To decide anemia
1) RBC less than 4.5
2) Hemoglobin less than 11
3) Size of RBC (macro,normally,microcytic)
NORMAL corpscular Hemoglobin
27-32
Normocytic
78%-98%
Macrocytic
> 100
Microcytic
<100

How does body react to anemia?
Erythropoeitin increases to increase RBC production
Increase cardiac output
Increase plasma volume
Increase in lactic acid
CLINICAL PICTURE OF anemia
FATIGUE
WEAKNESS
increase cardiac output
DYSPNEA
Palpitation
Claudication pain
Signs of anemia
H eart failure but only if Hemoglobin 2 or 3
T achycardia
P allor
Pilonychia
IRON deficiency anemia
JAUNDICE/yellow lemon
HEMOLYTIC ANEMIA
SPHEROCYTOSIS
SPLEENOMEGALY/huge spleen
What increases iron absorption ?
Vitamin C
Decreases iron absorption
TANNIC ACID
MALBSORPTION (DUODENUM/JEJUNUM PROBLEMS)
phytate
IRON stored as
FERRITIN
CAUSES OF iron deficiency anemia
1) Decrease iron intake (malignancy,anorexia,old age)
2)increase iron requirement (pregnancy(hemodilution))
3)decreased absorption of iron(phytate/malabsorption)
For C section Hemoglobin has to be:
10
Most common reason for blood loss in Egypt
Oesophageal varices
Causes of Iron deficiency anemia
*Oesophageal varices (chronic liver disease hepatitis C&D
Bilharizia Chronicity)
*Multipara(bleeding from IUD)
*Intravascular hemolysis( Paroxysmal nocturnal hemoglobinuria)
