Liver Health Professionals & Experts

A hepatologist is a medical doctor who specializes in diagnosing and treating diseases of the liver, including fatty liver disease (MASLD/MASH), hepatitis, cirrhosis, and liver failure. They provide advanced management for chronic and complex liver conditions.

Hepatologists complete extensive medical training followed by specialized fellowship education and are often board-certified in gastroenterology or internal medicine with additional expertise in liver diseases. Patients are typically referred to a hepatologist when liver disease becomes persistent, advanced, or requires specialized long-term care.

A gastroenterologist is a physician who focuses on diseases of the digestive system, including the liver, stomach, intestines, and pancreas. They commonly diagnose and manage early to moderate liver conditions such as fatty liver disease and viral hepatitis and often play a key role in initial evaluation and ongoing monitoring.

Gastroenterologists complete medical training followed by specialized fellowship training in gastroenterology and are usually board-certified in internal medicine and gastroenterology. Patients are often referred to a gastroenterologist when liver-related symptoms or abnormal liver tests require further evaluation.

An endocrinologist is a specialist who treats hormonal and metabolic disorders that can contribute to liver disease, including diabetes, obesity, and insulin resistance. They play an important role in managing metabolic dysfunction–associated steatotic liver disease (MASLD) and metabolic dysfunction–associated steatohepatitis (MASH).

Endocrinologists complete medical training followed by specialized fellowship education in endocrinology and are typically board-certified in internal medicine and endocrinology. They are often involved when liver disease is linked to metabolic or hormonal imbalances.

A liver transplant specialist is a highly trained surgeon or transplant physician who evaluates patients for liver transplantation and performs the surgical procedure when the liver can no longer function adequately. They manage patients with end-stage liver disease, acute liver failure, or certain liver cancers.

These specialists undergo extensive surgical or medical training followed by dedicated transplant fellowship programs. Patients are referred to transplant specialists when liver disease progresses to a stage where transplantation becomes the most effective treatment option.

A nutritionist is a healthcare professional who supports patients in managing liver disease through diet and lifestyle modifications. They help develop personalized nutrition plans aimed at reducing liver fat, improving metabolic health, and preventing disease progression.

Nutritionists may have formal training in dietetics or clinical nutrition depending on regional certification standards. They are commonly involved in the long-term management of conditions such as fatty liver disease and obesity-related liver disorders.

Patient support groups provide emotional, educational, and social support for individuals living with liver disease and their families. They help patients share experiences, improve coping strategies, and stay informed about disease management and lifestyle changes.

These groups are often community-based or organized through healthcare organizations and play an important role in improving quality of life for individuals managing chronic liver conditions.

A certified medical examiner is a licensed healthcare professional who is certified to perform specific medical examinations under federal requirements, most commonly the physical examinations that commercial drivers must pass to keep their medical certificate.

Certified medical examiners complete required training and pass a certification exam, and are listed on the National Registry of Certified Medical Examiners. People with a liver condition may see one when a work-related medical examination is required, for example to confirm that a condition or its treatment is stable and does not affect safe driving.

Liver advocates are people and organizations who work to improve the lives of those affected by liver disease. They raise awareness, help patients understand their rights and options, and speak up for better screening, access to care, and research funding.

Many advocates are patients, caregivers, or nonprofit staff rather than clinicians. They can help you find reliable information, navigate insurance and appointment barriers, and connect with support groups and patient programs.

Liver scientists and researchers study how liver disease develops, how it can be detected earlier, and how it can be treated. Their work ranges from laboratory research into liver biology to clinical trials that test new medications, diagnostic tests, and care approaches.

Researchers typically hold a PhD, an MD, or both, and work at universities, hospitals, research institutes, and pharmaceutical companies. Patients may meet them when taking part in a clinical study, and their findings shape the guidelines that liver specialists follow.
