Diabetes mellitus type 2 state may occur; however, ketoacidosis is uncommon. Type 2 diabetes primarily occurs as a result of obesity and lack of exercise. Some people are more genetically at risk than others. Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to diabetes mellitus type 1 and gestational diabetes. In diabetes mellitus type 1 there is a lower total level of insulin to control blood glucose, due to an autoimmune induced loss of insulin-producing beta cells in the pancreas. Diagnosis of diabetes is by blood tests such as fasting plasma glucose, oral glucose tolerance
Epigenetics of diabetes Type 2 evidence that alteration in global DNA hypermethylation is associated with increased risk of IR independent of established risk factors. Because epigenetic modifications are possibly reversible, this research suggests the potential for lifestyle or therapeutic interventions for insulin resistance. As shown by various studies, there are a number of genes that affect a person’s risk of contracting Type 2 Diabetes. The same applies for obesity, which has several loci in common with the disease. Both are polygenic, but it is possible to identify at least part of the regions via DNA assays. Among these regions is the fat mass and obesity
