Background: Type 2 diabetes (T2DM) aetiology has been linked to the liver. It is crucial for maintaining normal glucose levels, and it has been proposed that insulin resistance syndrome causes hepatic dysfunction, which then results in T2DM. Glycosylation of haemoglobin results in the formation of HbAlc, a glycated haemoglobin. This value displays a person's glycaemic state for the last two to three months. In certain groups, markers of hepatic function, notably g-glutamyltransferase (GGT) and alanine aminotransferase (ALT), predict the occurrence of T2DM
