Targeting Hepatologists in the US

Hepatologists are one of the highest-value and hardest physician audiences to reach online. There are only about 7,000 to 8,000 Hepatology providers in the US, a small and highly specialized field, just as liver disease surges: fatty liver disease (MASLD and MASH) now affects roughly a third of adults, alongside viral Hepatitis, cirrhosis and rising liver cancer. Our HCP Targeting is audience-based, not Contextual, so we reach the Hepatologist as a clinician and as a person, wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content alike. That is broader reach across brand-safe, premium inventory, through Programmatic and Managed Campaigns, in the US.

HCP Targeting with USA Flag & Stethoscope

Our HCP Targeting (including this Hepatologist Targeting Segment) is available in the USA only, delivered with geo-targeting to the United States.

Need to reach HCP audiences based outside the US? It’s harder, but we’ve had success targeting them through Clinical Websites and Contextual Targeting.

The Hepatologist Audience

Hepatologists are a small and highly specialized physician audience, and many train first in Gastroenterology before subspecializing in the liver. Demand keeps climbing as fatty liver disease reaches epidemic levels and liver cancer rises. That scarcity is the point: Hepatologists sit at the center of how liver disease is diagnosed, managed and treated, from viral Hepatitis B and C, MASLD and MASH and alcohol-associated liver disease to cirrhosis, portal hypertension, autoimmune and cholestatic liver disease, hepatocellular carcinoma and liver transplant. They own some of the fastest-emerging drug relationships in medicine, from the first approved MASH therapies to Hepatitis and transplant regimens, which makes them a high-value audience for Pharmaceutical, Biotech, Diagnostics and Healthcare Technology brands. As the MASH and liver-disease pipeline expands, Hepatologists sit at the center of a high-growth market and are a high-value audience to reach at scale.

Why Advertise to Hepatologists

Hepatologists sit on top of one of the fastest-emerging drug markets in all of medicine. On the drug side they choose and manage Hepatitis C Direct-Acting Antivirals, Hepatitis B antivirals like Tenofovir and Entecavir, the first approved MASH therapy Resmetirom and a deep NASH pipeline, cholestatic liver drugs for PBC and PSC, systemic therapies for hepatocellular carcinoma, treatments for hepatic encephalopathy like Rifaximin and Lactulose, portal hypertension therapies, and transplant Immunosuppression. On the device and technology side they drive demand for liver Elastography and FibroScan, imaging, and the diagnostics used to stage fibrosis and detect liver cancer. Their influence reaches well beyond a single prescription. Hepatologists shape hospital and transplant-center formularies, sit on the committees that decide which high-cost liver therapies a system will cover, and lead the Clinical Trials driving the MASH and liver-disease pipeline. Winning the Hepatologist shapes prescribing across a small but rapidly growing market.

Take an “Always On” Strategy for Targeting Hepatologists

Finding a small audience like Hepatologists is a needle-in-a-haystack job. There are only about 7,000 to 8,000 of them in the US, stretched across a growing and aging patient population, and they’re some of the busiest people in medicine: running back-to-back Colonoscopy and Endoscopy lists, moving between the Endoscopy Suite, the clinic and the wards. You can rarely predict when one is online, whether it’s between cases, after a full procedure day or on a weekend.

That’s why we recommend an Always On strategy for an audience like this: run the campaign 24/7, 365 days a year so you reach Hepatologists whenever they surface, not just in a short burst. Continuous delivery builds reach and frequency over time, so you’re already in front of them by the time your message matters most.

An Always On budget goes further with an Omnichannel approach. Rather than betting on one screen, you reach Hepatologists across the whole day: on their phone in the staff room, through a podcast in the car, on the office desktop between patients, and on Connected TV while they unwind at home. Same audience, more moments, more chances for your message to land.

Frequently Asked Questions (FAQs)

A Hepatologist is a physician who specializes in the liver, gallbladder, bile ducts and pancreas, and the diseases that affect them. They diagnose and manage conditions like viral Hepatitis, fatty liver disease (MASLD and MASH), cirrhosis, portal hypertension, autoimmune and cholestatic liver disease, liver cancer and liver failure, and they care for patients before and after liver transplant. Most train first in Gastroenterology and then subspecialize in Hepatology.

Hepatology is a small, highly specialized field, with roughly 7,000 to 8,000 physicians and providers focusing primarily on the liver, many of them Gastroenterologists. Demand keeps rising as fatty liver disease, viral Hepatitis and liver cancer climb. That makes Hepatologists a scarce, high-value and hard-to-reach audience.

Hepatologists treat the full range of liver and biliary disease. That includes viral Hepatitis B and C, fatty liver disease (MASLD and MASH), alcohol-associated liver disease, cirrhosis and its complications like portal hypertension and hepatic encephalopathy, autoimmune Hepatitis, cholestatic diseases like PBC and PSC, hepatocellular carcinoma, and liver failure, including care before and after liver transplant.

They overlap closely. Gastroenterologists care for the entire digestive system, including the esophagus, stomach, intestines and colon, as well as the liver. Hepatologists focus specifically on the liver, gallbladder, bile ducts and pancreas, and on complex conditions like advanced cirrhosis, liver cancer and transplant. Most Hepatologists train in Gastroenterology first, then subspecialize in the liver.
