[Fat control--an effective antihypertensive strategy. Special recommendations for therapy of the overweight patient].

Some 44% of all patients with elevated blood pressure are overweight. In obesity-related hypertension, sympathicotonia is regularly found, together with elevated intracellular calcium, sodium retention, increased cardiac output (per minute) and a sensitivity to salt. The role played by hyperinsulinemia has apparently been overstated. A primary rise in the minimal vascular resistance suffices to reduce the perfusion of the skeletal musculature and, solely on this basis, to induce insulin resistance. For the treatment of obesity-related hypertension, non-medicinal approaches to weight reduction predominate. Reducing the daily salt intake to 5 g can also bring about a measurable reduction in blood pressure. For the treatment with antihypertensive drugs, beta blockers and diuretics are the initial choice; in the case of pronounced metabolic syndrome, ACE-inhibitors and alpha-1 receptors.
