Signs & Symptons of Pheo Para

The most common sign of Pheochromocytoma and Paraganglioma is uncontrolled elevated hypertension.

Signs and symptoms may occur weekly, several times daily, or once every few months. Most attacks last less than an hour, but rarely more than several days. Attacks may be induced by postural changes, anxiety, trauma, pain, use of medications (histamine, glucagon, tyramine, phenothiazine, metoclopramide, adrenocorticotropic hormone, pseudoephedrine), certain medical procedures (intubation, anesthesia, endoscopy, catheterization), treatment (chemotherapy), and urination or bladder distention (with bladder tumors).
