MSH: Abnormally low potassium concentration in the blood. It may result from potassium loss by renal secretion or by the gastrointestinal route, as by vomiting or diarrhea. It may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities (depression of the T wave and elevation of the U wave), by renal disease, and by gastrointestinal disorders. (Dorland, 27th ed),CSP: abnormally low potassium concentration in the blood; may result from excessive potassium loss by the renal or gastrointestinal route, from decreased intake, or from transcellular shifts; manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities, and by renal and gastrointestinal disorders.,NCI: A disorder characterized by laboratory test results that indicate a low concentration of potassium in the blood.,NCI: Lower than normal levels of potassium in the circulating blood.
