What causes tumors on adrenal glands?
A pheochromocytoma is a tumor in the adrenal gland. It causes the gland to make too much of the hormones epinephrine and norepinephrine. This tumor often occurs when you are in your 30s, 40s, or 50s. It happens to both men and women.
What is metanephrine in urine?
Metanephrines are made when your body breaks down hormones called catecholamines. These hormones are made by the adrenal glands. Catecholamines help your body respond to stress. They are sometimes called “fight or flight” hormones. They also include epinephrine, norepinephrine, and dopamine.
What medications increase metanephrines?
Plasma metanephrines may be slightly elevated due to withdrawal from benzodiazepines, alcohol and clonidine. Certain anesthetics, cocaine and cardiac antiarrhythmics such as lidocaine can elevate plasma metanephrines. Catecholamines increase in response to acute stress or discomfort.
