Microvascular Abnormalities in Diabetes Mellitus
Diabetes is a group of diseases that result from the lack of or resistance to insulin. These two situations are the large-scale and most basic explanation for all of the abnormalities in diabetes mellitus types 1 and 2, respectively. The biochemistry and consequent anatomic and physiologic abnormalities in these diseases differ.
Biochemical abnormalities explain the macro- and micro-vascular abnormalities. For every chronic complication there is an anatomic (i.e. vascular) and a biochemical explanation. The acute complications such as diabetic ketoacidosis, hyperosmolar coma and hypoglycemic episodes are mainly explained on the basis of biochemical abnormalities that will be discussed separately.
