Acromegalia - Overview

Nombres alternativos

Adenoma somatotrófico; Exceso de hormona del crecimiento; Gigante hipofisario

Definición:

Es un trastorno metabólico crónico en el cual hay demasiada hormona del crecimiento y los tejidos corporal gradualmente se agrandan.

Causas, incidencia y factores de riesgo:

La acromegalia se presenta en aproximadamente 6 de cada 100.000 adultos y es ocasionada por la producción anormal de hormona del crecimiento después de haberse completado el crecimiento normal del esqueleto y otros órganos.

La producción excesiva de la hormona del crecimiento en los niños produce gigantismo en vez de acromegalia.

La causa del aumento en la liberación de la hormona es, generalmente, un tumor no canceroso (benigno) de la hipófisis. Esta glándula, que se localiza justo debajo del cerebro, controla la producción y liberación de varias hormonas diferentes, incluyendo la hormona del crecimiento.
