Understanding what causes a baby to born with a liver problem is crucial for early diagnosis and prevention. The liver plays a crucial role in the body by carrying out important functions such as detoxifying harmful substances, producing necessary proteins, and assisting in digestion.
Medical research continues to explore what causes a baby to born with a liver problem to improve treatment outcomes. When a newborn has liver issues, it can be a major worry for both parents and medical professionals. Liver abnormalities can result from diverse causes such as genetic conditions or infections, and can result in serious complications if not detected and treated promptly.
Remember, Prenatal care plays a vital role in identifying what causes a baby to born with a liver problem early on. This blog post provides a detailed overview of liver defects in babies, covering the causes, symptoms, complications, and treatment options of liver issues in newborns.
Causes of Liver Problems in Babies
Genetic and environmental factors are key considerations in what causes a baby to born with a liver problem. Babies may have liver issues at birth for several different reasons. A few of the most frequent triggers consist of:
- Genetic disorders
- Infections during pregnancy (e.g., hepatitis)
- Biliary atresia
- Metabolic diseases
- Maternal drug or alcohol use
- Intrauterine growth restriction (IUGR)
- Prematurity Congenital structural abnormalities
- Neonatal hemochromatosis
- Immune-mediated conditions (e.g., neonatal lupus)
- Biliary (choledochal) cyst
- Alagille syndrome
1: Genetic disorders
Genetic disorders are a leading factor in the development of liver issues in newborns. These conditions result from alterations in particular genes that regulate the liver’s function or growth. An example is Alagille syndrome, a genetic condition resulting from mutations in the JAG1 or NOTCH2 genes, which cause abnormalities in bile ducts and other organs.
These mutations may be passed down from one or both parents or arise spontaneously. Genetic conditions could interfere with the typical growth and operation of the liver, leading to conditions such as chronic liver disease or other associated issues.
2: Infection during Pregnancy
Infections acquired by the mother during pregnancy, such as hepatitis B or C, can greatly affect the developing fetus. These infections may be passed on to the baby during pregnancy or delivery, causing liver inflammation and harm.
Additional maternal infections, like cytomegalovirus (CMV) or rubella, can pass through the placenta and impact the fetal liver, possibly causing serious liver ailments or even liver failure.
3: Biliary atresia
Biliary atresia is a severe condition present at birth, characterized by the absence, blockage, or malformation of the bile ducts within or outside the liver. This blockage stops the flow of bile from leaving the liver, causing a buildup of bile which then damages the liver.
If surgical intervention is not done promptly, biliary atresia can lead to cirrhosis, liver failure, and the necessity of a liver transplant. The precise reason behind biliary atresia is not completely known, but it is thought to be influenced by a mix of genetic predisposition and environmental factors.
4: Metabolic diseases
Inherited metabolic disorders refer to a collection of genetic conditions in which the baby’s system fails to metabolize specific substances efficiently, resulting in the buildup of toxic compounds in the liver. An instance of glycogen storage diseases occur when enzyme deficiencies interfere with glycogen metabolism, leading to liver enlargement and dysfunction.
In the same way, disorders such as galactosemia result in the body’s inability to process specific sugars, leading to harm to the liver. These conditions frequently need ongoing care and can have a major effect on a child’s health if not caught early. (Also read, What are healthy breakfast meals for a baby)
5: Maternal drug or alcohol use
Drug or alcohol consumption by the mother while pregnant can result in severe harm to the developing liver. Alcohol, specifically, can result in fetal alcohol syndrome (FAS), which is known for causing liver damage, growth issues, and delays in development.
Medications, both prescription and illicit, as well as over-the-counter remedies, can pass through the placenta and cause damage to the baby’s liver, resulting in conditions like neonatal hepatitis. The extent of liver injury is determined by the kind and quantity of substance consumed, along with the timing in pregnancy.
6: Intrauterine growth restriction (IUGR)
Intrauterine growth restriction (IUGR) is the result of a baby not achieving the expected growth in the womb because of factors such as placental insufficiency, maternal malnutrition, or chronic health issues.
IUGR may lead to organs, such as the liver, being underdeveloped, which could increase the baby’s risk of liver issues post-birth. These infants may experience impaired liver function and are more susceptible to metabolic disorders and additional complications.
