Overview

Important mechanism of pathogenesis of hypertension in obesity is renin-aldosterone system in adipose tissue. Adrenal cells can be also stimulated to aldosterone secretion by local adrenal fat cells and also by other factors from fat tissue (lipids, endocrine disruptors). Local system renin-aldosteron is active also in other tissues and organs in obesity related hypertension. Feed back is closed by recently investigated fact that aldosteron hypersecretion can cause metabolic syndrome. Between systemic approach to obesity a new phenomenon of organ obesity is coming - adipokines from local fat cells can influence organ and tissue function e.g. in essential hypertension.

Key words:
hypertension - obesity - metabolic syndrom - mineralocorticoids - endocrine disruptors
