Hemorroides - Overview

Nombres alternativos

Tumor en el recto; Almorranas; Tumor rectal

Definición:

Son venas hinchadas y dolorosas en la porción baja del recto o del ano.

Causas:

Las hemorroides son muy comunes, especialmente durante el embarazo y después del parto. Éstas resultan del aumento de la presión en las venas del ano. Dicha presión provoca que las venas se hinchen, haciendo que duelan, particularmente cuando usted está sentada.

La causa más común es el esfuerzo durante la defecación.

Las hemorroides pueden ser causadas por:

  • Esfuerzo durante las deposiciones.
  • Estreñimiento.
  • Sentarse durante períodos de tiempo prolongados.
  • Infecciones anales.
  • Ciertas enfermedades, como la cirrosis hepática.

Las hemorroides pueden estar dentro o por fuera del cuerpo:

  • Las hemorroides internas se presentan justo dentro del ano, donde comienza el recto.
  • Las hemorroides externas ocurren en el orificio anal y pueden colgar por fuera del ano.
