Although drinking too much alcohol can cause fat build-up in the liver, fatty liver disease affects people who consume little or no alcohol.
Instead, the main culprit is excess weight which causes extra fat to get stored in the liver and is associated with dyslipidaemia (abnormally high LDL cholesterol levels, low HDL levels, or both), high blood pressure, and diabetes.
As the number of overweight people has increased, so too has the prevalence of the condition.
