Another name for it is hepatic steatosis. More than the normal amount of fat builds up and when it becomes too much, there are health risks at stake. The liver is necessary to process nutrients from what you take in and to filter all harmful substances from your blood. When there is too much fat in the liver, the liver gets inflamed and eventually leads to scarring and liver damage. When a person drinks a lot of alcohol, the disease is called alcoholic-fatty-disease, and if they don´t drink it is called non-alcoholic-fatty-liver-disease. Needless to say, any damage to the liver is very hard to reverse and would have a hard impact on the way of living.
