INS and type 1 diabetes mellitus: It is classified into three major disease types [2] as follows: Type 1 Diabetes (T1D) [3] is caused by the destruction of the beta-cells in the pancreatic islets of Langerhans where insulin is produced and secreted; Type 2 Diabetes (T2D) is caused either by a decreased insulin secretion by the pancreas or by some kind of “resistance” to insulin developed by the body [4]; and finally, Gestational Diabetes (GD) may arise during pregnancy in 2%–6% of cases and increase the risk of complications for both mother and child before and after childbirth [5].
