High insulin and normal blood sugar is the presence of insulin resistance. Insulin is the only hypoglycemic hormone in the body, and when insulin resistance occurs due to obesity and other reasons, insulin cannot exert the corresponding hypoglycemic effect. In order to avoid the rise of blood glucose, pancreatic beta cells will promote insulin secretion, and a situation of high insulin and normal blood glucose will occur. When the promoted insulin secretion still cannot control blood sugar, a state of high insulin and high blood sugar will occur, which means abnormal glucose tolerance or diabetes. Therefore, high insulin and normal blood glucose indicate the presence of insulin resistance in patients. In order to avoid the aggravation of insulin resistance, it is recommended to do the following: First, maintain the ideal weight, obesity is an important cause of insulin resistance, in order to avoid the aggravation of insulin resistance should control weight. Pay attention to diet, reduce high-calorie diet and high-sugar diet to avoid increasing the functional burden of pancreatic beta cells and weight gain. Third, pay attention to increase exercise, exercise can not only increase total energy consumption and avoid weight gain, but also enhance insulin sensitivity and improve insulin resistance. Fourth, patients are advised to review their blood glucose regularly to detect possible hyperglycemia as early as possible.
