ABSTRACT
Primary aldosteronism is a disease characterized by autonomous excess production
of aldosterone, which results in the suppression of renin levels, often causing hypertension
and hypokalemia. Primary hyperaldosteronism is more common than previously thought. The
high prevalence causes damage to the cardiovascular system and kidneys, and the fact that a
diagnosis and treatment can correct the hypertension and hypokalemia justifies the search of
primary hyperaldosteronism in many patients with hypertension. When primary aldosteronism is
suspected, screening tests should be performed; the recommended test is the aldosterone to
renin ratio. Subsequently, the diagnosis should be confirmed by any of the available methods,
such as the oral sodium loading test and saline infusion test, among others. After confirming the
diagnosis, the next step is to determine the subtype of primary aldosteronism, which is important
in determining the most appropriate treatment. Finally, imaging studies should be carried out to
identify possible lesions in the adrenal glands.
