Excessive sympathetic activity contributes to the pathogenesis of hypertension and the progression of the related organ damage. Adipose afferent reflex ( AAR ) is a sympatho‐excitatory reflex that the afferent activity from white adipose tissue ( WAT ) increases sympathetic outflow and blood pressure. Hypothalamic paraventricular nucleus ( PVN or PVH ) is one of the central sites in the control of the AAR , and ionotropic glutamate receptors in the nucleus mediate the AAR . The AAR is enhanced in obesity and obesity hypertension. Enhanced WAT afferent activity and AAR contribute to the excessive sympathetic activation and hypertension in obesity. Blockage of the AAR attenuates the excessive sympathetic activity and hypertension. Leptin may be one of sensors in the WAT for the AAR , and is involved in the enhanced AAR in obesity and hypertension. This review focuses on the neuroanatomical basis and physiological functions of the AAR , and the important role of the enhanced AAR in the pathogenesis of obesity hypertension.
