The paper analyzes an update on the etiology, mechanisms, and symptoms of the common clinical and laboratory syndrome associated with a reduction in blood potassium level to ≤3.5 mmol/l. The etiological and pathogenetic classification of hypokalemia has been developed, which reflects a wide range of physiological and pathological conditions accompanied by this dangerous homeostatic disorder. The author details the basic mechanisms of hypokalemia, shows difficulties in clinical and laboratory diagnosis, and specifies ways, means, and methods to overcome the diagnostic difficulties. A scheme/algorithm is proposed to diagnose the main varieties of hypokalemia. Safe approaches to its elimination are discussed.
