Rinitis alérgica

La rinitis alérgica o fiebre del heno es un grupo de síntomas predominantemente en la nariz y los ojos, como respuesta a los alergenos como el polvo, caspa y polen. El sistema inmunológico sensibilizado produce anticuerpos a estos alergenos, lo que provoca la liberación de químicos denominados histaminas dentro del torrente sanguíneo. Esto causa salpullido, inflamación del tejido afectado, producción de moco, urticaria, erupciones y otros síntomas. La severidad de los síntomas varía de persona a persona.Rinitis alérgica
