Pheochromocytoma patients why blood pressure will fluctuate high and low

Pheochromocytoma

is a neuroendocrine tumor, which produces catecholamines such as adrenaline and norepinephrine, which can promote vasoconstriction and increase blood pressure. After pheochromocytoma stops releasing catecholamines, blood vessels gradually dilate, resulting in a decrease in blood pressure. When

pheochromocytoma causes blood pressure to fluctuate, surgery should be carried out as soon as possible to reduce the impact of the tumor on the body.
