What is Liver Disease?
The liver is a vital organ that plays a crucial role in the body’s functioning. Liver disease encompasses a wide range of conditions that can affect the liver’s structure and function, leading to various health complications. These conditions may be caused by factors such as genetics, infections, autoimmune responses, toxins, or metabolic disorders. Liver disease can present in different forms, ranging from mild inflammation to severe scarring (cirrhosis) and even liver failure.
In children, liver disease can include conditions like hepatitis, fatty liver disease, and inherited disorders such as Wilson’s disease and alpha-1 antitrypsin deficiency. Hepatitis refers to inflammation of the liver, commonly caused by viruses like hepatitis A, B, or C, but can also result from excessive alcohol consumption or certain medications. Fatty liver disease involves fat accumulation within liver cells, which, if not properly managed, may lead to liver inflammation and damage.
The symptoms of liver disease in children can vary widely depending on the underlying cause and severity. Common signs include jaundice (yellowing of the skin and eyes), abdominal pain, fatigue, and nausea. If left untreated, liver disease can lead to serious complications such as cirrhosis or liver failure. Early detection and treatment are crucial for improving outcomes in children with liver disease.

Where is the Liver Located?
The liver is located in the upper right side of the abdomen, beneath the diaphragm and above the stomach. It is one of the largest organs in the human body and plays a vital role in various metabolic processes. Structurally, the liver is divided into two main lobes: the right lobe and the left lobe. The right lobe is much larger than the left and contains approximately 60% of the liver’s mass.
The liver is closely situated to several other organs, including the gallbladder, which stores bile produced by the liver, and the ascending colon, a section of the large intestine. Due to its strategic location, any inflammation or enlargement of the liver can result in discomfort or pain in the upper right abdomen. This discomfort is often one of the first signs that healthcare providers may investigate when diagnosing liver disease.
What is the Function of the Liver?
The liver serves a multitude of vital functions in the body:
- Metabolism: The liver processes nutrients absorbed from the digestive tract, converting them into usable forms for energy, growth, and repair. It also regulates blood sugar levels by storing glucose as glycogen and releasing it when needed.
- Detoxification: The liver filters toxins such as drugs, alcohol, and other harmful substances from the bloodstream. Specialized liver cells, known as hepatocytes, help break down toxins into less harmful byproducts that can be excreted through urine or bile.
- Bile Production: The liver produces bile, a fluid essential for digesting fats. Bile is stored in the gallbladder and released into the small intestine to aid in fat digestion and absorption of fat-soluble vitamins such as A, D, E, and K.
Without proper liver function, a child may experience difficulty in processing nutrients and detoxifying harmful substances, which can severely impact their overall health.

Common Liver Disease Symptoms in Children
Liver disease in children can present with a variety of symptoms. Common indicators include:
- Jaundice: Yellowing of the skin and eyes, caused by excess bilirubin in the bloodstream.
- Abdominal pain or swelling: The liver’s location in the upper right abdomen makes pain or tenderness in this area a common symptom of liver dysfunction.
- Fatigue: The liver’s crucial role in energy metabolism means that its dysfunction can result in overall weakness and fatigue in children.
- Nausea and vomiting: Digestive problems due to liver dysfunction may lead to digestive distress.
Early identification of these symptoms can help healthcare providers diagnose and manage liver disease more effectively, improving the chances of successful treatment.
Liver Disease Treatment at CHOC
At CHOC Children’s Hospital, the treatment of liver disease in children is approached with specialized care and expertise. The medical team, including pediatric hepatologists, surgeons, and dietitians, work together to create personalized treatment plans.
Medications are often prescribed to control inflammation, manage symptoms, or prevent further liver damage. If medications alone are insufficient, surgical interventions may be necessary. These can range from minimally invasive procedures to liver transplants.
Nutrition also plays a key role in managing liver disease. CHOC’s dietitians collaborate with families to develop customized nutrition plans that support optimal liver function and overall health. These plans may involve dietary restrictions, supplements, or meal plans tailored to each child’s needs.

Tests Used to Diagnose Liver Disease at CHOC
CHOC utilizes a variety of diagnostic tools to accurately assess liver function and diagnose liver disease in children:
- Blood tests: These can measure liver enzyme levels (e.g., ALT, AST) and bilirubin levels to identify liver inflammation or dysfunction.
- Imaging tests: Ultrasound and CT scans are commonly used to visualize the liver’s structure, detect abnormalities like tumors or cysts, and assess liver size.
- Liver biopsy: In some cases, a small sample of liver tissue is taken to evaluate the extent of liver damage, inflammation, or scarring.
These tests help doctors understand the severity of the liver disease and guide treatment decisions.
Conclusion
Liver disease in children is a complex condition that requires specialized care. By recognizing common symptoms early, understanding the liver’s vital functions, and seeking timely medical attention, parents and caregivers can help ensure that children with liver disease receive the best possible care.
Advancements in medical research and technology have significantly improved diagnostic tools and treatment options, offering hope for better outcomes. Through a multidisciplinary approach, healthcare providers can offer comprehensive care that addresses both the physical and emotional needs of young patients and their families.
Raising awareness, supporting ongoing research, and advocating for early screening can make a significant difference in the lives of children with liver disorders. Together, we can help children thrive despite these challenges.
