Liddle syndrome, also known as Liddle's syndrome or Liddle-Hansky-Poznanski syndrome, is a rare genetic disorder characterized by high blood pressure and low levels of potassium in the blood. This condition is caused by mutations in the genes that control the absorption and excretion of sodium and potassium in the kidneys. Other terms used to describe Liddle syndrome are pseudohyperaldosteronism, hypertension with hypokalemia and alkalosis, and familial hyperaldosteronism type I. However, these terms are less commonly used and Liddle syndrome remains the primary term for this condition. While there is no cure for Liddle syndrome, treatment options include medication to control blood pressure and potassium levels, as well as dietary changes to reduce sodium intake.
