Consequently, glucose remains in the blood leading to a high blood sugar level. Exactly what causes the immune system to do this is not yet clearly understood. Type 2 diabetes mellitus consists of an array of dysfunctions characterized by hyperglycemia and resulting from the combination of resistance to insulin action, inadequate insulin secretion, and excessive or inappropriate glucagon secretion. 2.
