Descriptor English: Potassium Deficiency
Descriptor Spanish: Deficiencia de Potasio
Descriptor deficiencia de potasio
Scope note: Cuadro debido a la disminución del aporte de potasio en la dieta, así como a la inanición o a fallos al administrar soluciones intravenosas, o a pérdida gastrointestinal en diarreas, abuso crónico de laxantes, vómitos, aspiración gástrica o divertículos intestinales. Un déficit importante de potasio puede producir debilidad muscular y conducir a parálisis y fallos respiratorios. La disfunción muscular puede dar por resultado hipoventilación, íleo paralítico, hipotensión, contracciones musculares, tetania y rabomiólisis. La nefropatía producida por déficit de potasio deteriora el mecanismo de concentración, produciendo POLIURIA y disminución en la capacidad máxima de concentración urinaria con POLIDIPSIA secundaria.

Scope note: A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing POLYURIA and decreased maximal urinary concentrating ability with secondary POLYDIPSIA. (Merck Manual, 16th ed)
