[aldosterone + -ism]
An uncommon cause of hypertension in which the blood contains abnormally high levels of aldosterone. The syndrome results from sodium retention and excretion of potassium by the kidneys. Although it is frequently asymptomatic, patients may occasionally experience frequent urination, nocturia, or headache. If potassium losses are severe, muscular weakness, cramps, tetany, or cardiac arrhythmias may occur.
