Question

Epidemiology and natural history of non-alcoholic fatty liver disease

Answer 1

Nonalcoholic fatty liver disease is an umbrella term for a range of liver conditions affecting people who drink little to no alcohol. As the name implies, the main characteristic of nonalcoholic fatty liver disease is too much fat stored in liver cells.

Nonalcoholic steatohepatitis, a potentially serious form of the disease, is marked by liver inflammation, which may progress to scarring and irreversible damage. This damage is similar to the damage caused by heavy alcohol use. At its most severe, nonalcoholic steatohepatitis can progress to cirrhosis and liver failure.

Hope this helps.

Answer 2

Answer:

Nonalcoholic fatty liver disease includes a spectrum of liver disease that ranges from simple fat accumulation in the liver to necroinflammation, fibrosis, cirrhosis, and hepatocellular carcinoma, which in essence represent the stages of the natural history of NAFLD.
