What symptom is commonly associated with pheochromocytoma?

Severe hypertension is commonly associated with pheochromocytoma due to the tumor's production of catecholamines, such as epinephrine and norepinephrine. These catecholamines are involved in the body's "fight or flight" response, leading to increased heart rate, constriction of blood vessels, and elevated blood pressure. Patients with pheochromocytoma may experience episodes of paroxysmal hypertension, during which blood pressure can rise significantly and abruptly, often accompanied by symptoms such as headache, palpitations, and sweating.

The characteristic symptoms arise from the sustained stimulation of the cardiovascular system, resulting in persistent or episodic hypertension that can be markedly severe. Managing these hypertensive episodes is crucial in the clinical management of patients diagnosed with pheochromocytoma. Understanding this condition's pathophysiology helps in recognizing related symptoms and guides clinical interventions.
