Aldosterone

Aldosterone belongs to the class of hormones called mineralocorticoids, also produced by the adrenal glands. Aldosterone helps maintain blood pressure and the balance of sodium and potassium in the blood. When aldosterone production falls too low, the body loses too much sodium and retains too much potassium.

The decrease of sodium in the blood can lead to a drop in both blood volume—the amount of fluid in the blood—and blood pressure. Too little sodium in the body also can cause a condition called hyponatremia. Symptoms of hyponatremia include feeling confused and fatigued and having muscle twitches and seizures.

Too much potassium in the body can lead to a condition called hyperkalemia. Hyperkalemia may have no symptoms; however, it can cause irregular heartbeat, nausea, and a slow, weak, or an irregular pulse.
