Diabetes management goal of diabetes care, although recent research suggests that the complications of diabetes may be caused by genetic factors or, in type 1 diabetics, by the continuing effects of the autoimmune disease which first caused the pancreas to lose its insulin-producing ability. Because blood sugar levels fluctuate throughout the day and glucose records are imperfect indicators of these changes, the percentage of hemoglobin which is glycosylated is used as a proxy measure of long-term glycemic control in research trials and clinical care of people with diabetes. This test, the hemoglobin A1c or glycosylated hemoglobin reflects average glucoses over the preceding
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
