Sympathetic support of energy expenditure and sympathetic nervous system activity after gastric bypass surgery

Sympathetic support of energy expenditure and sympathetic nervous system activity after gastric bypass surgery

OBJECTIVE This study was designed to determine how gastric bypass affects the sympathetically-mediated component of resting energy expenditure (REE) and muscle sympathetic nerve activity (MSNA). DESIGN AND METHODS We measured REE before and after beta-blockade in seventeen female subjects approximately three years post-gastric bypass surgery and in nineteen female obese individuals for compar...

The Surgery of the Sympathetic Nervous System

Surgery of the Sympathetic Nervous System

This article reviews the innervation of the arterial system of the lower extremity, lumbar sympathectomy in vascular surgery, lumbar sympathectomy for digital gangrene and in the prevention of major amputation of the lower extremity and substance P's role in neurogenic inflammatory modulation. Long-term results of lumbar sympathectomy and direct arterial bypass surgery have also been reviewed. ...

Sympathetic nervous system neuroplasticity.

In human and experimental models of heart failure there is widespread change in the sympathetic nervous system. This involves preferential activation of the sympathetic nervous outflow to the heart, impairment of norepinephrine reuptake by sympathetic nerves, and reduction of the content of norepinephrine in the failing myocardium, attributable in part to sympathetic neuronal rarefaction.1–4 Mi...
