Core Tip
Core tip: The presented results indicate that male gender and a higher body mass index (BMI) are risk factors for advanced fibrosis in morbidly obese patients. There is also a positive correlation between cigarette smoking and liver stiffness in men. Our study highlights the fact that even in the upper BMI ranges, higher BMI bears greater risk for advanced disease. Therefore, in the morbidly obese population it may seem useful to emphasize the importance of weight reduction, even within the range of obesity.
