Are You at Risk for Liver Disease?
Fatty liver disease is silent, but it's often reversible when caught early. One simple number, your FIB-4 score, can show where you stand.
Liver Education Advocates is proud to support NIMBLE, a research study from the National Institutes of Health (FNIH) focused on improving how doctors diagnose metabolic liver disease.
Ask your doctor for a FIB-4
Your liver can be in trouble long before you feel anything.
Fatty liver disease, medically called MASLD (metabolic dysfunction-associated steatotic liver disease), affects roughly 1 in 3 adults in the U.S. Most people who have it don’t know. It usually causes no pain and no obvious symptoms, which is why it’s called a silent disease.
Left unchecked, fat in the liver can lead to inflammation (MASH), scarring (fibrosis), cirrhosis, liver cancer, and liver failure.
But here’s the hopeful part:
- It’s reversible when found early. In the early stages, the liver can heal.
- Prevention is the best treatment. Stopping damage before scarring sets in is far easier than treating it afterward.
- Lifestyle changes work. Nutrition, movement, and healthy weight loss get the best results.
The first step is knowing your risk.
Know Your Risk Factors
Anyone can develop fatty liver disease, but some people are at greater risk. Do any of these apply to you?
Type 2 diabetes
People with type 2 diabetes are at much higher risk. Studies estimate that more than half of people with type 2 diabetes have fatty liver disease, and they are more likely to develop the scarring that leads to cirrhosis. The connection is insulin resistance, which drives fat buildup in the liver. Liver disease can in turn make blood sugar harder to control.
If you have type 2 diabetes or prediabetes, ask your doctor about a FIB-4 score. The American Diabetes Association recommends this screening for people with diabetes.
BMI over 30
Carrying excess weight, especially around the belly, is one of the strongest drivers of fatty liver disease. A BMI of 30 or higher (the range classified as obesity) puts you at significantly greater risk.
Other risk factors
- Prediabetes or insulin resistance
- High cholesterol or high triglycerides
- High blood pressure
- A large waist circumference
- A family history of liver disease
- Age 50 or older
A note for people who think “that’s not me”: Fatty liver disease can affect people at every size, including people with a BMI under 30 and children. If you have any of the risk factors above, the safest move is to check.
What Is a FIB-4 Score?
A simple, no-cost way to see if your liver may be scarred.
FIB-4 (Fibrosis-4 Index) is a quick calculation that estimates the likelihood of liver scarring. It uses information from tests you may already have had:
- Your age
- Two liver enzymes (AST and ALT)
- Your platelet count
It comes from a standard blood test, usually part of routine bloodwork. No biopsy, no needles beyond the blood draw, and no special equipment. Your doctor can calculate it, or you can ask for your lab values and we’ll show you how.
What your score means
| FIB-4 Score | What it suggests | What to do |
|---|---|---|
| Below 1.3 (below 2.0 if you’re 65 or older) | Low likelihood of advanced scarring | Keep up healthy habits. Ask your doctor how often to recheck. |
| 1.3 to 2.67 | Uncertain, so more information is needed | Talk to your doctor about follow-up testing, such as a liver stiffness scan. |
| Above 2.67 | Higher likelihood of advanced scarring | See your doctor or a liver specialist soon. |
FIB-4 is a screening tool, not a diagnosis. Only your healthcare provider can interpret your results in the context of your overall health.
The Good News: You Have Power Here
Fatty liver disease is one of the few serious conditions where your daily choices can change the outcome.
Research shows that losing 7–10% of your body weight can reduce liver fat and inflammation, and in many people it can improve early scarring. Even without major weight loss, healthier eating and regular movement improve liver health.
Start here:
- Eat more whole foods. Fruits, vegetables, whole grains, beans, fish, and olive oil. The Mediterranean style of eating is well studied for liver health.
- Cut back on added sugar and processed foods. Sugary drinks and sodas are a good first swap.
- Move your body. Aim for about 150 minutes a week. Brisk walking counts.
- Limit or avoid alcohol. Ask your doctor what’s safe for you.
- Manage your diabetes, cholesterol, and blood pressure. Work with your healthcare team.
- Get checked regularly. Early detection is what makes reversal possible.
Research Spotlight
Help Shape the Future of Liver Diagnosis (NIMBLE)
Already know your FIB-4? You could help advance liver science.
Liver Education Advocates is proud to support NIMBLE, a research study from the Foundation for the National Institutes of Health (FNIH). Today, diagnosing the extent of liver damage often requires a liver biopsy, which is invasive and carries risks. NIMBLE is evaluating whether blood tests and non-invasive imaging can provide reliable information about liver health compared with biopsy. The findings may help lead to new tools that reduce the need for biopsies in the future.
This study does not involve any treatment or medication.
Eligible participants may:
- See medical staff for study-related care at no cost
- Receive liver imaging, a liver biopsy, and study-related lab tests at no cost
- Receive compensation for study-related time and travel
You may be eligible if you:
- Are 18–75 years old
- Have certain health conditions, such as high cholesterol, type 2 diabetes, or a BMI of 25 or higher
- Have a FIB-4 score above 1.3 (or above 2.0 if you’re over 65)
- Are willing to undergo a liver biopsy
Additional eligibility criteria apply. The study team will review these with you.
Tip: If you know your FIB-4 score, share it when you contact the study team. It can help speed up your initial screening.
FAQs
No. Early fatty liver disease usually has no symptoms, so testing is the only reliable way to know.
No. MASLD is not caused by alcohol. It’s linked to metabolic factors like weight, insulin resistance, and cholesterol.
In its early stages, yes, often through lifestyle changes. Advanced scarring (cirrhosis) is harder to reverse, but even then, treatment and healthy habits can slow or stop further damage. That’s why early detection matters.
Anyone with type 2 diabetes, prediabetes, obesity, or other metabolic risk factors, and anyone concerned about their liver. Ask your doctor.
It’s reassuring, but it isn’t a guarantee. Keep up healthy habits and ask your doctor how often to recheck.
Don’t panic. A high score means it’s time for a closer look, not that you have advanced disease. Your doctor may order a liver stiffness scan or refer you to a specialist.
No. FIB-4 is a screening estimate from a blood test. A biopsy directly examines liver tissue. Research like NIMBLE aims to make non-invasive tests reliable enough to reduce the need for biopsies.
