The investigators hypothesize that low iron storages protects from and down-grades non-alcoholic fatty liver disease.

The aim of the study is to show the association between the severity of Non-alcoholic fatty liver disease to low iron status.

Patients that will pass a CT scan that includes the abdomen will be asked to participate at our study. These patients will be divided into two groups - with and w/o fatty liver. The severity of fatty liver will be determined using the CT scan (as well as other parameters, such as the size of subcutaneous fat layer). Within 72 hours from the scan, a venous blood test will be taken from the enrolled patients (together with a BMI calculation and a blood pressure measurements). In the blood test we will examine liver functions, iron status etc.

This is a preliminary study that will aid in planning future strategies to treat or even prevent fatty liver (one of the epidemics of our century).
