Weight reduction improves markers of hepatic function and insulin resistance in type-2 diabetic patients with non-alcoholic fatty liver

Objective

The incidence of non-alcoholic fatty liver disease (NAFLD) is increasing dramatically affecting up to 30% of the population worldwide. At present, treatment options are limited and pharmacological management of NAFLD has had disappointing results. Some of the best available evidence to improve NAFLD concerns lifestyle modification.

Objective

To detect the degree of weight reduction needed to improve the markers of hepatic function and insulin resistance in type-2 diabetics with NAFLD.

Methods

One hundred type-2 diabetic male patients with NAFLD were included into this study and divided into two equal groups. Group (A) received aerobic exercise training in addition to diet regimen. Group (B) received no treatment intervention.

Results

There was a 26.99%, 40.8%, 33.81%, 32.73%, 37.8% and 15 % reduction in mean values of Alkaline Phosphatase (ALP), Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Gamma - Glutamyltransferase (GGT) and Homeostasis Model Assessment-Insulin Resistance-index (HOMA-IR) and BMI respectively in group (A) at the end of the study. While there were significant differences between mean levels of the investigated parameters in group (A) and group (B) after treatment.

Conclusion

About 15 % reduction in BMI is effective to improve the liver condition and insulin resistance in type-2 diabetics with NAFLD.
