Why Do I Not Absorb Iron

Conditions like celiac disease, ulcerative colitis, or Crohn’s disease can make it harder for your intestines to absorb iron. Surgery such as gastric bypass that removes part of your intestines, and medicines used to lower stomach acid can also affect your body’s ability to absorb iron.

What happens if your body can't absorb iron?

Without enough iron, your body can‘t produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath.

What conditions prevent iron absorption?

Mucosal malabsorption occurs in celiac disease, tropical sprue, Crohn’s disease etc. Postmucosal condition arises due to impaired nutrients transport e.g. intestinal lymphangiectasia, macroglobulinemia etc. Disorders of malabsorption lead to decreased iron absorption and produce iron deficiency anemia.
