Core Tip

Core Tip: Diabetes mellitus (DM) due to diseases of the exocrine pancreas, diabetes of exocrine pancreas (DEP), is a common but underrecognized clinical entity. Post-pancreatitis DM (PPDM), which develop after pancreatitis, is classified as a subtype of DEP. The PPDM can develop even after acute pancreatitis; it is termed as post-acute pancreatitis DM. It differs in pathogenesis and natural history from type 1 and type 2 DM. There is a loss of pancreatic endocrine tissue, fibrosis and a component of autoimmunity. Both insulin deficiency and resistance play a role in this process. There are a number of knowledge gaps in diagnostic criteria, natural history and treatment options of PPDM.
