Abstract
Nonalcoholic fatty liver disease (NAFLD) is classically characterized by hepatic steatosis without any other etiological agents of excess fat accumulation in the liver. NAFLD is a wide range of conditions ranging from simple steatosis to nonalcoholic steatohepatitis, even to fibrosis and cirrhosis that can possibly progress to liver failure or hepatocellular carcinoma. The risk of fatty liver increases with increasing components of metabolic syndrome. We aim to study prevalence of non-alcoholic fatty liver disease among patients attending outpatient clinics at Suez Canal university hospital. A descriptive cross sectional Study was conducted on 175 patients after obtaining informed consent from each participant, structured interview-based questionnaire was used.
Our result showing that using the ultrasonography criteria for the diagnosis of NAFLD, the prevalence of NAFLD in our study was 76 patients (43.4%).On the other hand metabolic syndrome (MetS) was found among 94 patients (53.7) % of our study sample according to the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III).
There were statistical differences in BMI, WC, TG, LDL-C, HDL-C between NAFLD patients and non- NAFLD patients
NAFLD has become a common diagnosis in clinical practice of several medical specialties, and its prevalence in the general population is increasing together with obesity, type 2 diabetes and the metabolic syndrome. Prospective studies with long-term follow-up are necessary to better define the natural history of NAFLD and its incidence both in the general populations and in Special groups. Genetic studies are also necessary to determine to what extent the genetic background predisposes to NAFLD development and progression to advanced liver disease.
