Alcohol And Pregnancy

Overview

Drinking alcohol while pregnant can harm an unborn baby. Alcohol passes from the mother’s blood through the placenta to the baby, and can cause a range of problems known as fetal alcohol spectrum disorders (FASD). These can affect the baby’s brain, body, and behaviour for life.

It is not rare. Many people drink alcohol before finding out they are pregnant. FASD is considered a leading preventable cause of birth defects and developmental disabilities in many parts of the world.

It affects unborn babies whose mothers drink alcohol during pregnancy. It can also affect people planning a pregnancy, because alcohol can reduce fertility. FASD is life-long and affects children and adults of all backgrounds.

Symptoms

Common symptoms

• Problems with growth – being smaller than expected for their age.
• Difficulties with thinking, memory, and judgment.
• Behavioural issues such as hyperactivity or trouble controlling impulses.

Symptoms in children

• Distinctive facial features, such as a smooth area between the nose and upper lip.
• Poor coordination and fine motor skills.
• Trouble with learning, paying attention, or communicating.
• Social and emotional problems, like difficulty making friends or managing anger.

Symptoms in older adults

• Ongoing cognitive challenges that may need support with everyday tasks.
• Higher chance of mental health conditions such as depression or anxiety.
• Difficulty keeping a job or managing money.
• Trouble with relationships and independent living.

Causes

Main causes

• Drinking alcohol at any time during pregnancy.
• Binge drinking – having several drinks in a short time – is especially harmful.
• Alcohol can harm the baby even before a woman realises she is pregnant.

Risk factors

• No amount of alcohol has been proven safe during pregnancy.
• Having a history of alcohol use disorder or difficulty controlling drinking.
• Lack of awareness about the risks of drinking during pregnancy.
• Social or cultural pressure to drink.

When to see a doctor

See a doctor urgently if:

• If you have drunk alcohol while pregnant and feel sick, have severe abdominal pain, or notice unusual bleeding, seek medical advice the same day.
• If you are drinking heavily and find it hard to stop, ask for urgent help from your doctor or a local addiction service.

Book a routine appointment if:

• At your first pregnancy appointment, be honest about your drinking history so you can get the right support.
• If you are planning a pregnancy, talk to your doctor about your alcohol use.
• If you have already been drinking in this pregnancy, talk to a healthcare professional. It is never too late to reduce further risk.

Diagnosis

Fetal alcohol spectrum disorder is diagnosed by a team of specialists. They look at the child’s physical features, growth, brain development, and behaviour, and also consider the mother’s history of alcohol use during pregnancy.

Tests that may be done

• Physical examination to check for features of FASD.
• Assessment of growth, weight, and head size.
• Developmental and behavioural questionnaires.
• Hearing and vision tests.
• Psychological or educational assessments.

What to expect at your appointment

The doctor will ask you about your alcohol use during pregnancy in a private and non-judgmental way. For an older child, diagnosis may involve several appointments with different specialists. An early diagnosis can help you find the right support and services for your child.

Treatment

There is no cure for FASD, and it lasts a lifetime. But with early diagnosis and the right support, many children and adults can learn to manage their challenges and live well. Treatment focuses on helping with learning, behaviour, physical health, and emotional support.

Self-care at home

• Stop drinking alcohol as soon as you know you are pregnant.
• Attend all prenatal appointments and tell your midwife about your concerns.
• Avoid alcohol while breastfeeding to prevent passing alcohol to your baby.
• Seek support from friends, family, or support groups to stay alcohol-free.

Medical treatments

Medical care is tailored to the individual’s needs. It may include referral to psychologists, speech therapists, occupational therapists, and educational support services. Behavioural therapies can help with emotional regulation and daily living skills. Medications are sometimes used to manage specific symptoms, but this is decided by a specialist and must never be started without professional advice.

When is surgery considered?

Surgery is not needed for FASD itself. Occasionally, a baby with certain birth defects related to alcohol exposure may need surgery for problems such as heart defects, but this is not a treatment for the condition itself.

Living with this condition

Living with FASD means building routines and structure. Children and adults may need extra time to learn new skills, clear instructions, and a calm environment. Help them succeed by celebrating strengths, providing consistency, and using simple language.

Lifestyle tips

• Keep regular routines at home and school.
• Use visual schedules or written reminders for daily tasks.
• Build a strong support network of family, friends, and professionals.
• For adults with FASD, focus on their strengths and provide a stable, supervised environment.

Diet and exercise

A healthy, balanced diet and regular physical activity are important for everyone. For children with FASD, staying active can help with attention and mood. For pregnant women, eating well and taking prenatal vitamins as advised by your midwife or doctor is key. Avoid alcohol completely.

Mental health and emotional wellbeing

A diagnosis of FASD can bring sadness, worry, or guilt for parents. It is normal to feel overwhelmed. For a child or adult living with FASD, mental health problems such as anxiety and depression are more common. Seeking emotional support and counselling is an important part of care.

Prevention

Yes. The only sure way to prevent FASD is to not drink any alcohol while pregnant, when trying to get pregnant, and while breastfeeding.

Vaccines

There is no vaccine to prevent the effects of alcohol on pregnancy.

Screening programmes

Alcohol screening is often done at your first prenatal visit. Ask your midwife or doctor about support programs if you need help cutting down or stopping alcohol.

Complications

If left untreated

• FASD can affect a child for life, causing learning disabilities, poor memory, trouble with everyday skills, and mental health problems.
• Children with FASD may struggle in school and in relationships.
• Adults with FASD may have difficulty living independently or keeping a job.

Long-term outlook

While FASD cannot be cured, early diagnosis and support make a profound difference. Many children and adults with FASD go on to lead happy, fulfilling lives. If you have drunk alcohol during pregnancy, speak to your doctor as soon as possible – stopping now will give your baby the best chance. Every step you take towards support is a step filled with hope.
