◦Codes for an abnormal hemoglobin called hemoglobin S (HbS)
◦This defect causes RBCs to become sickle-shaped in low oxygen situations

According to WHO,most common nutrient deficiency in world.
◦A secondary result of hemorrhagic anemia
◦Inadequate intake of iron-containing foods
◦Impaired iron absorption
Iron deficiency anemia

Deficiency of vitamin B12
Lack of intrinsic factor needed for absorption of B12
Treatment is intramuscular injection of B12

ANAEMIA: Preventable, Yet a Problem!!

Management Options
Treat the cause before conception balanced diet, education and
health support. Build up iron stores during
adolescent phase

Oral Iron Therapy Ideal dose – 100mg per day (prophylactic)Ferrous gluconate, ferrous fumarate, ferrous
succinate, ferrous sulphate, ferrous ascorbate citrate
Rise in Hb – 0.8 gm / dl / weekSide effects -G I upset most common
![Page 53: Presentation anemia](https://reader038.vdocuments.us/reader038/viewer/2022102316/54580622af79596b478b4f7b/html5/thumbnails/53.jpg)
Increase your intake of iron
Iron from animal sources is more easily absorbed than iron from plant foods.
Vitamin C increases the uptake of iron, so add foods containing vitamin C (eg. orange juice, tomato salad)
Lack of vitamin B12 can contribute to anemia,
intake of foods containing vitamin B12, such as beef, pork, eggs, cheese and milk.
Increase your intake of folate by adding these foods to your diet: green leafy vegetables, Brussels sprouts, broccoli, whole grains

states…
‘transfusion should be prescribed ONLY for conditions for which there is NO OTHER
TREATMENT’
