Key points
- Early liver disease — fatty liver, hepatitis B or C, early scarring — usually causes no symptoms at all.
- Late signs include jaundice, a swelling abdomen, confusion, easy bruising and vomiting blood — these mean the liver is failing.
- Three simple tests pick up most liver disease: liver function tests, an ultrasound and a FibroScan.
- People with diabetes, obesity, regular alcohol use, hepatitis B or C, or a family history of liver disease should be checked even if they feel well.
Why liver disease is often silent
The liver has a huge reserve and a remarkable ability to repair itself. It has no pain nerves inside it, so damage does not hurt. Scarring (fibrosis) builds up slowly over years from fat, alcohol or viral hepatitis while blood tests may be only mildly abnormal. By the time symptoms appear, the scarring has often reached cirrhosis.
The good news is the reverse: when liver disease is found early, removing the cause — losing weight, stopping alcohol, treating hepatitis — can halt and often partly reverse the damage. That is the case for testing people at risk rather than waiting for symptoms.
Early and non-specific signs
When early liver disease does cause symptoms, they are vague and easily blamed on work, age or diabetes:
- Tiredness and low energy that does not improve with rest.
- Loss of appetite, mild nausea and a feeling of fullness after small meals.
- Unexplained weight loss or muscle wasting, sometimes hidden by fluid or a big abdomen.
- A dull ache or heaviness in the upper right abdomen.
- Itching of the skin without a rash, often worse at night — common in bile-duct diseases.
- Reduced sex drive, irregular periods, or breast enlargement in men.
None of these alone proves liver disease, but together — especially in someone with risk factors — they justify a blood test and ultrasound.
Later signs: when the liver starts to fail
Jaundice and dark urine →
Yellow eyes and skin, tea-coloured urine, sometimes pale stools.
Swelling of the abdomen and legs →
Fluid in the abdomen (ascites) and ankle swelling from low albumin and portal hypertension.
Easy bruising and bleeding
Bruises from minor knocks, bleeding gums or nosebleeds, because the liver makes fewer clotting proteins and the spleen traps platelets.
Skin changes
Spider naevi — small red spots with thin spreading vessels on the chest, face and arms; red palms (palmar erythema).
Confusion and sleep reversal →
Forgetfulness, daytime drowsiness and flapping hands.
Vomiting blood or black stools →
Bleeding from swollen veins in the food pipe.
Doctors call the appearance of jaundice, ascites, encephalopathy or variceal bleeding decompensation. It marks the point at which the liver can no longer cope, and it is the usual trigger for a liver transplant evaluation.
Symptoms that need hospital care today
Go to hospital the same day for:
vomiting blood or passing black, tarry stools; confusion, unusual sleepiness or difficulty waking; new jaundice with drowsiness or bleeding; fever or abdominal pain in someone with fluid in the abdomen; passing very little urine; or a fast-swelling abdomen with breathlessness. These can signal bleeding varices, infection, kidney failure or acute liver failure.
Sudden deterioration in someone with known cirrhosis — after an infection, a drinking binge or a bleed — may be acute-on-chronic liver failure, which needs intensive care and early contact with a transplant centre.
Simple tests that find liver disease
| Test | What it shows | Limitations |
|---|---|---|
| Liver function tests (LFT) | Bilirubin, enzymes (ALT, AST, ALP, GGT), albumin; often done with INR and platelet count | Can be normal even in cirrhosis; enzymes show injury, not how much scarring |
| Ultrasound of the abdomen | Fatty liver, a shrunken or irregular liver, spleen size, fluid, gallstones, lumps | Early scarring can be missed |
| FibroScan (transient elastography) | Liver stiffness — an estimate of how much scarring there is — and a fat score | Less accurate with severe obesity, recent meals or active hepatitis |
| Hepatitis B and C tests | HBsAg and anti-HCV antibody — both treatable infections | A positive result needs further tests to measure the virus |
Simple scores such as FIB-4, calculated from age, AST, ALT and platelet count, help decide who needs a FibroScan. When a lump is seen, a contrast CT or MRI is used to check for liver cancer.
Who should get their liver checked
- Type 2 diabetes or obesity, especially abdominal fat — the main drivers of fatty liver disease, now very common in Indian cities.
- Regular alcohol use, even if it feels moderate; see alcohol-related liver disease.
- Hepatitis B or C, or a family member with either; past blood transfusions, dialysis, or unsafe injections — see hepatitis B and C.
- Family history of cirrhosis or liver cancer, or of genetic conditions such as Wilson's disease or haemochromatosis.
- Long-term use of certain medicines, herbal or indigenous remedies, or bodybuilding supplements.
- Abnormal liver tests found by chance on a health check — these deserve a proper explanation, not repeated tests alone.
Who to see and what happens next
Most liver problems are first managed by a physician, gastroenterologist or hepatologist — see which liver specialist you need. A liver transplant and HPB surgeon becomes involved when there is decompensated cirrhosis, liver failure, a liver tumour, or a blocked bile duct from a mass.
Dr Bappaditya Har sees such patients at Narayana RN Tagore Hospital, Mukundapur, Kolkata. Families elsewhere in eastern India or Bangladesh can send reports on WhatsApp (+91 70420 39420) before deciding whether to travel. Appointments: 080675 06860.
Frequently asked questions
What are the first signs of liver damage?
Often there are none. When present, early signs are vague: tiredness, poor appetite, mild nausea and discomfort under the right ribs. Abnormal liver tests or a fatty liver on ultrasound are frequently the first clue.
Can liver tests be normal in cirrhosis?
Yes. Liver enzymes can be normal in established cirrhosis. A low platelet count, low albumin, a raised INR, an irregular liver on ultrasound or a high FibroScan reading may be the only signs.
Is itching a sign of liver disease?
It can be, particularly in conditions that affect bile flow such as primary biliary cholangitis, bile duct blockage or pregnancy-related cholestasis. Itching without a rash that persists deserves a liver test.
Is fatty liver serious?
Simple fatty liver is common and reversible with weight loss and exercise. In a minority it progresses to inflammation, scarring and cirrhosis, so it should be assessed with a FibroScan, especially in people with diabetes.
Which symptoms of liver disease are an emergency?
Vomiting blood, black stools, confusion or drowsiness, jaundice with bleeding, fever or pain with ascites, and very low urine output all need hospital care the same day.
How often should people with diabetes check their liver?
Guidelines suggest people with type 2 diabetes be assessed for fatty liver and scarring, commonly with liver tests, a FIB-4 score and FibroScan, and repeated at intervals their doctor advises — often every one to three years.
