Unneeded fat is retained in the liver in the condition known as NAFLD. An excessive quantity of fat in the liver that is unrelated to alcohol consumption is referred to as NAFLD. NAFLD is characterised histologically by a wide range of liver damage, including simple steatosis, nonalcoholic steatohepatitis, and liver cirrhosis linked to nonalcoholic steatohepatitis. The pathogenic characteristics of non-alcoholic steatohepatitis (NASH) are hepatocellular damage and consequent inflammation in the liver tissue. In 15 to 20% of NASH patients, fibrosis, cirrhosis, or possibly cancer will develop. Lipid buildup in the hepatocyte is the pathological defining feature of NAFLD, indicating a direct association between faulty lipid metabolism and NAFLD. Indeed, abnormal lipid metabolism due to other diseases can also lead to NAFLD. According to population-based abdominal imaging studies, at least 25% of American people have fatty livers. The total frequency of NAFLD in the general population in India is nearly 40%.
