If the adrenaline glands are over/under active, will affect blood pressure.


The adrenal cortex (the outer layer of the adrenal glands) secretes numerous hormones. One of those is aldosterone. This hormone inhibits the level of sodium excreted into the urine, maintaining blood volume and blood pressure. If the adrenal glands release an excessive amount of the hormone aldosterone, the kidneys retain salt and water and lose too much potassium, which raises blood pressure.

A pituitary tumor or other factors can cause the adrenal glands to produce too much of the hormone cortisol which can raise blood pressure.

Some rare tumors of the adrenal gland can cause increases production of the hormones adrenaline and noradrenaline, which can lead to persistent high blood pressure or marked fluctuations in blood pressure.

So, as you can see there are many ways that the adrenal glands can affect blood pressure.
