Phaeochromocytoma
How the adrenal glands are affected
The adrenal glands produce a range of hormones that are vital for the normal working of the body.
Most phaeochromocytomas develop at the centre of one or both of the adrenal glands, in a part called the adrenal medulla.
The cells of the adrenal medulla make the 'fight or flight' hormones adrenaline and noradrenaline, and release these into the bloodstream when they are needed. These hormones control heart rate, metabolism and blood pressure.
Phaeochromocytomas can cause the adrenal medulla to produce too much of these hormones, which often results in problems suchas Palpitations and high blood pressure .