7: Prematurity
Being born prematurely is also a major factor that increases the risk of liver issues in newborns. Prematurely born babies may have incomplete organs, such as the liver, that may not be able to fully carry out critical functions like processing bilirubin.
This may result in ailments like neonatal jaundice, in which the baby’s liver struggles to effectively metabolize and eliminate bilirubin, resulting in a yellowing of the skin and eyes. Premature babies are also more likely to experience infections and metabolic imbalances, potentially leading to further issues with liver function.
8: Congenital structural abnormalities
Congenital structural abnormalities are defects in the liver or bile ducts that are present from birth. Conditions such as biliary atresia or choledochal cysts can cause abnormalities that block the regular bile flow, resulting in liver damage.
Genetic factors, environmental exposures, or a combination of both can lead to structural abnormalities. Early detection and surgical intervention are frequently required to avert enduring liver harm and guarantee optimal liver performance.
9: Neonatal Hemochromatosis
Neonatal hemochromatosis is an uncommon and frequently lethal illness characterized by an excessive buildup of iron in the liver and other body parts. It is believed that this condition results from maternal alloimmune disease, in which the mother’s immune system targets the fetal liver, resulting in excess iron.
An abundance of iron results in serious liver harm, often resulting in liver failure. Failure to receive immediate treatment, such as intensive chelation therapy or a liver transplant, can pose a serious risk to the life of a newborn with hemochromatosis.
10: Immune-Mediated Conditions
Conditions caused by the immune system, like neonatal lupus, happen when antibodies from the mother cross the placenta and target the baby’s liver. During neonatal lupus, the baby’s tissues are attacked by maternal autoantibodies, causing inflammation and harm in the liver and other organs. This disease is uncommon but can cause serious liver problems, necessitating close supervision and treatment.
11: Biliary (Choledochal) Cysts
Congenital malformations of the bile ducts, known as biliary (choledochal) cysts, can block the flow of bile, resulting in the buildup of bile and damage to the liver. If left untreated, these cysts may lead to issues like cholangitis, pancreatitis, or even bile duct cancer, with variations in size and location.
12: Alagile Syndrome
Alagille syndrome is a complicated genetic condition that impacts various organs such as the liver, heart, and kidneys. Mutations in the JAG1 or NOTCH2 genes, essential for bile duct development, are responsible for the condition.
Alagille syndrome is characterized by the narrowing or reduced number of bile ducts, resulting in the build-up of bile, liver damage, and the development of chronic liver disease. This disorder is passed down in an autosomal dominant manner, resulting in a 50% likelihood of a child inheriting it if one parent has the mutated gene.

Symptoms of Liver Defects in Babies
Different symptoms may appear in newborns with liver abnormalities, depending on the root cause. Common signs often include jaundice (yellowing of the skin and eyes), which happens when bilirubin levels rise in the bloodstream due to poor liver performance. Infants can also have dark urine and light-colored stools, which could suggest an issue with the flow of bile.
Enlargement of the stomach, inadequate weight increase, and delays in growth are additional symptoms of liver malfunction. In some instances, babies might struggle with feeding, vomit, or show signs of irritability because of discomfort. Liver failure can happen in extreme situations, resulting in complications that could be life-threatening.
Complications of Liver Defects
Failure to promptly diagnose and treat liver defects in babies can result in serious complications. Some of the issues involved are cirrhosis, which occurs when the liver is damaged and can no longer work effectively. Portal hypertension can also result in abdominal and esophageal swelling by increasing the blood pressure in the liver’s blood vessels.
Liver failure is a serious issue that can result in death if not treated with a liver transplant. Infants with liver abnormalities are also vulnerable to experiencing infections, malnourishment, and delays in development because the liver cannot effectively process nutrients and remove toxins from the body.
Which Children Are at Risk?
Although, experts are investigating multiple factors to understand what causes a baby to born with a liver problem.But, there are some factors elevate the likelihood of a baby being born with liver issues. Infants whose relatives have genetic liver conditions like Alagille syndrome are more likely to be at risk. Infections contracted by the mother during pregnancy, like hepatitis or rubella, can also raise the chances of liver abnormalities in the baby. Infants born to mothers who consumed drugs or alcohol while pregnant face an increased likelihood of liver harm.
