metaboliqWhat fatty liver is
The liver stores some fat normally. Fatty liver means it is holding more than about 5% of its weight as fat. In 2023 the international liver societies renamed the common form MASLD: fat in the liver together with at least one metabolic risk factor such as a large waist, raised blood sugar, raised blood pressure or abnormal cholesterol.
Pooled across Indian studies, about 38.6% of adults have it, and it is found in many people who are not heavy by Indian standards.
Symptoms, in women and men
Most people have no symptoms at all; it is usually found on a scan or a blood test done for something else. Some notice tiredness, or a dull ache or fullness under the right ribs.
Women with PCOS or insulin resistance are more likely to have it, and the symptoms are the same. Yellow eyes or skin, a swollen belly or legs, vomiting blood or confusion are signs of advanced liver disease and need a doctor the same day.

Causes
The main drivers are insulin resistance, extra fat around the waist, type 2 diabetes or prediabetes, raised triglycerides and a diet high in sugar, sweet drinks and refined flour. Alcohol adds to it; when both are present the term is MetALD.
- Insulin resistance, often before blood sugar is raised.
- A large waist, even at a normal BMI.
- Sweet drinks, sweets and refined flour, every day.
- Little activity, and poor sleep.
- Alcohol, at any level, makes it worse.
Grade 1, 2 and 3 on an ultrasound
An ultrasound report often grades fatty liver from 1 (mild) to 3 (severe) by how bright the liver looks. The grade describes fat, not scarring, so it does not say how much damage there is.
Scarring, called fibrosis, is what decides the outlook. It is estimated with the FIB-4 score from routine blood tests, and with liver elastography (FibroScan) when the score is not low.

Is fatty liver dangerous?
For most people it stays as fat alone. In a minority, inflammation (MASH) leads to scarring over years, and a few reach cirrhosis. People with fatty liver are also at higher risk of heart disease, which is the commonest serious problem they face.
That is why the useful questions are how much scarring there is and how the metabolic risks are doing, not only the ultrasound grade.

The blood tests that matter
A liver function test (ALT, AST, GGT), a lipid profile, HbA1c and fasting insulin show how the liver and the metabolism behind it are doing. A normal ALT does not rule fatty liver out.

What helps it improve
Steady fat loss is the most reliable treatment. In a study of 293 adults with inflammatory fatty liver, those who reduced body weight by 10% or more through lifestyle change had the highest rates of resolution and of scarring going backwards.
The European guideline recommends a Mediterranean-style pattern, regular activity of 150 to 300 minutes a week, and avoiding alcohol. For an Indian plate that means dal, vegetables, curd, whole grains and nuts in place of refined flour, sweets and fried snacks.
- Cut sweet drinks, packaged juice and added sugar first.
- Swap maida and white rice for whole grains, millets and dal.
- Protein at every meal: dal, paneer, curd, eggs, fish or chicken.
- Walk after meals, and add strength training twice a week.
- No alcohol while the liver recovers.
