Low hemoglobin concentration due to either decrease erythrocyte (hence decrease hematocrit) or increase plasma volume.

* Normal range varies depend on the hospital, countryCauses
- Decrease Erythrocytes production (Myelodysplasia; Deficiency of Iron, Vitamin B12, Folate; Thalassemias )
- Blood loss (Surgery, injuries, GIT causes & intestinal worms, Cancers, and menstruation)
- Destruction of Erythrocytes (Hemolysis)
- Hypervolemia
Common anemic symptoms
- Fatigue ( tiredness or weakness )
- Malaise
- Dyspnea
- Irregular heartbeats, palpitations
- Headache
- Dizziness
- Anorexia (loss of appetite)
