How does spironolactone treat hyperaldosteronism?

Hyperaldosteronism occurs when your body produces too much aldosterone, a hormone that balances sodium and potassium levels in the body. This condition can be caused by a number of factors, including severe high blood pressure, a tumor in the adrenal gland or narrowed blood vessels in the kidneys. Hyperaldosteronism has been known to cause a deficiency of potassium in the body. Spironolactone can treat hyperaldosteronism by blocking the function of aldosterone. As an aldosterone receptor antagonist, spironolactone helps the kidneys better process liquid waste, which then reduces the amount of water your body retains. This can increase potassium levels and prevent complications of hyperaldosteronism.
