You Have Risk Factors for Fatty Liver
Obesity, type 2 diabetes, and high triglycerides raise the chance of fatty liver. One-third to two-thirds of people with type 2 diabetes have NAFLD.
AI Summary The MAFLD score is a noninvasive estimate of how likely you are to have fatty liver tied to metabolic health. It uses your age, BMI, and blood sugar status, and results fall into low, moderate (−1.455 to 0.676), or high (above 0.676) groups. It estimates risk. It does not diagnose or measure scarring on its own. A high score may lead to specialist evaluation, more testing, lifestyle changes such as weight loss, and regular follow-up.

MAFLD Score: What It Is and How to Read Your Result
Medically Reviewed.
The MAFLD score is a calculated number that estimates how likely it is that you have fatty liver tied to metabolic factors, such as excess weight, type 2 diabetes, or insulin resistance. MAFLD stands for metabolic dysfunction–associated fatty liver disease.
It uses information your care team already has, such as your age, body mass index (BMI), and blood sugar status. It needs no biopsy and can be repeated over time. It estimates risk and does not diagnose on its own.

FATTY LIVER RISK SCORE
What Is the MAFLD Score?
The MAFLD score is a noninvasive assessment tool. It estimates the risk and severity of fatty liver disease linked to metabolic factors, such as obesity, diabetes, high cholesterol, or insulin resistance.
Unlike a liver biopsy, the score uses clinical and lab data your care team may already have. That makes it safe, convenient, and easy to repeat.
MAFLD stands for metabolic dysfunction–associated fatty liver disease. The name was created to describe fatty liver as a positive diagnosis tied to metabolic health, rather than with vague or stigmatizing terms. You may also see MASLD (metabolic dysfunction-associated steatotic liver disease), which is another name for nonalcoholic fatty liver disease (NAFLD). This page uses MAFLD because the score carries that name. To learn about the condition itself, see fatty liver disease.
The MAFLD score is built to flag the chance of liver fat. Other tools, such as the FAST score and the SAFE score, look at scarring (fibrosis) in people with fatty liver.
MAFLD Score at a Glance
- Estimates the likelihood of fatty liver tied to metabolic factors, without a biopsy.
- The equation uses age, BMI, and whether you have impaired fasting glucose or diabetes.
- Results fall into three groups: low, moderate, and high. The cutoffs are −1.455 and 0.676.
- A high score points to likely significant fatty liver. Specialist evaluation may be needed. It is not a diagnosis.
- Fatty liver is common. About 24% of U.S. adults have NAFLD, also called MASLD.
- People with no baseline fibrosis and stable metabolic risk can be rechecked with noninvasive scores every 2 to 3 years.
WHEN IT IS USED
Why Your Doctor May Suggest a MAFLD Score
The score is a screening and tracking tool. Your doctor may suggest it in these situations.
You Have No Symptoms Yet
Early fatty liver usually causes no symptoms and is often found at routine checkups. A score can flag early liver fat before you feel anything.
Your Doctor Wants to Track Your Liver over Time
Because the score uses routine measurements, your care team can repeat it and compare results from visit to visit.
You Are Checking Whether Changes Are Working
Doctors can use repeat scores to see how lifestyle changes or treatment affect liver fat risk. Imaging such as FibroScan can also track progress.
THE CALCULATION
What Goes into a MAFLD Score
The score combines a few routine health measures into one number. Your clinic or an online calculator does the math.
- Age
- Older age is part of the equation, because fatty liver becomes more likely as people age.
- Body mass index (BMI)
- A higher BMI raises the chance of fatty liver. BMI compares your weight with your height.
- Blood sugar status
- The equation asks whether you have impaired fasting glucose or diabetes (yes or no). Glucose or HbA1c results show insulin resistance or diabetes.
- Other markers in some versions
- Some descriptions of the score also include blood fats (triglycerides and cholesterol), liver enzymes (ALT and AST), blood pressure, or waist size. Ask your clinic which version it uses.
Good to know: Different clinics and calculators may use different inputs. Compare your score only with results from the same method.
YOUR RESULT
