Type 2 diabetes mellitus is a heterogeneous disease which is characterized by variable degrees of insulin resistance, impaired insulin secretion and increased glucose production. An association exists between diabetes and liver injury. Liver pathology among diabetics is similar to that of alcoholic liver disease, including steatosis, steato-hepatitis, fibrosis and cirrhosis. Elevated serum activity of the two aminotransferases, AST and ALT, is the most frequently measured indicator of liver disease and occurs in diabetics more frequently than in the general population. The cause effect relationship between liver diseases and T2DM remains ambiguous. Which provides an overview of the evidence for the impact of chronic liver diseases on T2DM and examines up-to-date studies about the possible underlying mechanism. All groups of people are advised to read this book.
