Conn's Syndrome, also known as primary hyperaldosteronism, is caused by an overproduction of the hormone aldosterone. This medical condition results in high blood pressure and low potassium levels in the blood. Some synonyms for Conn's Syndrome include hyperaldosteronism, adrenal aldosteronism, and aldosterone excess. This condition is often mistaken for other medical ailments such as anxiety, asthma, and heart failure. Diagnosis of Conn's Syndrome requires medical tests such as blood tests and imaging scans to determine the underlying cause of the high blood pressure. Treatment for Conn's Syndrome includes medications that regulate the hormone levels, and in severe cases, surgical removal of the adrenal gland may be necessary.
