There are two forms of hyperalsosteronism: primary and secondary.  Persons 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 hypertension in some patients.  Most cases of primary hyperaldosteronism are caused by a noncancerous (benign) tumor of the adrenal gland. Secondary hyperaldosteronism is generally related to hypertension. It is also related to disorders such as cirrhosis of the liver, heart failure and nephrotic syndrome.
