Key points
- A hepatologist is a physician who specialises in medical treatment of liver disease — hepatitis, fatty liver, cirrhosis and its complications.
- A gastroenterologist treats the whole digestive system, including the liver, and performs endoscopy (for example, banding of varices).
- A liver transplant and HPB surgeon operates — liver transplant, removal of liver tumours, and surgery on the bile ducts, gallbladder and pancreas.
- For cirrhosis, liver failure or a liver tumour, care is safest when delivered by a team in which hepatologists and surgeons assess the patient together.
The three kinds of liver doctor
| Hepatologist | Gastroenterologist | Liver transplant & HPB surgeon | |
|---|---|---|---|
| Training in India | Physician (MD) with super-speciality training in hepatology (DM or equivalent) | Physician (MD) with super-speciality training in gastroenterology (DM or equivalent) | Surgeon (MS) with super-speciality training in GI surgery (MCh or equivalent) plus transplant and HPB fellowship |
| Main work | Diagnosis and medical treatment of liver disease; manages patients before and after transplant | Diagnosis and treatment of the gut, liver and pancreas; endoscopy, ERCP | Liver transplant, liver resection, bile duct, gallbladder and pancreatic surgery |
| Typical tools | Blood tests, FibroScan, biopsy, medicines, antiviral therapy | Endoscopy, variceal banding, ERCP stenting, colonoscopy | Open, laparoscopic and robotic surgery |
In many Indian cities, including Kolkata, the words "liver doctor" and "liver specialist" are used loosely for all three. A "hepatologist in Kolkata" search, for example, will show gastroenterologists and surgeons as well. The distinction that matters most for a patient is simple: does this problem need medicines and monitoring, an endoscopy, or an operation?
Which specialist do you need?
| Situation | Usually start with | When a liver surgeon is needed |
|---|---|---|
| Fatty liver found on ultrasound, normal or mildly raised enzymes | Your physician or a hepatologist/gastroenterologist | Rarely — only if it has progressed to advanced cirrhosis |
| Hepatitis B or C | Hepatologist or gastroenterologist for antiviral treatment | If cirrhosis becomes decompensated or a liver cancer develops |
| Cirrhosis — stable | Hepatologist for monitoring and cancer surveillance | Early referral for transplant assessment once MELD rises or complications begin |
| Cirrhosis with ascites, jaundice, confusion or bleeding | Hepatologist/gastroenterologist urgently | Transplant team assessment — see liver transplant evaluation |
| Liver tumour, including HCC | Liver/HPB surgeon and hepatologist together | Surgery or transplant may be curative — see liver cancer surgery |
| Gallstones, bile duct blockage, pancreatic mass | Gastroenterologist (ERCP) and HPB surgeon | For removal of tumours or complex bile duct surgery — see HPB surgery |
| Acute liver failure | Emergency hospital with a liver transplant unit | Immediately, in case urgent transplant is needed |
Do not wait for an outpatient appointment if there is:
vomiting blood or black stools; confusion, drowsiness or unusual behaviour; yellow eyes with high fever and shivering; a rapidly swelling abdomen; or yellowing of the eyes that appeared within days in a previously well person. Go to the nearest hospital emergency department.
How hepatologists and liver surgeons work together
Liver transplant and complex liver cancer care are team medicine. Before a transplant, hepatologists optimise the patient's condition — controlling fluid, infection, bleeding risk and nutrition — while the surgical team assesses the anatomy, the donor and the operation. After a transplant, both teams share follow-up: surgeons watch for vascular and bile duct problems, hepatologists manage immunosuppression, recurrence of the original disease and long-term health.
- 1
Referral
A patient is referred by their physician, gastroenterologist or hepatologist — or comes directly, often with reports sent on WhatsApp.
- 2
Joint review
The case is discussed by the transplant team: hepatology, surgery, radiology, anaesthesia and intensive care, and for cancers, oncology.
- 3
One plan
The family receives a single recommendation — continue medical treatment, have an operation, or begin transplant evaluation — rather than conflicting advice.
- 4
Shared follow-up
Patients living outside Kolkata usually continue with their local doctor, who stays in touch with the transplant team.
Where Dr Bappaditya Har fits in
Dr Bappaditya Har is a liver transplant and HPB surgeon, not a hepatologist. His training is surgical: MS in General Surgery (Gold Medal) at IPGMER & SSKM, MCh in GI Surgery at SGPGIMS Lucknow, and a fellowship in liver transplant and HPB surgery at Max Hospital, Delhi. He practises at Narayana RN Tagore Hospital, Mukundapur, Kolkata, where he works within a multidisciplinary transplant team that includes hepatologists, transplant anaesthetists, intensivists and transplant coordinators.
Patients typically see him when they may need an operation: liver transplant for end-stage liver failure, surgery for liver, bile duct, gallbladder or pancreatic tumours, or complex HPB and portal hypertension surgery. If your problem is better managed with medicines, he will say so and ensure you are seen by the hepatology team.
Preparing for your first visit to a liver specialist
- All blood reports, especially liver function tests, INR, creatinine, sodium and viral markers, arranged by date.
- Scan films or CDs and written reports: ultrasound, CT, MRI, FibroScan, endoscopy.
- Discharge summaries from any hospital admission.
- A list of every medicine, including herbal and indigenous remedies.
- An honest history of alcohol use — it changes the diagnosis and the plan, and it is kept confidential.
Families from West Bengal, Bihar, Jharkhand, Odisha, Assam, the North-East and Bangladesh can send these reports on WhatsApp (+91 70420 39420) before travelling, so the first visit to Kolkata is used well. For appointments, call 080675 06860. If you are unsure whether your symptoms point to liver disease at all, start with symptoms of liver disease.
Frequently asked questions
Is a hepatologist the same as a gastroenterologist?
Not exactly. Both are physicians. A gastroenterologist treats the whole digestive system, including the liver, and performs endoscopy. A hepatologist focuses specifically on the liver. In practice their work overlaps a great deal.
Is Dr Bappaditya Har a hepatologist?
No. He is a liver transplant and HPB surgeon. He works alongside hepatologists within the transplant team at Narayana RN Tagore Hospital, Kolkata.
Should I see a liver specialist for fatty liver?
Most people with simple fatty liver can be managed by their physician with weight loss, exercise and control of diabetes and cholesterol. A hepatologist or gastroenterologist is useful if enzymes stay high, a FibroScan shows scarring, or there are signs of cirrhosis.
When should a patient with cirrhosis see a liver transplant surgeon?
Earlier than most families think — when the MELD score begins to rise, or at the first complication such as ascites, jaundice, confusion or bleeding, or if a liver tumour is found. Early assessment keeps more options open.
Do I need a referral to see a liver transplant surgeon in Kolkata?
No formal referral is needed, but reports from your current doctor help. You can send them on WhatsApp before booking.
