Debilidad - Overview

Nombres alternativos

Falta de fuerza; Debilidad muscular

Definición:

Es la reducción de la fuerza en uno o más músculos.

Consideraciones:

La debilidad puede ser generalizada (debilidad corporal total) o localizada sólo en un área, lado del cuerpo, extremidad o músculo. La debilidad es más notoria cuando es localizada, en cuyo caso puede desarrollarse después de un accidente cerebrovascular, una exacerbación de una esclerosis múltiple o una lesión a un nervio.

La debilidad puede ser subjetiva u objetiva:

  • Subjetiva significa que usted se siente débil, pero no hay una pérdida mesurable de fuerza. Por ejemplo, usted se puede sentir débil si tiene enfermedades infecciosas como la mononucleosis y la gripe.
  • Objetiva significa que hay una pérdida mesurable de fuerza que se nota durante un examen físico.

Causas:

La debilidad mensurable puede resultar de una variedad de afecciones metabólicas, neurológicas, enfermedades musculares primarias y trastornos tóxicos.
