\nBende kans\u0131zl\u0131k var.

Halbuki arkada\u015f\u0131m\u0131n kans\u0131zl\u0131\u011f\u0131 demir ile d\u00fczelmi\u015fti. Bunun \u00fczerine ara\u015ft\u0131rmalar yap\u0131ld\u0131.

Yan\u0131t
\nKanda bulunan alyuvarlar dokulara oksijen ta\u015f\u0131yarak ya\u015fam\u0131n devam\u0131n\u0131 sa\u011flarlar. Alyuvarlar bu g\u00f6revi i\u00e7lerinde bulunan ve kana k\u0131rm\u0131z\u0131 rengini veren \u201chemoglobin\u201d maddesi arac\u0131l\u0131\u011f\u0131yla yaparlar. Hemoglobinin eksikli\u011fi kendisini anemi yani kans\u0131zl\u0131k olarak g\u00f6sterir. Anemi diyebilmek i\u00e7in alyuvar say\u0131s\u0131ndan \u00e7ok hemoglobin miktar\u0131n\u0131n azalmas\u0131 kriter olarak al\u0131n\u0131r. Anemi gerek yeti\u015fkinlerde gerekse \u00e7ocuklarda en s\u0131k g\u00f6r\u00fclen kan hastal\u0131\u011f\u0131d\u0131r. Hemoglobinin \u201chem\u201d k\u0131sm\u0131 demir i\u00e7erdi\u011finden, v\u00fccutta demir eksikli\u011fi olan durumlarda kans\u0131zl\u0131k ortaya \u00e7\u0131kar. V\u00fccut bir\u00e7ok ba\u015fka durumda oldu\u011fu gibi burada da tedbirli ve yedekli \u00e7al\u0131\u015ft\u0131\u011f\u0131ndan demirin k\u0131sa s\u00fcreli eksikli\u011fi hemen anemiye yol a\u00e7maz. Kemik ili\u011fi, demirin depoland\u0131\u011f\u0131 yerdir. Buradan alyuvarlara demir transferi sa\u011flan\u0131r. Ancak a\u015f\u0131r\u0131 \u00e2det g\u00f6ren kad\u0131nlarda oldu\u011fu gibi uzun s\u00fcreli demir kayb\u0131, kemik ili\u011fi depolar\u0131n\u0131n bo\u015falmas\u0131na neden olur ve hemoglobin eksikli\u011fine, dolay\u0131s\u0131yla anemiye yol a\u00e7ar.<\/p>\n
Kanda hemoglobinin azalmas\u0131 yaln\u0131zca demir eksikli\u011finde olmaz. \u00d6rne\u011fin t\u00fcbek\u00fcloz, uzun s\u00fcreli infeksiyonlar, kanser gibi kronik hastal\u0131klarda kemik ili\u011fi demir depolar\u0131 doludur. Ancak demirin alyuvarlar taraf\u0131ndan al\u0131m\u0131nda ve kullan\u0131m\u0131nda sorunlar vard\u0131r. Bu durumda da yeteri kadar hemoglobin yap\u0131lamaz ve anemi g\u00f6r\u00fcl\u00fcr. <\/p>\n
B 12 vitamini alyuvar \u00f6nc\u00fc h\u00fccrelerinin metabolizmas\u0131nda gerekli bir maddedir. Eksikli\u011finde alyuvarlar\u0131n \u00f6nc\u00fclleri h\u0131zla y\u0131k\u0131l\u0131r. Sonu\u00e7ta anemi ortaya \u00e7\u0131kar. Buradan da g\u00f6r\u00fcld\u00fc\u011f\u00fc gibi gerek demir eksikli\u011fi gerekse B 12 vitamin eksikli\u011fi farkl\u0131 yollardan hemoglobini azaltmaktad\u0131r. Sonu\u00e7 ayn\u0131 olsa bile tedavi \u00e7ok farkl\u0131 olmak zorundad\u0131r. Kolayca tahmin edilebilece\u011fi gibi anemiyi d\u00fczeltmek i\u00e7in birinde demir vermek gerekirken di\u011ferinde tedavi vitamin B 12 deste\u011fi olmal\u0131d\u0131r. <\/p>\n","protected":false},"excerpt":{"rendered":"
