What’s the most important thing you need to know about serious liver disease in children? It’s very rare. And, when children get liver disease, they aren’t likely to need liver transplants. But even though the condition is uncommon, spotting signs of liver disease early is important.
The liver helps clean the blood, manage blood flow, break down toxins and create bile that helps digest food. When the liver isn’t working well, it can affect a child’s energy, growth, learning and overall health.
Liver disease in children can range from mild irritation to more serious conditions like fatty liver disease, problems with the bile ducts, infections or long-term scarring. Early detection and treatment can help prevent complications such as liver cirrhosis or liver failure.
Ali Ghazi-Askar, MD, a pediatric gastroenterologist with Banner Health, explained more about liver disease in children.
Early stages: What liver problems can look like
Early liver disease may not cause clear symptoms. Children may seem tired, lose their appetite or grow more slowly. These mild signs can be easy to overlook, which is why it’s important to pay attention to changes over time.
Warning signs parents should watch for
When liver disease gets worse, you may see these symptoms in children:
- Jaundice: Yellowing of the skin or eyes is one of the most common signs of liver trouble. It happens when the liver cannot process bile pigment properly.
- Dark urine or pale stools: Changes in digestion and bile production can lead to these changes.
- Bloody stools or vomiting blood: Bleeding can happen when the liver isn’t making enough clotting factors or when pressure builds in nearby blood vessels. Get immediate medical care for bloody stools or vomiting blood.
- Swollen belly: Fluid in the abdomen may build up and make a child’s stomach appear round or tight.
- Enlarged liver or spleen: Doctors may feel or see this change during an exam. It can be a sign of inflammation, but it also can be normal because the liver gets bigger when you’re fighting illness.
- Easy bruising or bleeding: Liver problems can affect how blood clots and how red blood cells break down, so bruises can appear more often and bleeding can be heavier. “Easy bleeding is a more serious sign,” Dr. Ghazi-Askar said.
- Fatigue or weakness: Trouble processing nutrients or removing toxins can make a child feel very tired, even when they are getting enough rest.
Conditions that may lead to liver disease
Several health problems can affect a child’s liver, including:
- Fatty liver disease, which is linked with obesity and is becoming more common in children
- Viral infections like hepatitis B and C
- Autoimmune disorders
- Blocked or poorly formed bile ducts
- Genetic or metabolic conditions
Some conditions that cause liver disease in children get better with treatment. For others, children may need long-term care from a pediatric liver specialist.
When symptoms signal something more serious
Some symptoms suggest more advanced liver disease and require urgent attention:
- Severe belly swelling
- Confusion
- Extreme tiredness
- Severe vomiting or vomiting blood
- Intense, sudden pain
- Fever
- Signs of high blood pressure inside the liver, such as veins showing on the abdomen or swelling in the legs, because the liver can’t make proteins that prevent swelling
Get emergency care if your child has any of these symptoms.
How liver disease is diagnosed
Doctors perform physical exams and use several tools to understand how well a child’s liver is working:
- Blood tests: These measure liver function and check for inflammation, infection, clotting factor issues or anemia.
- Imaging tests: An ultrasound or CT scan can show swelling, blockages, damage or changes in blood flow through the liver.
- Liver biopsy: Doctors may recommend taking a sample of tissue from the liver if they need a closer look. This can help confirm conditions like liver cirrhosis or fatty liver disease and help with treatment planning.
“Basic screening for liver irritation can be done with blood work and ultrasound, without radiation. So, if parents have concerns, pediatricians can quickly evaluate it and recommend seeing a gastrointestinal physician or hepatologist if needed,” Dr. Ghazi-Askar said.
Treatment options
Treatment depends on what’s causing the liver disease. “Fatty liver disease can largely be reversed with weight loss through diet and exercise. This is the most common liver disorder I see and the only one that we can cure without medications,” Dr. Ghazi-Askar said.
Children with fatty liver don’t usually develop serious symptoms when they are young, but about 10% develop cirrhosis (liver scarring) as adults.
For other types of liver disease, treatment options may include:
- Medication for infections or inflammation
- Procedures to open blocked bile ducts
- Nutrition support to maintain liver function
- Monitoring for complications like fluid buildup or scarring
- Specialist care for advanced diseases such as liver failure
When to talk with a provider
“Talk to a doctor anytime you are concerned about fatigue, easy bruising or bleeding, skin that’s more pale or more yellow or poop that’s white,” Dr. Ghazi-Askar said.
