How to Test for Hyperaldosteronism

Hyperaldosteronism is a disorder of the endocrine system that has a negative impact on blood pressure. The disease is characterized by increased levels of aldosterone, the hormone responsible for regulating blood levels of sodium and potassium. This means that salt and potassium are retained in the body in unsafe amounts, resulting in elevated blood pressure or, more specifically, hypertension. If you believe you may be affected by this disorder, then you should learn how to test for hyperaldosteronism.

Learn How to Test for Hyperaldosteronism

• 1

  Hyperaldosteronism may be primary or secondary, depending on the cause of excess aldosterone production. For instance, primary hyperaldosteronism is caused by an adenoma (tumor) of the adrenal glands. Secondary hyperaldosteronism may be caused by excess release of renin from the kidneys. Renin is an enzyme which stimulates aldosterone production.

• 2

  The symptoms of hyperaldosteronism can mimic those of other diseases, such as diabetes. Common symptoms include frequent urination, excessive thirst and fatigue. However, some patients will not exhibit any symptoms other than elevated blood pressure.

• 3

  Be prepared to stop taking any blood pressure medications you may have been prescribed if your doctor so orders. The reason for this is that some medications may interfere with the results as you test for hyperaldosteronism.

• 4

  Expect to have blood and urine tests to screen for hyperaldosteronism by measuring aldosterone levels, or potassium levels. Renin secretion may also be checked, which requires that you first lie down flat for 30 minutes. These tests will help to confirm a diagnosis of hyperaldosteronism and help determine if it's a case of primary or secondary hyperaldosteronism.

• 5

  A computed tomography scan (CT scan) may be ordered if a tumor is suspected. If there is a tumor, it may indicate primary hyperaldosteronism.

• 6

  Prepare for more imaging tests, including an MRI, to check for tumors of the adrenal glands.
