[Non-insulin therapy in diabetes mellitus].
Changes to nutritional habits, including the reduction of weight, are basic therapy principles for the treatment of diabetes mellitus. With overweight patients a reduction of energy intake is important. Patients with diabetes mellitus should eat plenty of carbohydrates, the intake of fat should be limited to a maximum of 35%. Patients treated with insulin must be made to calculate carbohydrate exchange units. Unless there are contraindications, diabetic patients should be encouraged to engage in physical exercise. Educating the patients is of major importance in the treatment of diabetics; this must be undertaken by trained personnel. All diabetic patients treated with oral antidiabetic drugs or insulin should be encouraged to measure their blood glucose levels themselves, in cases of insulin therapy this is an absolutely necessity. If with the aid of basic therapy measures, which include the control of fasting blood glucose, postprandial blood glucose and HbA1c levels, the aims of the therapy are not reached, this is an indication for the use of oral antidiabetic drugs. The drug should be chosen with the dominant pathophysiological disturbance in mind. In the case of increased fasting blood glucose values (hepatic insulin resistance leading to increased glucose production by the liver), after contraindications have been excluded, the use of metformin is recommended. If there are significantly increased postprandial blood glucose values (due to an early-insulin-secretion deficiency or severe insulin resistance), the use of alpha-glucosidase-inhibitors, metformin, sulphonylureas or glinides is indicated. With obese patients alphaglucosidaseinhibitors and metformin are the drugs of choice, with patients with BMI < 25 kg/m2 these are sulfonylureas or glinides. In cases of severe insulin resistance the use of glitazones in conjunction with metformin or sulphonylureas may be indicated.
