WebWhat is iron deficient erythropoiesis? Latent iron deficiency (LID), also called iron-deficient erythropoiesis, is a medical condition in which there is evidence of iron deficiency without … A feedback loop involving erythropoietin helps regulate the process of erythropoiesis so that, in non-disease states, the production of red blood cells is equal to the destruction of red blood cells and the red blood cell number is sufficient to sustain adequate tissue oxygen levels but not so high as to cause sludging, thrombosis, or stroke. Erythropoietin is produced in the kidney and liver in response to low oxygen levels. In addition, erythropoietin is bound by circulating red blood cell…
WebJan 23, 2024 · Iron is essential for erythropoiesis, and the restriction of iron supply inhibits erythropoiesis. Hepcidin, the principal hormone of iron homeostasis, controls dietary iron absorption and plasma iron concentration. Hepcidin is negatively regulated by the membrane protease TMPRSS6. WebWhen iron intake is chronically low, stores can become depleted, decreasing hemoglobin levels. When iron stores are exhausted, the condition is called iron depletion. Further decreases may be called iron-deficient erythropoiesis and still further decreases produce iron deficiency anemia. Blood loss is the most common cause of iron deficiency.
