Nonalcoholic fatty liver disease: a frequent condition in type 2 diabetic patients

Nonalcoholic fatty liver disease represents an excessive fat accumulation in the liver of patients with no other liver disease and no history of alcohol abuse. It is associated with insulin resistance, being more prevalent in obesity and type 2 diabetes. Our aim was to assess the prevalence of fatty liver and nonalcoholic steatohepatitis in patients with type 2 diabetes and to evaluate the influence of obesity on its prevalence.

The prevalence of liver steatosis in our group was 87.1 %, with no significant differences between men and women. Patients with steatosis had higher abdominal circumference, body mass index (BMI; p = 0.001), and serum triglyceride (p
