Si tu energ\u00eda cae sobre todo despu\u00e9s de comer, lee <a href=\"https:\/\/bioprofile.com\/es\/bajon-de-la-tarde-por-que-tu-energia-cae-despues-de-comer\/\">por qu\u00e9 tu energ\u00eda cae despu\u00e9s de comer<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ijzer-de-meeste-studies\">Hierro: la mayor\u00eda de los estudios<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Un estudio sigui\u00f3 a 198 mujeres menstruantes de 18 a 53 a\u00f1os con cansancio sin explicaci\u00f3n. Todas ten\u00edan las reservas de hierro bajas y no hab\u00eda anemia. Durante 12 semanas tomaron cada d\u00eda 80 mg de hierro o un placebo. Con hierro, el cansancio baj\u00f3 un 47,7 por ciento; con el placebo, un 28,8 por ciento. En calidad de vida, depresi\u00f3n o ansiedad, el hierro no supuso ninguna diferencia medible.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">7<\/a><\/sup> Una revisi\u00f3n de seis estudios parecidos encontr\u00f3 el mismo patr\u00f3n. En personas con cansancio y d\u00e9ficit de hierro pero sin anemia, el hierro redujo el cansancio algo m\u00e1s que un placebo.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">1<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que esto significa para ti: si un an\u00e1lisis de sangre muestra poco hierro, tambi\u00e9n sin anemia, tomar hierro extra puede reducir algo tu cansancio. Los grupos de placebo tambi\u00e9n se sintieron mejor, as\u00ed que no todo el cambio se debi\u00f3 al hierro.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Las mujeres en edad f\u00e9rtil tienen m\u00e1s facilidad para quedarse con poco hierro, porque con la menstruaci\u00f3n se pierde sangre. Para este grupo, el Voedingscentrum aconseja 16 mg de hierro al d\u00eda. Para los hombres, y para las mujeres despu\u00e9s de la menopausia, el consejo es de 11 mg. Una carencia real de hierro con anemia casi no se da en los Pa\u00edses Bajos. No se recomiendan suplementos de hierro sin un motivo m\u00e9dico, y solo un an\u00e1lisis de sangre a trav\u00e9s de tu m\u00e9dico de cabecera puede mostrar si tienes una carencia.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">5<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"vitamine-d-een-studie-bij-mensen-met-een-lage-waarde\">Vitamina D: un estudio en personas con un nivel bajo<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">En un estudio doble ciego, 120 adultos cansados pero por lo dem\u00e1s sanos y con poca vitamina D recibieron una sola dosis de 100.000 unidades de vitamina D3 o un placebo. La edad media era de 29 a\u00f1os. Cuatro semanas despu\u00e9s, el 72 por ciento del grupo de la vitamina D se sent\u00eda menos cansado. En el grupo del placebo, fue el 50 por ciento.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que esto significa para ti: en personas que ten\u00edan cansancio y poca vitamina D, una dosis marc\u00f3 una diferencia notable en menos de un mes. Fue un \u00fanico estudio, y no dice nada sobre personas con un nivel normal de vitamina D.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aparte del cansancio, el Voedingscentrum aconseja a varios grupos tomar 10 microgramos extra de vitamina D al d\u00eda. Son los ni\u00f1os hasta 3 a\u00f1os, las mujeres de 50 a 69 a\u00f1os y las personas de 4 a 69 a\u00f1os con la piel oscura o que apenas toman el sol. A toda persona de 70 a\u00f1os o m\u00e1s se le aconseja tomar 20 microgramos al d\u00eda.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">8<\/a><\/sup><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"vitamine-b12-belangrijk-als-je-een-tekort-hebt\">Vitamina B12: importante si tienes una carencia<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Si tomas poca B12, a menudo pasan unos meses o incluso un a\u00f1o hasta que lo notas. Tres grupos corren m\u00e1s riesgo: las personas que no comen productos de origen animal, las personas cuyo cuerpo absorbe mal la B12 y los adultos mayores. A las personas veganas se les aconseja tomar un suplemento de 2,8 microgramos al d\u00eda.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">6<\/a><\/sup> Nadie sabe si tomar m\u00e1s B12 ayuda con el cansancio cuando no tienes un d\u00e9ficit. Una revisi\u00f3n de 16 estudios encontr\u00f3 solo uno que midiera el cansancio sin explicaci\u00f3n, y eso es demasiado poco para sacar una conclusi\u00f3n.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">3<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En palabras sencillas: la B12 importa si tienes un d\u00e9ficit. Si no tienes d\u00e9ficit, no hay pruebas de que un suplemento de B12 te d\u00e9 m\u00e1s energ\u00eda.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"vermoeidheid-bij-de-ziekte-van-crohn\">Cansancio en la enfermedad de Crohn<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">De las personas adultas con enfermedad de Crohn o colitis ulcerosa, el 47 por ciento vive con cansancio. Sube hasta el 72 por ciento cuando la enfermedad est\u00e1 activa, y en remisi\u00f3n sigue siendo el 47 por ciento. Los factores con la relaci\u00f3n m\u00e1s fuerte con el cansancio fueron el sue\u00f1o alterado, la ansiedad, la depresi\u00f3n y la anemia.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">9<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que esto significa para ti: en la enfermedad de Crohn el cansancio es frecuente, tambi\u00e9n en remisi\u00f3n. El sue\u00f1o, el estado de \u00e1nimo y la anemia son los puntos que conviene hablar con tu m\u00e9dico.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"wanneer-je-naar-de-huisarts-gaat\">Cu\u00e1ndo acudir al m\u00e9dico de cabecera<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Contacta con tu m\u00e9dico de cabecera si el cansancio dura m\u00e1s de un mes.

Un cuestionario no puede medir valores en sangre como el hierro, la vitamina D o la B12, y no puede encontrar la causa de tu cansancio. Buscar la causa es tarea de un m\u00e9dico.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"samengevat\">En resumen<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">El cansancio tiene muchas causas, y una carencia es solo una de ellas.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">4<\/a><\/sup> Sobre el hierro es donde m\u00e1s estudios se han hecho, y el hierro ayuda algo a las personas con cansancio y carencia de hierro.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">1<\/a><\/sup> En un estudio, la vitamina D marc\u00f3 la diferencia en personas con un nivel bajo.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">2<\/a><\/sup> Sobre la B12 y el cansancio hay demasiado poca investigaci\u00f3n para poder decir algo.\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">3<\/a><\/sup> Un an\u00e1lisis de sangre a trav\u00e9s de tu m\u00e9dico de cabecera muestra si tienes poco hierro,\u2060<sup class=\"bp-blog-sup\"><a href=\"#bronnen\">5<\/a><\/sup> y el esc\u00e1ner de energ\u00eda muestra cu\u00e1nto cansancio llevas encima hoy.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-blog-sec bp-blog-cta is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\">Mide d\u00f3nde empiezas<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cinco preguntas sobre las dos \u00faltimas semanas, unos tres minutos, y tu puntuaci\u00f3n de energ\u00eda est\u00e1 en tu dashboard.
