Metabolic implications of pancreatic fat accumulation

Fat accumulation outside subcutaneous adipose tissue often has unfavourable effects on systemic metabolism. In addition to non-alcoholic fatty liver disease, which has received considerable attention, pancreatic fat has become an important area of research throughout the past 10 years. While a number of diagnostic approaches are available to quantify pancreatic fat, multi-echo Dixon MRI is currently the most developed method. Initial studies have shown associations between pancreatic fat and the metabolic syndrome, impaired glucose metabolism and type 2 diabetes mellitus. Pancreatic fat is linked to reduced insulin secretion, at least under specific circumstances such as prediabetes, low BMI and increased genetic risk of type 2 diabetes mellitus. This Review summarizes the possible causes and metabolic consequences of pancreatic fat accumulation. In addition, potential therapeutic approaches for addressing pancreatic fat accumulation are discussed. There is growing evidence that fat accumulation in the pancreas can have consequences for metabolic health. This Review discusses the methods for detecting pancreatic fat and the potential causes and pathogenic consequences of pancreatic fat accumulation.

Automated summary

Pancreatic fat plays a critical role in metabolic syndrome, impaired glucose metabolism, type 2 diabetes mellitus, and insulin secretion. Various diagnostic methods are available to quantify pancreatic fat accumulation.
