Síndrome de hipoventilación y obesidad (SHO) - Overview

Nombres alternativos

Síndrome de Pickwick

Definición:

Es una afección que se presenta en las personas obesas, en la cual la respiración deficiente lleva a bajos niveles de oxígeno y niveles más altos de dióxido de carbono en la sangre.

Causas:

La causa exacta de este síndrome se desconoce. Se cree que este síndrome resulta tanto de un defecto en el control del cerebro sobre la respiración como del peso excesivo (debido a la obesidad) contra la pared torácica, lo cual le dificulta a la persona tomar respiraciones profundas. Como resultado, la sangre tiene demasiado dióxido de carbono e insuficiente oxígeno. Las personas con este síndrome a menudo están cansadas debido a la pérdida de sueño, sueño de mala calidad y niveles bajos de oxígeno en la sangre (hipoxia) crónicos.

La mayoría de los pacientes con el síndrome tienen una forma de apnea del sueño. La obesidad es el principal factor de riesgo.
