Why does lead poisoning cause anemia?

Hematological Toxicity Anemia may develop with lead poisoning due to impaired synthesis of heme, hemolysis of red cells and shortened red cell survival. Anemia is usually mild and is more commonly seen in adults.

What type of anemia is caused by lead poisoning?

Lead toxicity causes a hypochromic microcytic anemia and basophilic stippling of red blood cells. Hypochromia and microcytosis are typically seen in iron-deficiency anemia, which often coexists with lead toxicity.

How lead poisoning causes Microcytic Hypochromic anemia and fatigue?

The anemia most often found is a microcytic, hypochromic anemia, but this is likely due to other causes such as iron deficiency. The mechanism of the ring sideroblasts is related to the accumulation of iron-laden mitochondria in the red blood cell precursors due to the inhibition of ferrochelatase by lead.
