Definición:

Es el agrandamiento de órganos, piel u otras partes del cuerpo, causado por la acumulación de líquidos en los tejidos. La presencia de líquido extra puede llevar a un aumento rápido de peso durante un período corto (de días a semanas).

Consideraciones generales:

La hinchazón (edema) ligera de la parte inferior de las piernas es común en los meses cálidos del verano, en especial si una persona ha estado de pie o caminando mucho.

La hinchazón generalizada o edema masivo (también denominado anasarca) es un signo común en las personas que están muy enfermas. Aunque el edema leve puede ser difícil de detectar, una cantidad grande de hinchazón es bastante obvia.

El edema se describe como edema con o sin fóvea:

  • El edema con fóvea deja una abolladura en la piel después de que uno presiona el área con un dedo durante 5 segundos y luego la abolladura se llena de nuevo lentamente.
  • El edema sin fóvea no deja este tipo de abolladura al presionar en el área de la hinchazón.

Causas comunes:
