[Rational therapy of Type II diabetes].
Noninsulin-dependent diabetes mellitus is a genetically determined form of diabetes, due to impaired insulin secretion by the B-cells as well as to insulin resistance of the peripheral tissues. According to the glucose toxicity theory hyperglycemia and hyperinsulinemia exist in a vicious circle. Therefore, it is a major therapeutical aim to put the B-cell to rest and improve insulin sensitivity by a strict control of fasting blood glucose and of postprandial hyperglycemia. Furthermore, associated abnormalities within the metabolic syndrome, such as hypertension, dyslipoproteinemia and hemostatic disorders should be corrected to avoid vessel complications. Therefore, it should be started with basic measures as body weight reduction, carbohydrate-rich and fat-poor diet and exercise. If these measures fail to achieve acceptable glycemic control, antihyperglycemic drugs (acarbose, metformin) are indicated, eventually in a combination with small doses of short-acting sulfonylureas. Further impairment of insulin secretion is the indication for sulfonylurea and/or insulin application. HbA1c of 7 to 7.5% should be the goal of antidiabetic therapy, also for patients in advanced age. The main criterion for the choice of antidiabetics is the present insulin secretion capacity. Simple indicators in this respect are changes of body weight, plasma triglycerides and C-Peptide after i.v. glucagon stimulation. Application of insulin in combination with other antidiabetics or in the form of intensified insulin therapy should not be too much postponed.
