Type 2 diabetes mellitus is characterized by impaired insulin release and sensitivity, elevated blood sugar and unfavourable changes in blood lipids. Insulin resistance and adverse blood lipids are also seen in the state of essential hypertension (the metabolic syndrome). Patients should learn to measure their own blood sugar. Treatment usually begins with regulation of the diet for 3-6 months. If this treatment fails, the next step is to give oral antidiabetic agents. Insulin treatment is required 1) when blood sugar is excessively high; 2) when oral agents fail; and 3) in case of increased need of insulin due to intercurrent disease. Antihypertensive treatment should not have adverse metabolic effects in patients with type 2 diabetes.
