Secreción ectópica de hormona antidiurética - Overview

Nombres alternativos

Síndrome de secreción inadecuada de hormona antidiurética (SIHAD); Síndrome de secreción inadecuada de vasopresina

Definición:

La hormona antidiurética (HAD), o vasopresina, es una sustancia producida en forma natural por el hipotálamo y liberada por la hipófisis. Esta hormona controla la cantidad de agua que el cuerpo elimina.

La secreción ectópica de la hormona antidiurética es la liberación de esta hormona desde un lugar anormal dentro del cuerpo. Ectópico significa "fuera de lugar".

Causas:

La causa más común de la secreción ectópica de HAD es el cáncer. Ciertos cánceres pulmonares, al igual que algunos tumores de cabeza y cuello, son los cánceres más comunes que causan este problema. En casos poco frecuentes, muchos otros tumores pueden causar la secreción ectópica de HAD.
