  • Desequilibrios de potasio en el organismo
  • La hipopotasemia es una concentración insuficiente de potasio en el cuerpo.
  • Causas de la hipopotasemia
  • Bajo consumo alimentario de potasio
  • Consumo elevado de sodio
  • Medicamentos que aumentan la excreción de agua, principalmente los diuréticos
  • Los signos y síntomas se relacionan con la función del potasio en las células nerviosas y en la contracción muscular.
  • Debilidad y calambres musculares
  • Dificultad respiratoria
  • Estreñimiento
  • La deficiencia grave de potasio puede causar contracciones cardíacas anormales y ser mortal.
  • La hiperpotasemia es una concentración elevada de potasio en la sangre.
  • La hiperpotasemia suele ser silenciosa y no presenta signos ni síntomas.
  • La disfunción renal suele causar hiperpotasemia.
  • Los niveles extremadamente altos alteran los impulsos eléctricos que estimulan el corazón.
  • La alteración cardíaca puede provocar que el corazón se detenga.

"Insufficient potassium levels in the body, or hypokalemia, can be caused by a low dietary intake of potassium or by high sodium intakes, but more commonly it results from medications that increase water excretion, mainly diuretics. The signs and symptoms of hypokalemia are related to the functions of potassium in nerve cells and consequently skeletal and smooth-muscle contraction. The signs and symptoms include muscle weakness and cramps, respiratory distress, and constipation. Severe potassium depletion can cause the heart to have abnormal contractions and can even be fatal. High levels of potassium in the blood, or hyperkalemia, also affects the heart. It is a silent condition as it often displays no signs or symptoms. Extremely high levels of potassium in the blood disrupt the electrical impulses that stimulate the heart and can cause the heart to stop. Hyperkalemia is usually the result of kidney dysfunction."
