Obesity levels are now so high that many children are suffering from disease more commonly associated with alcohol abuse. Many of them will develop cirrhosis, and some will require liver transplants.
Studies show that millions of children in the U.S. are suffering from "non alcoholic liver disease" which is caused by a build-up of fat within liver cells. This prevents the organ from functioning properly.
According to the Telegraph:
“The condition increases the risks of heart disease, strokes and type 2 diabetes, and can lead to cirrhosis -- scarring of the liver -- which is often not detected until it is too late ... There is no medical treatment for the disease, but the extent of it can be reduced by weightloss and improvements in diet.”
