Type 1 diabetes (T1D), previously known as juvenile diabetes, is an autoimmune disease that originates when very little or no insulin is produced by the islets of Langerhans (containing beta cells) in the pancreas. This is because the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. Type 1 diabetes occurs when your immune system, the body's system for fighting infection, attacks and destroys the insulin -producing beta cells of the pancreas . Type 1 diabetes is due to pancreatic islet B cell destruction predominantly by an autoimmune process, and these persons are prone to ketoacidosis. Review all information provided in the case to answer the following questions. Type I diabetes mellitus, formerly referred to as juvenile-onset diabetes mellitus or insulin-dependent diabetes mellitus. Insulin is normally synthesised in the pancreas by the b-cells of the islets of Langerhans in response to a glucose stimulus.
