Blood Physiology :
1
Structure of RBCs :
• RBCs : Red Blood Cells/Erythrocytes are Biconcave
(Concave on both surfaces) in shape
• As they mature, they acquire hemoglobin
RBCs/Erythrocyte
2
Hemoglobin :
• Hemoglobin is iron (in ferrous form) containing
protein in Erythrocytes
Hemoglobin
3
Function of Hemoglobin :
• Hemoglobin combines with Oxygen in lung and is
carried to all tissues throughout body ;
Thus Oxygen is delivered to tissues
• Carbon dioxide which is produced in tissues is carried
back to lungs with help of Hemoglobin
• Thus, Hemoglobin plays a vital role in the transport
of respiratory gases in the body
4
Erythropoesis :
• Erythropoiesis is the process by which red blood cells
(erythrocytes) are produced
• Erythro : Erythrocytes
Poiesis : Formation
5
Life cycle of Erythrocytes :
Life span of RBCs - 120 days
Sequestration (Destruction) of old RBCs
Erythropoiesis
New RBCs
6
7
Erythropoiesis process..
• In process of erythropoiesis, first multiplication of
stem cells and precurssor cells takes place ( goes on
for 10-14 days)
• Followed by iron uptake which goes on for 5-7 days
8
Anemia :
Definition :
It is decreased oxygen carrying capacity of blood
Less than normal (Decreased) Erythrocyte number
and
Less than normal ( Decreased )Amount of hemoglobin
In pregnancy, anemia is diagnosed as lower than 11
gram% Hb
9
Anemia of Pregnancy :
• Pregnancy doubles the amount of iron required by a
woman’s body.
• Extra iron is needed to make hemoglobin for the extra
volume of blood produced during pregnancy and to
provide iron to the developing fetus
• Supply of iron in the body is not sufficient to produce
the required hemoglobin, the result is anemia.
• Hence, iron supplements are recommended from
second trimester of pregnancy

9 out of 10 pregnant women in India are anemic, as
not all patients respond adequately to Iron oral
therapy due to side effects (gastrointestinal
discomfort) of oral iron which lead to poor
compliance and lack of efficacy *

incidences are also rising in India
12
High Risk Pregnancy
• Any of the below…
• Previous pregnancy – with complication (such as
IUGR, preeclampsia)
• Pregnancy at age of 35 years or above
• Pregnancy with more than one baby
• Diabetes, hypertension, asthma
• Abnormalities of reproductive tract, Uterine fibroids13

Benefits of Sustained Release Iron
• In terms of efficacy related to rise in hemoglobin,
sustained release iron is more potent than
conventional iron
• After 12 weeks of treatment, 80 mg elemental iron
given in sustained release form is equivalent to 105
mg elemental iron given in conventional release iron
in terms of hemoglobin rise
• Eur J Nutr. 2012 Mar, 51(2):221-9
24
Benefits of Sustained Release Iron
• Systemic review of 106 studies including data from
10515 patients showed that sustained release ferrous
salt showed 88.29% reduction ( came down to 3.7 %
from 31.6% ) in gastrointestinal adverse effects as
compared to immediate release ferrous salt
• Sustained release ferrous salt is better tolerated than
immediate release ferrous salt
• The Scientific World Journal, 2012;2012:846824
25
Sustained release iron (ferrous ascorbate) is
superior to immediate release
formulations
• More potent Hb rise
• 88 % reduction in GI adverse effects
• Ensures better patient compliance
Eur J Nutr. 2012 Mar, 51(2):221-9
There are two important ingredients
Which play significant role in
Erythropoiesis
LMF ( L Methyl Folate – active form of folic acid )
and
Methylcobalamin
(Acitve form of vitamin B12)
27
• LMF & methylcobalamin help in
- Multiplication of stem cells and precurssor cells
required for erythropoiesis (RBC formation)
* Baillieres Clin Haematol. 1995 Sep;8(3)441-59
** Annual Review of Nutrition.2004 July Vol.24 105-131

Effect of Iodine Supplementation During
Pregnancy on Infant Neurodevelopment
• Iodine is the main constituent of thyroid hormones,
which in turn are required for fetal brain
development
• The Mental Development Index and Psychomotor
Development Index (PDI) for 691 children were
obtained
• Lower intake of iodine led to decrease in
Psychomotor Development Index (PDI)

71
Micronutrients in fetal growth and development
• Minerals are important either as central components
of the catalytic sites of enzymes (Cu and Fe, for
example) or as stabilising factors in enzymes and
transcription factors (Zn, for example)
• Iron deficiency is associated with increased risk of
maternal haemorrhage, and peri-partum blood loss
has more severe consequences for anemic mother
Br Med Bull. 1999;55(3):499-510
72
Micronutrients in fetal growth and development
• Severe copper deficiency causes fetal resorption
while milder deficiencies result in skin, neuronal and
hair abnormalities
• The lesions underlying alterations presumably occur
as a result of reduced cupro-enzyme activity
• Copper deficiencies in collagen and elastin cross
linking, due to a fall in lysyl oxidase activity, lead to
problems with lung development and with aortic
elasticity.
Br Med Bull. 1999;55(3):499-510

Role of Minerals
• Improve fetal birth weight
• Essential for fetal brain development
