Posthemorrhagic Anemia

  • Can be acute or chronic
  • Acute posthemorrhagic anemia is normochromic and normocytic in the first hours after bleeding
  • Restoration of plasma volume after acute blood loss causes temporary dilution of blood and decrease in hematocrit
  • First sign of regeneration of red blood cells is reticulocytosis, which indicates activity of hemopoiesis

Chronic Posthemorrhagic Anemia

  • Occurs with chronic hemorrhage and may be a symptom of gynecological, oncological, or gastrointestinal diseases
  • Characterized by hypochromia, microcytosis, foci of regeneration in bone marrow of tubular bones, and presence of foci of extra-oesophageal hemopoiesis
  • Changes caused by chronic hypoxia are also present

Hemolytic Anemia

  • Characterized by shortening of life of red blood cells
