retardation should not be present. nine0003

Alcohol-related birth defects include heart, kidney, bone, and other malformations; difficulties with vision and hearing; decreased function of the immune system. They are rarely considered separately, but rather are a secondary disorder that accompanies other fetal alcohol spectrum disorders.

What will happen to the baby in the future?

Every person whose mother may have abused alcohol during pregnancy experiences a combination of everyday turmoil that includes medical, behavioral, educational, or social problems in the following areas: nine0003

learning and memorization;
understanding and following directions;
ability to hold attention;
the ability to control emotions;
communication and socialization;
performing daily life skills (eg, eating, bathing, counting money, taking care of personal safety).

People with fetal alcohol spectrum disorder are more likely than others to make bad decisions, repeat the same mistakes, trust the wrong people, and have difficulty understanding the consequences of their actions. They are also more prone to disorders such as attention deficit hyperactivity disorder, depression, impulse control problems, alcoholism and drug addiction. nine0003

People with fetal alcohol spectrum disorder are more likely than others to make bad decisions, repeat the same mistakes, trust the wrong people, and have difficulty understanding the consequences of their actions.

Risk factors

Of course, it is impossible to argue that just one sip of champagne during pregnancy can provoke many anomalies in the development of the fetus and affect the psyche of the unborn child. But the medical community recommends completely avoiding any dose of alcohol during pregnancy. nine0003

There are risk factors that contribute to the development of undesirable consequences:

amount of alcohol a pregnant woman drinks at a time;
frequency of drinking by a pregnant woman;
the stage of pregnancy at which a woman drinks alcohol, and how much she drinks during the formation of one or another body system in the fetus.

Prenatal alcohol exposure to children can be exacerbated if their mothers are malnourished, overweight, underweight, or smoke…
In addition, studies show that prenatal alcohol exposure affects children more if their mothers live in unfavorable conditions and experience high levels of stress. These may include, for example, social isolation, living in a society where excessive drinking is common and acceptable, and living in a society where resources for prenatal care are limited.

The prenatal effects of alcohol on children can be exacerbated if their mothers are malnourished, overweight, underweight, smoke… nine0003

How to help a child?

First aid for a child is the refusal of the expectant mother from alcohol. But if during pregnancy a woman allowed herself to drink alcohol and the child has symptoms of a fetal alcohol spectrum disorder, special tactics of education and training should be applied.
