Background: Nonalcoholic fatty liver disease (NAFLD) is a reversible condition of fat accumulation that is associated with liver inflammation and can disrupt the normal activity of the liver. People with a diagnosis of NAFLD have a higher risk of all- cause mortality than the general population. The purpose of the present study was to determine, the efficacy of orlistat in the treatment of patients with NAFLD.

Methods: This semi-experimental study was performed on 45 fatty liver patients of the gastroenterology clinic of Imam Khomeini Hospital in Ardabil city in April 2016 to April 2017. Data was collected by a checklist which included demographic and clinical data such as age, sex, body mass index (BMI), alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol and result of ultrasound before and after orlistat consumption.

Results: The mean decrease in the variables examined was as follows: weight 8.3 kg, BMI 3.5 kg/m2, ALT 31.6 U/l, AST 18.1 U/l, cholesterol 15.5 mg/dl and TG 33.1 mg/dl. All of the upper indexes were decreased significantly following received drug.

Conclusions: Orlistat therapy was associated with significant decreases in ALT, AST, TG and cholesterol level. Orlistat is effective in weight loss, body mass index reduction and can be used to treat non-alcoholic fatty liver disease.
