Fatty Liver Index - What is it?

The fatty liver index (FLI) was developed by Italian researchers. Taking into account the body mass index (BMI), waist circumference, triglycerides and gamma-GT, a guideline value is determined by probability calculation.

According to said researchers, this guideline value can be used to determine the probability of non-alcoholic fatty liver. If the FLI is above 60, fatty liver is 78% likely. However, if the FLI is less than 30, the probability is very low. An FLI of 20 or less is said to rule out fatty degeneration with 91% probability.

Everything between 30 and 60 is a kind of gray area. The probabilities in this range are too imprecise to make a statement. In that case, it is imperative to consult a doctor to get a more precise diagnosis, e.g. with an ultrasound examination, should you suspect a non-alcoholic fatty liver.
