Well done job @suesa.This is a good information about ephinephrin.I guess alot of people would have packed up if this hormone ceased to function.But I want to ask a question,is it possible that over secretions may leads to damage of kidney ?

I'd have to look into that, can't give a definite answer right now.
Okay.
steep, oversecretion of epinephrine, a catecholamine, doesn't so much damage the kidney nor adrenal gland, but the target organs being stimulated. A condition called pheochromocytoma mimics the very situation you ask about. Pheo's are collections of abnormal tissue which secrete catecholamines but are not under hypothalamic nor pituitary negative feedback control. Therefore, excess epinephrine like hormone is secreted and in elevated amounts and over prolonged periods. The stresses on the body include damage to the heart and blood vessels. Cardiac arrhythmias (tachyarrhythmias or fast arrhythmias) can develop from the over stimulation, as can high blood pressure, damage to heart muscle, and eventual heart failure. Eventually, if the condition goes into "crisis mode" other organs can fail from the prolonged excessive overstimulation , including the brain, heart, liver and kidneys.
