What is fatty liver?
Fatty liver means extra fat has built up inside the liver cells. It is very common — studies suggest that around 1 in 3 adults in India has it, and most do not know, because it usually causes no symptoms. It is often found by chance on an ultrasound done for something else.
Doctors now call the most common type MASLD (metabolic dysfunction-associated steatotic liver disease). Your reports may use older names such as NAFLD or MAFLD — they describe the same condition. It is linked to weight, blood sugar, blood pressure and cholesterol, rather than to alcohol alone.
Is it serious?
For most people, fatty liver stays mild. But in some, the fat causes inflammation (MASH), which over years can lead to scarring (fibrosis), then cirrhosis and, in a small number, liver cancer.
The amount of scarring — not the amount of fat — decides the outlook. Two people with the same ultrasound report can have very different livers. That is why the next step after an ultrasound is to check for scarring.
Fatty liver is also a warning sign for the heart: heart disease and diabetes are the commonest serious problems in people with fatty liver. Treating it well protects the heart too.
Who is at risk?
- Extra weight — for Indians, a BMI of 23 or more is already overweight, and 25 or more is obese
- Belly fat — waist 90 cm (35 inches) or more in men, 80 cm (31.5 inches) or more in women
- Diabetes or prediabetes, high blood pressure, high triglycerides or low "good" cholesterol
- PCOS, snoring with sleep apnoea, an underactive thyroid
- Lean fatty liver: many Indians develop fatty liver at a normal weight, especially with belly fat or diabetes
- Alcohol adds to the damage. Fat plus regular drinking (sometimes called MetALD) harms the liver faster than either alone
Fatty liver on your ultrasound — what next?
An ultrasound shows fat, but it cannot tell how much scarring there is. The "grade" of fatty liver on the report (grade 1, 2 or 3) reflects how bright the liver looks, and does not reliably show how damaged it is. Normal liver blood tests (ALT/SGPT) also do not rule out scarring.
- Blood tests: liver function tests, platelet count, blood sugar and HbA1c, cholesterol profile, and tests for hepatitis B and C to rule out other causes.
- FIB-4 score: a simple calculation from your age and three routine blood results (AST, ALT, platelets). It costs nothing extra and tells whether scarring is unlikely.
- FibroScan (liver stiffness test): a quick, painless scan — like an ultrasound — done when the FIB-4 score is not clearly low. Available at both Hayat Hospital and Apollo Clinic, Ulubari, so it can usually be done on the day of your consultation.
- Liver biopsy is rarely needed; it is reserved for cases where the answer is still unclear.
| Result | What it usually means | Typical next step |
|---|---|---|
| FIB-4 below 1.3 | Significant scarring is unlikely | Lifestyle changes, treat sugar/BP/cholesterol, recheck every 1–3 years |
| FIB-4 1.3 or above | Scarring cannot be ruled out | FibroScan |
| FibroScan below 8 kPa | Low risk | Lifestyle changes and periodic review |
| FibroScan 8 kPa or above | Possible significant scarring | Specialist assessment and closer follow-up |
Cut-offs are from international guidelines and are a guide only — results are interpreted together with your other reports. For people over 65, different FIB-4 cut-offs apply.
Can fatty liver be reversed?
Yes. Fatty liver is one of the few liver diseases that can improve substantially with lifestyle change, and even early scarring can go back. Weight loss is the most effective treatment known:
| Weight lost | Effect on the liver | Example for an 80 kg person |
|---|---|---|
| About 5% | Liver fat falls | 4 kg |
| 7–10% | Inflammation improves | 6–8 kg |
| 10% or more | Scarring can regress | 8 kg or more |
Slow, steady loss of about 0.5–1 kg a week is safest. Crash diets can make the liver worse.
Food — practical changes for a Northeast Indian kitchen
- Fill half the plate with vegetables, a quarter with rice or roti, a quarter with dal, fish, egg, chicken or paneer. Reduce the rice portion rather than stopping it.
- Cut sugar in tea and limit biscuits, sweets, packaged juices and soft drinks — sugary drinks are one of the biggest drivers of liver fat.
- Limit fried snacks (pakora, puri, samosa) and maida-based foods; reuse of frying oil is especially harmful.
- Prefer whole fruit to fruit juice; choose fish, dal and seasonal vegetables often.
Movement
- Aim for 150 minutes a week of brisk walking or similar activity, plus muscle-strengthening exercise twice a week.
- Exercise lowers liver fat even if your weight does not change much — do not give up if the scale moves slowly.
Alcohol
Less is better. If there is significant scarring or cirrhosis, no alcohol at all is the safest choice.
Medicines
- There is no single pill that suits everyone with fatty liver. Treatment is chosen for your situation.
- If you have diabetes, some diabetes medicines also help the liver — these are chosen together with your physician or diabetologist.
- Newer medicines for fatty liver with significant scarring have been approved in some countries. Whether any is suitable for you is discussed in clinic.
- Cholesterol medicines (statins) are generally safe in fatty liver and protect the heart — do not stop them because of a liver report without advice.
- Avoid "liver tonics", detox products and unproven herbal remedies. They have no proven benefit for fatty liver, and some have caused serious liver injury.
Have an ultrasound report that says fatty liver?
Send your ultrasound and blood reports on WhatsApp before your visit. Consultations at Hayat Hospital and Apollo Clinic, Ulubari, and at outreach OPDs in Dimapur, Hojai, Tinsukia and Dibrugarh.
Other liver problems we treat
| Condition | What to know |
|---|---|
| Hepatitis B | Common in Northeast India and often silent. Long-term tablets can control it and protect the liver. Family members should be tested and vaccinated. |
| Hepatitis C | Can be cured in most people with a short course of tablets, usually 12 weeks. |
| Alcohol-related liver disease | Stopping alcohol is the single most important treatment; help with stopping is part of care. |
| Cirrhosis | Needs regular monitoring: an ultrasound (often with an AFP blood test) every 6 months to detect liver cancer early, and an endoscopy to look for swollen veins (varices), which can be treated by banding. |
| Abnormal liver tests or jaundice | Need a cause to be found. Jaundice from a blocked bile duct may need ERCP. |
| Autoimmune and other liver diseases | Less common conditions that are diagnosed with specific blood tests, scans and sometimes a biopsy. |
Get medical help urgently if you have liver disease and notice:
- Yellow eyes or skin that is new or worsening
- Vomiting blood, or black, tarry stools
- Confusion, unusual sleepiness or behaviour change
- A rapidly swelling tummy, or fever with tummy pain
Go straight to the nearest emergency department.
