The adrenal glands secrete hormones and other substances to maintain the normal state of the human body, and the growth of tumors in the adrenal glands may change the body's functions and often lead to high blood pressure, which may be related to the following factors.
First, adrenal tumors may secrete too much aldosterone, a hormone that regulates electrolyte balance, and when too much, can lead to sodium and water retention, which increases blood volume and thus blood pressure.
Second, adrenal tumors may also secrete too much cortisol, a hormone that regulates blood pressure, and when too much, can cause blood pressure to rise. In addition, cortisol can also lead to increased reabsorption of salt and water, which in turn leads to an increase in blood pressure.
Third, adrenal tumors can also cause the adrenal glands to secrete too much adrenaline and norepinephrine, which can stimulate the heart and increase the heart rate, while also constricting blood vessels, leading to an increase in blood pressure.
Finally, adrenal tumors can also compress or infiltrate surrounding tissues, causing blood pressure to rise. For example, an adrenal gland tumor may compress the kidneys or surrounding blood vessels, causing impaired kidney function or narrowing of blood vessels, which can cause high blood pressure.
Patients with adrenal tumors need to pay close attention to changes in blood pressure and take timely measures to control blood pressure.
