Treating hyperaldosteronism focuses on reducing your aldosterone levels or blocking the effects of aldosterone, high blood pressure, and low blood potassium. If you already take medication for high blood pressure, your doctor might ask you to stop taking it for a brief period of time while they do these tests. If blood from each gland has similarly high levels of aldosterone, both glands are likely overactive. If blood from one gland has significantly more aldosterone, you may have a benign tumor on one gland. This involves taking a blood sample directly from the veins of each adrenal gland and testing the amount of aldosterone in it. These imaging tests allow your doctor to check for any tumors on or around your adrenal glands. This is very similar to the salt-loading test, but it includes taking fludrocortisone, an oral steroid that mimics aldosterone. This measures the levels of aldosterone and sodium in your urine after following a high-sodium diet for three to five days. This blood test measures your aldosterone, renin, and other levels after you receive an IV sodium and saline solution. This blood test measures your aldosterone, renin, and other levels after you receive a dose of the medication captopril, an ACE inhibitor. People with hyperaldosteronism generally have low renin levels and high aldosterone levels.ĭepending on the results of your blood test, your doctor might run some other tests, including:
If you have symptoms of hyperaldosteronism, your doctor will likely start by doing a blood test to check your levels of aldosterone and renin, an enzyme released by your kidney that works with aldosterone to help balance blood pressure. a blockage or narrowing of the renal artery.Several things can cause this, including: It’s usually related to reduced blood flow to your kidneys. Secondary hyperaldosteronism is caused by something outside the adrenal glands.
