Diabetes mellitus type 1 Diabetes mellitus type 1 Diabetes mellitus type 1, also known as type 1 diabetes, is a form of diabetes mellitus in which very little or no insulin is produced by the pancreas. Before treatment this results in high blood sugar levels in the body. The classic symptoms are frequent urination, increased thirst, increased hunger, and weight loss. Additional symptoms may include blurry vision, feeling tired, and poor wound healing. Symptoms typically develop over a short period of time. The cause of type 1 diabetes is unknown. However, it is believed to involve a combination of genetic and environmental factors. Risk
Epigenetics of diabetes Type 2 Based on this study further investigation proved that if hypomethylation was induced, then the individual was far more likely to develop type 2 diabetes than those who led a healthy lifestyle. This proven presence of low methylation at certain sites could be used to diagnose diabetes 2 in individuals earlier in future treatment. Studies in 2011 have shown that insulin resistance (IR), the hallmark of type 2 diabetes, may also involve epigenetic control as a contributing factor. Promoter methylation of the mitochondrial transcription factor A(TFAM) gene, an important gene essential for mitochondrial DNA maintenance, was associated with IR in adolescents.
