Weight loss through improved diet and increased physical activity remains the cornerstone therapy for NAFLD, while pioglitazone, vitamin E, and bariatric surgery offer additional clinical benefits.
This review summarizes current clinical approaches to diagnosing and managing NAFLD, highlighting lifestyle modification as the cornerstone of therapy alongside emerging pharmacological options.
Non-alcoholic fatty liver disease (NAFLD) ranges from simple steatosis to nonalcoholic steatohepatitis (NASH), leading to fibrosis and potentially cirrhosis, and it is one of the most common causes of liver disease worldwide. NAFLD is associated with other medical conditions such as metabolic syndrome, obesity, cardiovascular disease and diabetes. NASH can only be diagnosed through liver biopsy, but noninvasive techniques have been developed to identify patients who are most likely to have NASH or fibrosis, reducing the need for liver biopsy and risk to patients. Disease progression varies between individuals and is linked to a number of risk factors. Mechanisms involved in the pathogenesis are associated with diet and lifestyle, influx of free fatty acids to the liver from adipose tissue due to insulin resistance, hepatic oxidative stress, cytokines production, reduced very low-density lipoprotein secretion and intestinal microbiome. Weight loss through improved diet and increased physical activity has been the cornerstone therapy of NAFLD. Recent therapies such as pioglitazone and vitamin E have been shown to be beneficial. Omega 3 polyunsaturated fatty acids and statins may offer additional benefits. Bariatric surgery should be considered in morbidly obese patients. More research is needed to assess the impact of these treatments on a long-term basis. The objective of this article is to briefly review the diagnosis, management and treatment of this disease in order to aid clinicians in managing these patients.
Katherine J. P. Schwenger (Wed,) conducted a review in Non-alcoholic fatty liver disease (NAFLD). Clinical approaches (diet, physical activity, pharmacotherapy, bariatric surgery) was evaluated. Weight loss through improved diet and increased physical activity remains the cornerstone therapy for NAFLD, while pioglitazone, vitamin E, and bariatric surgery offer additional clinical benefits.
