Background:
Nonalcoholic fatty liver disease (NAFLD) represents a spectrum of liver disease characterized by excess of fat in liver which ranges from simple steatosis to nonalcoholic steato-hepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC) in the absence of excessive alcohol consumption.
Materials And Methods:
The study was carried out in 216 with serologically defined fatty liver. They underwent detailed history evaluation, clinical examination and anthropometric measurements, biochemical and serological tests. The cut-off values for central obesity were waist hip ratio (WHR) > 0.85 in women and > 0.9 in men.
Results:
The prevalence of NAFLD was highest in the age group of 31 to 60 years. It was more common in males than females. Twenty cases (11.7%) had discomfort at right upper abdomen. Hepatomegaly was found in 27 patients (13.2%), impaired glucose tolerance (IGT) in 29 (14.21%) and diabetes mellitus in 38 (18.63%) patients. Overweight or obesity was found in 110 (53.92%) cases and central obesity was seen in 129 (63.23%) patients. Hence, metabolic syndrome (according to International Diabetes Federation Criteria) was present in 62.25% cases of NAFLD. Alanine aminotransferase (ALT) more than upper limit of normal was found in 36.76% cases.
Conclusion:
Risk factors for NAFLD in Bangladesh are similar to reported from the rest of the world. Age more than 30 years, male sex, WHR > 0.9 in men and more than 0.85 in female, BMI more than 25, glucose intolerance are predictive factors for NAFLD.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...
