The American liver foundation says that if more than five to 10 percent of the liver’s weight is fat, then it is called a fatty liver.
Having high levels of fat in your liver is associated with an increased risk of other health problems, such as diabetes, high blood pressure and kidney disease.
People are more likely to develop NAFLD as a result of a number of factors. For example, if you are insulin resistant, as people can be when they have polycystic ovary syndrome. Non-alcoholic fatty liver disease tends to develop in people who are overweight or obese or have diabetes, high cholesterol or high triglycerides.
Some people get fatty liver disease without having any pre-existing conditions.
