Hyperaldosteronism - primary and secondary

Conn syndrome

Last reviewed: July 26, 2011.

Primary and secondary hyperaldosteronism are conditions in which the adrenal gland releases too much of the hormone aldosterone.

Causes, incidence, and risk factors

People with primary hyperaldosteronism have a problem with the adrenal gland that causes it to release too much aldosterone.

In secondary hyperaldosteronism, the excess aldosterone is caused by something outside the adrenal gland that mimics the primary condition.

Primary hyperaldosteronism used to be considered a rare condition, but some experts believe that it may be the cause of high blood pressure in some patients. Most cases of primary hyperaldosteronism are caused by a noncancerous (benign) tumor of the adrenal gland. The condition is most common in people ages 30 - 50.

Secondary hyperaldosteronism is usually due to high blood pressure. It is also related to disorders such as:

Signs and tests

Sometimes the health care provider needs to insert a catheter into the veins of the adrenal glands to determine which of the adrenals contains the growth.

This disease may also affect the results of the following tests:

Treatment

Primary hyperaldosteronism caused by a tumor is usually treated with surgery. Removing adrenal tumors may control the symptoms. Even after surgery, some people still have high blood pressure and need to take medication. However, they can often reduce the number of medications or doses they take.

Watching how much salt you eat and taking medication may control the symptoms without surgery. Medications used to treat hyperaldosteronism include:

Medicines and diet (but not surgery) are used to treat secondary hyperaldosteronism.

Expectations (prognosis)

The outlook for primary hyperaldosteronism is good with early diagnosis and treatment.

The outlook for secondary hyperaldosteronism depends on the cause of the condition.

Complications

Impotence and gynecomastia (enlarged breasts in men) may occur with long-term spironolactone treatment in men, but this is uncommon.

Calling your health care provider

Call for an appointment with your health care provider if you develop symptoms of hyperaldosteronism.
