Anemias

Introduction

Anemia is an abnormally low number of circulating erythrocytes leading to low hemoglobin levels in peripheral blood (less than 130 g/l in men or 120 g/l in women).

The classification of anemias is complex and since it is a part of hematology, this text will focus on basic types of anemias and the morphological changes they cause in the bone marrow.

Clinical signs

fatigue
dyspnea
tachycardia with palpitations
pale skin
neurologic symptoms (dizziness, faintness, headache)
other

Classification

Anemia resulting from an increased peripheral blood loss
- acute posthemorrhagic anemia
- chronic posthemorrhagic anemia
Anemia resulting from a decreased erythrocyte production
- megaloblastic anemia
- sideropenic anemia
- myelodysplastic syndrome
- aplastic anamia
- anemia caused by hematopoietic depression
- chronic kidney disease anemia
- anemias of chronic disorders
Anemia resulting from an increased erythrocyte destruction
- hemolytic anemia
