Mapeo del Ciclo Menstrual Durante el Uso de la Administración de Insulina en Circuito Cerrado (MCM-Loop)
Cartografía del Ciclo Menstrual Durante el Uso de la Administración de Insulina en Bucle Cerrado
La hipótesis es que la ciclicidad menstrual afecta al metabolismo de la glucosa y de la energía en mujeres con diabetes tipo 1. La base de la hipótesis sobre los efectos del ciclo se fundamenta en la suposición de que las fluctuaciones de las hormonas sexuales femeninas a lo largo del ciclo menstrual provocan cambios en los parámetros fisiológicos del metabolismo de la glucosa y de la homeostasis energética y/o en aspectos del estilo de vida relacionados con la regulación de la glucosa en sangre y el peso corporal. Se espera que las fluctuaciones hormonales afecten a la sensibilidad a la insulina, el vaciado gástrico, el comportamiento alimentario y el gasto energético. Se prevé que la sensibilidad a la insulina sea máxima en la fase preovulatoria y mínima en la fase lútea media. Además, se espera que el vaciado gástrico alcance su punto máximo en la fase folicular, y que el gasto energético y la ingesta dietética sean mayores durante la fase lútea media.
El objetivo principal de este estudio es caracterizar el metabolismo de la glucosa y de la energía a lo largo del ciclo menstrual en mujeres con diabetes tipo 1 que tienen ciclos naturales. Otros objetivos son evaluar el impacto del ciclo menstrual en el control de la glucosa y los requerimientos de insulina, investigar cómo las fluctuaciones en los niveles de hormonas sexuales influyen en el metabolismo de la glucosa y de la energía, y cuantificar tanto la variabilidad interindividual como intraindividual en los cambios metabólicos relacionados con el ciclo menstrual. Además, el estudio evaluará si los cambios en los componentes fisiológicos clave del metabolismo de la glucosa y los factores conductuales median en las variaciones relacionadas con el ciclo menstrual en el control de la glucosa y los requerimientos de insulina.
