ABSTRACT
Background Nonalcoholic fatty liver disease (NAFLD) is collection of lipids in hepatic tissues excluding other hepatic diseases and chronic alcohol intake. It may advance to nonalcoholic steatohepatitis or cirrhosis. Ultrasonography has high sensitivity and specificity for detecting nonalcoholic fatty liver disease. Objective Lack of sufficient information in this region on sonological prevalence of nonalcoholic fatty liver disease, lead us to design the survey and may also serve as reference for further researches. Method This is a cross sectional study with 600 participants, conducted at Gandaki Medical College Teaching Hospital, Province 4 of Nepal, from September to October 2017. Ethical approval is taken from the Institutional review board. The study group includes the participants referred for abdominal sonography from outpatient department. Result In present survey, 367 (61.2%) are female and 233 (38.8%) are male participants. The mean age is 41.6 years and median age is 38 years. The prevalence of nonalcoholic fatty liver in our observation is 229 cases (38.2%) of which, 102 cases (44.5%) are male and 127 cases (55.4%) are female participants. Normal liver was seen in 61.8%, Grade one fatty liver was discovered in 24.8%, Grade one in 12.6% and Grade three in 0.6%. The mean liver size in those with fatty liver was 14.1 cm. Conclusion Province 4 of Nepal is not exempt from the growing epidemic of nonalcoholic fatty liver disease with prevalence of 38.2%. The study shows that with higher grades of fatty liver, the size of liver is also increased and the mean age of the participants involved is also in the higher side of the spectrum.
