Insulin resistance the resistance increases and compensatory insulin secretion fails. The elevated insulin levels also have additional effects (see insulin) that cause further abnormal biological effects throughout the body. The most common type of insulin resistance is associated with overweight and obesity in a condition known as the metabolic syndrome. Insulin resistance often progresses to full Type 2 diabetes mellitus (T2DM) or latent autoimmune diabetes of adults. This often is seen when hyperglycemia develops after a meal, when pancreatic β-cells are unable to produce sufficient insulin to maintain normal blood sugar levels (euglycemia) in the face of insulin resistance. The inability of
Insulin analog with zinc in the blood, forming hexamers. Insulin in the form of a hexamer will not bind to its receptors, so the hexamer has to slowly equilibrate back into its monomers to be biologically useful. Hexameric insulin delivered subcutaneously is not readily available for the body when insulin is needed in larger doses, such as after a meal (although this is more a function of subcutaneously administered insulin, as intravenously dosed insulin is distributed rapidly to the cell receptors, and therefore, avoids this problem). Zinc combinations of insulin are used for slow release of basal insulin. Basal insulin support is
