Reviewed by Liver Health Experts
Liver diseases are conditions that damage or impair the liver, a vital organ responsible for filtering toxins, producing proteins, storing energy, and supporting digestion. The liver performs over 500 essential functions in your body. When liver diseases develop—whether from metabolic issues, viral infections, genetic factors, alcohol use, or other causes—they can disrupt these critical processes and lead to serious complications if left untreated.
This page covers the major types of liver diseases, including metabolic, viral, genetic, alcohol-related, and cancer-associated conditions. You'll learn about common symptoms, how the liver works, prevention strategies, and when to seek specialist care. Explore detailed condition pages and connect with liver specialists near you for expert evaluation and personalized treatment.

Why Liver Health Matters
How Your Liver Works
The liver performs hundreds of essential functions that keep your body running smoothly. From filtering toxins and producing vital proteins to storing energy and supporting digestion, the liver plays a central role in metabolism, immunity, and overall health. These are the key functions that matter most for understanding how your liver supports your well-being.
Important: Early liver testing can detect damage before symptoms appear, helping you protect your liver health.
Common Liver Conditions
Metabolic liver diseases develop when the body processes fats, sugars, or nutrients improperly, leading to liver inflammation, fat buildup, or scarring. These conditions are increasingly common worldwide and are strongly linked to obesity, diabetes, insulin resistance, and lifestyle-related health risks.
Liver transplant topics:
Viral liver diseases are caused by infections that attack liver cells and may lead to chronic inflammation, fibrosis, cirrhosis, or liver failure if untreated. Early diagnosis and antiviral treatments can significantly improve liver health outcomes.
Types of viral liver diseases:
Genetic liver diseases are inherited conditions that affect liver function, metabolism, or bile flow. Many genetic disorders appear early in life, while others may remain undiagnosed until adulthood. Early screening and specialized care are critical for long-term management.
Types of genetic liver diseases:
Liver cancer develops when abnormal cells grow uncontrollably in liver tissue. Chronic liver disease, hepatitis infections, and cirrhosis are major risk factors. Early detection, imaging, and advanced treatment options improve survival and quality of life.
Types of liver cancer:
Liver comorbidities are health conditions that commonly occur alongside liver disease and may worsen liver damage or affect treatment outcomes. Managing related conditions is essential for improving overall liver wellness and patient care.
Common comorbidities:
Advanced liver disease can lead to serious complications that affect multiple organs and overall health. Recognizing warning signs early helps reduce hospitalizations and improve long-term prognosis.

Recognizing the signs
Liver disease can present with a range of symptoms. If you experience several of these, consider speaking with a specialist.
Early detection & liver health
Maintaining liver health reduces the risk of fatty liver disease (MASLD), hepatitis complications, and long-term liver damage. Prevention focuses on healthy lifestyle choices — balanced nutrition, regular exercise, healthy weight, limiting alcohol, and avoiding unnecessary medications or supplements that may harm the liver. Hepatitis A and B vaccination is recommended for at-risk individuals.
Liver disease often develops silently without early symptoms, making regular screening essential for early detection. Liver function panels (LFTs), ultrasound imaging, and FibroScan help identify fatty liver disease and fibrosis at an early, treatable stage. Screening is especially important for people with diabetes, obesity, alcohol use, or a family history of liver disease.
See a liver specialist (hepatologist) if you experience fatigue, jaundice, abdominal pain, or abnormal liver test results. People with obesity, diabetes, high cholesterol, or alcohol-related risk factors should also consider early evaluation. Early specialist care helps prevent progression to cirrhosis, liver failure, or liver cancer.
Regular screening can catch liver disease early, when treatment is most effective and damage is reversible.

Common questions
Fatty liver disease (MASLD) is the most common liver disease in the Western Hemisphere. Other common conditions include viral hepatitis, alcohol-related liver disease, genetic liver disorders, cirrhosis, and liver cancer. Many of these share risk factors such as obesity, type 2 diabetes, alcohol use, and viral infections.
Common signs include jaundice (yellow skin and eyes), fatigue and weakness, dark urine or pale stools, itchy skin, abdominal pain and swelling, nausea, easy bruising, and confusion or memory problems. Liver disease often causes no symptoms in its early stages, so many people learn about it through a routine checkup or blood test. Symptoms can appear suddenly or build slowly over time.
See a doctor if you have symptoms that worry you or think you are at risk, and ask about a hepatologist (liver specialist) if you have jaundice, ongoing fatigue, abdominal pain, or abnormal liver test results. Risk factors such as diabetes, obesity, high cholesterol, or heavy alcohol use are also good reasons to ask about an early evaluation.
Some early liver conditions can be reversed. Fatty liver disease and NASH, its inflamed form, can improve with weight loss, regular exercise, liver-healthy eating, and less alcohol. Cirrhosis, which is permanent scarring, cannot be reversed. If lifestyle changes are not kept up, fatty liver disease can keep progressing. Talk with your doctor about a treatment plan.
Fatty liver disease can move through four stages. It starts with fat buildup in the liver. Next, inflammation develops, which is called NASH. Then scarring (fibrosis) forms. In the last stage, cirrhosis, healthy liver cells are replaced by scar tissue, which can lead to liver failure. Left untreated, it also raises the risk of liver cancer.
Doctors usually combine several steps. They review your medical history, do a physical exam, and order blood tests, also called liver function tests. They may add imaging tests such as ultrasound, MRI, or CT. In some cases, a liver biopsy is needed to confirm the diagnosis. Your doctor decides which tests fit your situation.
A liver-healthy lifestyle is the best protection. Keep a healthy weight, eat a balanced diet, exercise regularly, and limit alcohol. Take only the medications and supplements your doctor recommends. Hepatitis A and B vaccination is recommended for people at risk. Regular checkups matter too, because liver disease often has no early symptoms.