Premature babies and individuals with intrauterine growth restriction (IUGR) have a higher chance of having immature livers, putting them at risk for liver issues. Furthermore, infants born with congenital structural abnormalities or metabolic diseases are more likely to develop liver defects.
Diagnosis
Identifying liver issues in babies usually requires a mix of physical check-ups, blood tests, imaging scans, and occasionally genetic testing. Jaundice or unusual liver test results in a newborn might lead to additional examination. Ultrasound or MRI imaging can be utilized to identify structural irregularities such as biliary atresia or choledochal cysts.
Genetic testing can be done to verify diseases such as Alagille syndrome or metabolic disorders. Specific blood tests can detect viral or bacterial infections that could have impacted the liver in cases where infections are suspected. Liver biopsies can also be carried out to evaluate the level of liver damage and identify the root cause.

How to Take Care of Liver Affected Babies
Taking care of an infant with liver issues necessitates consistent supervision and frequent medical attention. Parents need to collaborate with a pediatric gastroenterologist or hepatologist to handle the condition effectively. Adequate nutrition is important, as babies with liver issues might struggle to metabolize specific nutrients.
When to Call a Doctor
If parents notice any symptoms of liver issues in their baby, like skin or eye yellowing, dark urine, pale stools, or abdominal swelling, they should promptly consult a doctor. Additional worrying signs include inadequate eating, throwing up, crankiness, or lack of weight gain.
In case the baby experiences a fever, lethargy, or any distress signals, immediate medical attention is required. Intervening early is essential in order to avoid complications and guarantee the best outcome for the baby.
Is There Any Natural Remedy?
Although natural remedies may seem appealing, it’s crucial to recognize that liver issues in infants are severe medical concerns that necessitate professional medical intervention. No scientifically supported natural cure exists for liver issues in infants.
Depending on natural remedies without medical guidance can postpone essential medical care and result in the deterioration of the condition. Parents should make sure to consult a healthcare provider before attempting any alternative therapies and should give priority to treatments recommended by doctors.

What Are the Possible Treatments?
The course of action for infant liver issues is determined by the root cause. Surgery is frequently needed to restore bile flow and prevent additional liver damage in cases such as biliary atresia. Dietary management and enzyme replacement therapies may be required in situations involving metabolic diseases.
If infections are responsible, antiviral or antibiotic drugs will be given to address the infection and avoid liver damage. Infants who have serious liver damage or liver failure might need to undergo a liver transplant, a complicated surgery that can ultimately save their lives. Proper nutrition and symptom management are crucial components of treatment, along with supportive care.

Precautionary Measures to Avoid Liver Defects in Babies
Scientists and medical professionals are actively researching methods to avoid liver issues in newborns, with prevention tactics varying depending on the exact reason for the liver abnormality.
There is currently no known way to completely prevent genetic disorders such as Alagille syndrome because they are inherited. Nonetheless, preconception genetic counseling can assist parents at risk in comprehending the likelihood of passing down these disorders.
Vaccines and antiviral medications administered to pregnant women with infections like hepatitis B or C can greatly decrease the chances of passing the virus to their baby. Testing for infections during prenatal appointments and providing treatment for the mother if needed are essential tactics.
Public health interventions play a crucial role in educating and supporting women to avoid harmful substances during pregnancy in cases of maternal drug or alcohol use. Initiatives that support healthy pregnancies and deter substance use are able to prevent these liver abnormalities.
There is no known way to prevent biliary atresia, but early identification and the Kasai procedure can greatly enhance results. Studies are being conducted to discover possible environmental or viral triggers to improve prevention methods.
Preventive measures for neonatal hemochromatosis primarily involve administering intravenous immunoglobulin (IVIG) therapy during at-risk pregnancies, as certain studies have indicated its ability to lower the likelihood of recurrence in future pregnancies.
Newborn screening programs have achieved success in identifying and treating metabolic diseases, helping to prevent severe liver damage. Sometimes, controlling diet from infancy can help avoid or reduce liver problems.
In general, even though there are still unknown prevention methods for certain liver defects, progress in prenatal care, vaccination, genetic counseling, and public health efforts have greatly helped in decreasing the occurrence and seriousness of liver issues in infants.
