Excess catecholamines cause a decrease in the total blood volume, making a patient vulnerable to hypotension during the operation. [121] Therefore, a high-sodium diet with adequate fluid intake should be encouraged prior to surgery. [ 122 ]
Pheochromocytoma (most common), a catecholamine-secreting tumor of the adrenal medulla. [1] [5] Pheochromocytomas may generate sudden bursts of paroxysmal symptoms due to excess catecholamine secretion. In a classical presentation of these tumors, some symptoms that commonly occur are palpitations, sweating, and headaches; these last a variable ...
Adrenal cancer is the presence of malignant adrenal tumors, and includes neuroblastoma, adrenocortical carcinoma and some adrenal pheochromocytomas. Most adrenal pheochromocytomas and all adrenocortical adenomas are benign tumors, which do not metastasize or invade nearby tissues, but may cause significant health problems by unbalancing hormones.

Compare these effects to those seen in Conn's disease, an adrenocortical tumor which causes excess release of aldosterone, [52] that leads to hypertension. [53] [54] [55] Another adrenal related cause is Cushing's syndrome which is a disorder caused by high levels of cortisol. Cortisol is a hormone secreted by the cortex of the adrenal glands.
“When systemic and chronic inflammation accompanies these underlying diseases, it can affect multiple organ systems, manifesting as fatigue, muscle weakness, digestive disturbances, joint pain ...
Serotonin syndrome, in which an excess of serotonin in the synapses causes a similar crisis of hypertension and mental confusion, could be confused with an adrenergic storm. Serotonin, being a tryptamine (non-catecholamine) involved in higher brain functions, can cause dangerous hypertension and tachycardia from its effects on the sympathetic ...
Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the ventral tegmental area and the substantia nigra, the latter of which contains neuromelanin ...
