Today, we are here to talk about a problem that you may have overlooked, adolescent NAFLD. The improvement of living standards and inappropriate lifestyles are very popular among adolescents, such as binge drinking and binge eating, and inactivity. In both developing and developed countries, the prevalence of obesity in children is higher than that in adults and is on the rise, and NAFLD has become the most frequent chronic liver disease in pediatrics. 2008, the detection rate of simple obesity in 10 primary and secondary schools in a city was 18.4%; in 2009, the prevalence of overweight and obesity in high school students in a city was 16.3% and 8.5%, respectively, compared to 13.7% in 2001. The prevalence of overweight and obesity in a city high school students was 16.3% and 8.5% respectively in 2009, compared to only 13.7% and 3.9% in 2001, and NAFLD reached 74% in obese individuals. The health risk of NAFLD has not yet been fully revealed in China, but it has been shown to be very serious in some countries in Europe and the United States. For example, the number of deaths from end-stage liver disease due to NAFLD in the United Kingdom has increased four times compared to 30 years ago, and the number of liver transplantation cases due to fatty liver has risen to the first place, and the number of liver transplantation due to fatty liver in the United States has risen to the second place. The graph above tells us very clearly the risk of moving from simple fatty liver to steatohepatitis and the proportion of cirrhosis with liver fibrosis up to the development of hepatocellular carcinoma. Non-alcoholic fatty liver disease and its menacing yet very insidious. The threat to the liver comes after 20 years. It follows that non-alcoholic fatty liver disease is far less of a threat to the health of our generation than it is to our children, in whom non-alcoholic fatty liver disease will be the greatest health threat in the next 20, 30 years! So, exercise! Please take your kids with you.
