But there is another form of liver disease, not connected to alcohol but, like so many conditions these days, related to obesity and type 2 diabetes.
A fatty liver has been described as yellow, like foie gras (pate made from the liver of a specially fattened duck or goose) and it may also be enlarged.
Many will have no idea they have it and, alarmingly, some experts are predicting N.A.F.L.D will overtake alcohol related liver disease as the most common cause of liver disease in the UK in the next few years.
Non alcoholic fatty liver disease is a spectrum condition that starts with the build up of fat cells in the liver and in some cases, can progress to inflammation and scarring.
Overweight people are more prone because they have higher levels of fats circulating in their blood, and lay down fat not only under the skin, but in and around their organs.
