OBSESIÓN ALIMENTICIA
obsesión alimenticia.
Introducción: La palabra obsesión proviene del término latino obsessĭo (“asedio”). Se trata de una perturbación anímica producida por una idea fija, que con tenaz persistencia asalta la mente.
Este pensamiento, sentimiento o tendencia aparece en desacuerdo con el pensamiento consciente de la persona, pero persiste más allá de los esfuerzos por librarse de él.
La obsesión tiene un carácter compulsivo y termina por adquirir una condición penosa y angustiante para quien la sufre.
Cuando las obsesiones y las compulsiones se han hecho crónicas, se habla de una neurosis que perturba la vida normal del sujeto y que se transforma en un trastorno obsesivo-compulsivo.
Existen distintos tipos de obsesiones:
Por ejemplo, pueden mencionarse aquellas relacionadas con la alimentación. En estos casos, la obsesión funciona como una barrera psicológica que no permite modificar el peso de una persona en forma saludable. La obsesión en la alimentación puede derivar en enfermedades como la bulimia y la anorexia.
bulimia: La bulimia es una enfermedad de causas diversas (psicológicas y
somáticas), que produce desarreglos en la ingesta de alimentos con periodos de compulsión para comer con otros de dietas abusivas, asociado a vómitos y la ingesta de diversos medicamentos (laxantes y diuréticos).
Es una enfermedad que aparece más en las mujeres que en hombres, aparece en la adolescencia, y dura muchos años.
Las causas son muy diversas, pero la principal causa es el estado psicológico del paciente.
anorexia: La anorexia o anorexia nerviosa es, junto con la bulimia, uno de los principales trastronos alimenticios, también llamados Trastornos psicogénicos de la Alimentación (TFA). Lo que distingue a la anorexia nerviosa es el rechazo de la comida por parte del enfermo y el miedo obsesivo a engordar, que puede conducirle a un estado de inanición; es decir, una situación de gran debilidad ocasionada por una ingesta insuficiente de nutrientes esenciales. En casos graves puede desarrollar desnutrición hambre, amenorrea y extenuación. Sus orígenes nostológicos son muy antiguos, se conocen casos descritos desde la Edad Media. Participan en su evolución las funciones psicológicas, los trastornos neuroendocrinos, hormonales y metabólicos.Los posibles tratamientos están todavía en estudio, los tratamientos farmacológicos actuales pueden dar sólo un modesto beneficio al paciente.
