The association between obesity and hypertension is well known. The hemodynamic features of obesity-related hypertension are an expansion of extracellular volume inducing hypervolaemia and increased cardiac output, with activation of both the sympathetic nervous system and the renin--angiotensin system. It is suggested that obesity-related hypertension may be considered as a subset of essential hypertension, and treated as an identity. Orlistat and sibutramine both reduce body weight in the obese patients. The use of orlistat in obese hypertensive patients is associated with a small decrease in blood pressure, whereas sibutramine may increase the blood pressure. Thus, orlistat may be preferred in the obese hypertensive patients. Diuretics and beta-blockers decrease insulin sensitivity, which is an unwanted effect in obesity, and should be used with caution in obese hypertensive patients. The calcium channel blockers have no or minor effects on insulin sensitivity and may be considered for use in obese hypertensive patients. Inhibitors of the effects of angiotensin may be the antihypertensive drugs of choice for obese hypertensive patients, as in addition to reducing blood pressure, ACE inhibitors and AT(1) receptor antagonists have no effect or improve insulin sensitivity, and are renoprotective. More clinical trials are needed for the centrally acting antihypertensives (clonidine, rilmenidine) in obese hypertensive patients, as they inhibit the sympathetic nervous and renin--angiotensin systems, which are overactive in this population.

There is a 50 % prevalence of obesity with arterial hypertension. This ratio can increase up to 80 %, depending on body mass index. Important pathogenetic origins are quantity of visceral body fat along with the activation of neuroendocrineum (sympathicus, renin-angiotensin system), an induction of insulin resistance with hyperinsulinemia, and a direct compression of the medulla by fat deposits in the kidneys, which results in hemodynamic changes and an increase in blood pressure. The primary aim is a reduction in weight by means of a balanced diet and life style modification, which can be augmented by weight reducing medication. Orlistat lowers blood pressure and body weight simultaneously, whereas sibutramine accomplishes this only under certain circumstances. Interestingly, blood pressure increases again over the course of 10 years following weight reducing surgical procedures, despite ongoing weight loss. Antihypertensive differential therapy should be focused on pathophysiology and concomitant and target organ disease. Thus ACE inhibitors (alternatively angiotensin receptor blockers), in combination with low dose diuretics, should be preferentially administered, followed by calcium antagonists. Beta blockers should be used if definite cardiac indications are present.
