Diabetes mellitus type 2 estimated that 20% of people with diabetes in the United States do not realize that they have the disease. Diabetes mellitus type 2 is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. This is in contrast to diabetes mellitus type 1 in which there is an absolute insulin deficiency due to destruction of islet cells in the pancreas and gestational diabetes mellitus that is a new onset of high blood sugars associated with pregnancy. Type 1 and type 2 diabetes can typically be distinguished based on the presenting circumstances. If the diagnosis is
Epigenetics of diabetes Type 2 in patients with Type 2 Diabetes is retinopathy which causes many patients to go blind. Studies showed that retinal damage persisted even after the reversal of hyperglycemia in dogs. Studies with streptozotocin injected Type 1 diabetes rats showed that the re-institution of glycemic control after a short period of hyperglycemia had protective effects in the eyes, including reduction in parameters of oxidant stress and inflammation. However, specimens with prolonged diabetes failed to show similar protection. It was then seen with endothelial cells (which line blood vessels) cultured in high glucose that there was a sustained increase in the expression of
