Fat in the liver typically develops when a person consumes more fat and sugars than his or her body can handle. This is more common in people who are overweight or obese, but can also occur in adults with healthy body weights. If the fat builds up to more than 5% of the liver, then the liver is considered to be a fatty liver. Although having this condition may not cause any immediate harm, there is a concern that the extra fat in the liver might make the liver vulnerable to further injury such as inflammation and scarring.
