However, up to 20% of patients with type 2diabetes will ultimately develop profound insulin deficiency requiring replacement therapy so that IDDM and NIDDM were misnomers. The normal adult pancreas contains about 1 million islets which are scattered throughout the exocrine parenchyma.costa rica resort The core of each islet consists of beta cells that produce insulin, and is surrounded by a cortex of endocrine cells that produce other hormones including glucagon, somatostatin and pancreatic polypeptide. Pro insulin in the pancreatic beta cells is cleaved to release insulin and equimolar amounts of inert C-peptide. Measurement of C-peptide can be used to assess endogenous insulin secretory capacity. An acute first phase of insulin secretion occurs in response to elevated blood glucose, followed by a sustained second phase. These are the information regarding the aetiology and pathogenesis of diabetes.
