¿Cuáles son los valores de vitamina D recomendados?
Si quiere conocer los valores recomendados de vitamina D en sangre y que factores puede alterar estos valores diríjase a nuestra guía de: vitamina D en la sangre normal
¿Qué indican los valores de vitamina D altos o elevados en sangre?
Los valores elevados de vitamina D no son frecuentes, pero pueden elevarse en caso de tomar excesiva cantidad de vitamina D o por una exposición elevada a la luz del sol. Sin embargo, en muchas ocasiones se debe a un consumo excesivo o inadecuado de suplementos de vitamina D.
La vitamina D que se suele medir en las pruebas corresponde a la forma 25-hidroxivitamina D (25-OH vitamina D) que es la que circula en mayor cantidad por la sangre.
Los niveles de vitamina D (25-OH vitamina D) en sangre suelen proporcionarse en ng/ml que son sobre los que está basado esta información. Si su análisis especifica otras unidades (por ejemplo, nmol/l) puede convertirlos usando la siguiente herramienta:
Los niveles elevados de vitamina D (25-OH vitamina D) en sangre pueden indicar:
Niveles ligeramente altos (50 - 100 ng/ml en adultos):
Los niveles de vitamina D en la sangre se encuentran por encima de lo normal. La vitamina D se produce por exposición a luz solar por lo que puede aparecer en profesiones muy expuestas al sol como socorristas o sufistas.
Conviene vigilar los niveles en próximos análisis y consultar con su médico si está tomando algún tipo de suplemento vitamínico.
Niveles excesivamente altos (> 100 ng/ml en adultos) :
Los valores de vitamina D en la sangre son muy elevados y conviene reducirlos para evitar graves problemas de salud.
Valores elevados de vitamina D en la sangre pueden producir síntomas como náuseas, debilidad y estreñimiento.
Niveles por encima de 150 ng/ml se consideran tóxicos y pueden producir hipercalcemia (aumento del nivel de calcio en la sangre), hipercalciuria (excreción excesiva de calcio en la orina) y supresión de la hormona paratiroidea con sus problemas correspondientes.
¿Qué puede producir un aumento de los valores de vitamina D en sangre?
Entre las principales causas, que sin ser una enfermedad en sí misma pueden aumentar los niveles de vitamina D en la sangre están:
- Excesiva exposición a luz solar
- Intoxicación por vitamina D
- Medicamentos
- Antiarrítmicos
- Digoxina
- Hormonas sexuales
- Estrógenos
- Tiazidas
- Antiarrítmicos
¿Qué enfermedades pueden producir vitamina D elevada en un análisis?
Los niveles aumentados de vitamina D en la sangre pueden observarse en las siguientes enfermedades:
- Síndrome de Williams
¿Qué puedo hacer para disminuir los valores de vitamina D?
La mayoría de los casos en los que aparece un aumento excesivo de la vitamina D en la sangre se deben a estar tomando suplementos de vitamina D de forma excesiva o inadecuada, por lo que si este es el caso sería conveniente dejar de tomarlos y si su médico lo considera adecuado reducir también el consumo de calcio en la dieta.
¿Qué valores de vitamina D en sangre se consideran altos o elevados?
Se consideran valores altos de vitamina D según la gravedad los que aparecen en la siguiente tabla:
IMPORTANTE: Estos valores medidos en ng/ml son un ejemplo orientativo basado en el prototipo de un adulto de mediana edad (45 años) que no presenta enfermedad conocida, con una exposición adecuada a la luz del sol y que no está tomando ninguna medicación. Estos rangos pueden variar dependiendo de las circunstancias personales de cada paciente y de las prácticas de análisis de cada laboratorio.