How to Read Your MAFLD Score
Results fall into three groups. These groups describe likelihood. They do not confirm or rule out disease.
| Score group | Score | What it suggests | What often happens next |
|---|---|---|---|
| Low | At or below −1.455 | Liver fat is likely normal or very mild. | Keep up a healthy lifestyle. |
| Moderate | −1.455 to 0.676 | Possible fatty liver with some fat buildup. | Lifestyle changes and monitoring. |
| High | Above 0.676 | Likely significant fatty liver. | Specialist evaluation. More testing or treatment may be needed. |
Only your doctor can interpret your score in the context of your health history and other test results.
SCORE LIMITATIONS EXPLAINED
What a MAFLD Score Cannot Tell You
It Estimates Likelihood, Not a Diagnosis
The score shows how likely fatty liver is. It does not confirm it. Your doctor may order imaging or other tests to check.
It Is Built on a Few Inputs
The equation uses age, BMI, and blood sugar status. It does not directly measure liver fat, inflammation, or scarring. A score in the low group does not rule out liver disease if you have symptoms or other test changes.
It Does Not Measure Scarring on Its Own
Fibrosis is a different question. Tests such as the FAST score, the SAFE score, and FibroScan address it. Scarring matters because it drives the risk of cirrhosis.
FATTY LIVER TEST COMPARISON
MAFLD Score Compared with Other Fatty Liver Tests
Each test answers a different question. Your care team picks based on your situation.
| Test | What it looks at | What it adds |
|---|---|---|
| MAFLD score | Age, BMI, blood sugar status | A quick, repeatable estimate of fatty liver likelihood |
| FAST score | FibroScan results plus AST blood test | Estimates risk of MASH with significant fibrosis |
| SAFE score | Blood markers, liver tests, and other data | Estimates fibrosis severity in people with fatty liver |
| FibroScan | Ultrasound-based scan of the liver | Measures stiffness (scarring) and liver fat in about 10 to 15 minutes |
| Liver biopsy | A tissue sample under a microscope | The most precise diagnostic procedure, but invasive |
NEXT STEPS
What to Do After You Get Your Score
Talk Through the Result with Your Doctor
Ask what your score group means for you, what other tests make sense, and when to repeat the score. Bring a list of your medicines and your recent lab results.
Make Lifestyle Changes the Base of Your Plan
Weight loss through lifestyle change is the cornerstone of MAFLD care. Losing at least 5% of body weight is needed to reduce liver fat. About 7% to 10% is typically needed to resolve steatohepatitis, and more than 10% can improve fibrosis.
Plan Follow-Up
People with no fibrosis and stable metabolic risk can be rechecked every 2 to 3 years. People with significant fibrosis or uncontrolled metabolic conditions should be checked yearly. People with cirrhosis need liver cancer screening every 6 months.
Ask About Treatment Options if Your Risk Is High
A specialist may discuss medicines or procedures. Related pages cover resmetirom, vitamin E, and bariatric and endoscopic therapies. Your specialist decides what fits you.

Common Questions
Answers to Common MAFLD Score Questions
What is a high MAFLD score?
Above 0.676 is the high group, which suggests likely significant fatty liver. A score between −1.455 and 0.676 is moderate and suggests possible fatty liver. A score at or below −1.455 is low. Your doctor interprets the number with your other results.
Does a high MAFLD score mean I have liver disease?
No. A high score means fatty liver is likely, and it may prompt specialist evaluation. A diagnosis needs your doctor to review your history and often other tests, such as imaging.
What information is used to calculate a MAFLD score?
The equation uses your age, BMI, and whether you have impaired fasting glucose or diabetes. Other versions may add blood fats, liver enzymes, blood pressure, or waist size.
Can I lower my MAFLD score?
Yes. Weight loss of at least 5% is needed to reduce liver fat. Eating a Mediterranean-style diet and staying active also help. Early fatty liver can often be reversed with sustained weight loss, a balanced diet, and exercise.
Is the MAFLD score the same as a FibroScan?
No. The MAFLD score estimates the chance of fatty liver. FibroScan measures liver stiffness and fat with ultrasound-based technology. Scores such as FAST and SAFE address scarring in people with fatty liver.
