The document provides an overview of anemia, including definitions, causes (such as nutritional deficiencies and chronic diseases), classifications based on RBC morphology and etiology, clinical features, diagnostic methods, and treatment options. It outlines symptoms related to different types of anemia and details on how to diagnose and treat the condition, emphasizing the importance of addressing both the symptoms and underlying causes. The presentation aims to educate the audience on anemia's implications for various demographics and the necessary clinical responses.

5.  Taken from Greek language (an meaning absence
& hemia meaning blood), the term Anemia is use
to describe a reduction in the hemoglobin
concentration or in the number of circulating
RBCs below the level considered normal for the
person's age, sex and locality.

8. Causes Of
Anemia

9.  There are many diseases, conditions and other
factors causes anemia, few of which are:
 Nutritional deficiencies i.e. Iron, vit B12, folate etc.
 Hemolytic disorders e.g. Hypersplenism
 Acute or chronic Blood loss e.g. from G.I Tract,
Hemorrhage
 Bone marrow disorder
 Chronic Diseases e.g. Renal failure, Liver disease and
Malignancies

10. Causes Of Anemia (Cont….)
 Infections and inflammation e.g. Malaria, Cl.
Tetani
 Toxicity (from drugs, metals and poisons)
e.g. Lead Poisoning
 Autoimmune disorders .e.g. SLE,
 Heredity defect e.g. Thalassemia

12. Classification Of Anemia
 Classification of anemia can be made the bases of
 RBCs Morphology
 Etiology

13. Morphological Classification
 In morphological approach anemia is classified by the
size or volume of RBC which is expressed as Mean
Corpuscular or Mean Cell Volume(MCV).
 On the basis of MCV, following are the types of
anemia:
 Microcytic Anemia (MCV<76fl)
 Macrocytic Anemia (MCV >98fl)
 Normocytic Anemia (MCV b/w 76 – 98 fl)

14. Microcytic Anemia
(<76 fL)
Macrocytic Anemia
(>98fL)
Normocytic Anemia
(76-98 fL)
1) Iron Deficiency
anemia
Vit. B12 & folate
deficiency
Vit B2 & B6
2) Thalassemia
Alcoholism
Hemolytic Anemia
3) Sideroblastic Anemia
Acute Blood Loss
Post Hemorrhagic
Anemia
4) Lead Poisoning Anemia
Liver disease
Sickle Cell Anemia
5) Chronic Disease Anemia
Aplastic Anemia
Anemia in Pregnancy

15. Etiological Classification
 Etiological Classification of Anemia include
 Anemia due to impaired RBC production
 Anemia due to excessive destruction
 Anemia due to Blood loss

16. Clinical Features Of Anemia

17. Clinical Manifestations
 The clinical features of Anemia can result from
following factors.
1.
Tissue Hypoxia
2.
Compensatory Mechanism
3.
Rate of blood loss/destruction of RBCs
4. Causes of Anemia

18. Symptoms of Tissue Hypoxia
Largely affect Central Nervous System,
Cardio-vascular system and Muscular
system as their Oxygen requirement is
high than other.

19. Neurological Symptoms:
 Dizziness, fainting, lack of concentration
 Blurred or diminished vision
 Headache, tinnitus, Vertigo
 Paraesthesia in the fingers and toes
 Insomnia, irritability, confusion

20. Cardio Vascular Symptoms
 Dyspnea
 Palpitation
 Angina

at rest (in sever cases)
 Intermittent claudication

 Orthostatic Hypotension
CV Signs includes
 Tachycardia, bounding pulse
 Loud HS with S3 over mitral or tricuspid area
 Systolic murmur
 Raised JVP

21. Musculoskeletal symptoms
 Exercise intolerance

22. Other Features
 Pallor of the skin, sclera and mucous membranes
 Jaundice
 Lymphadenopathy
 Hepatosplenomegally
 Bony Pain
 Petechiae
 Hair Loss
 Anorexia, Weight Loss

23. Compensatory Mechanism
1. Increase Cardiac Output (to maximize O2 delivery to tissue)
 Tachycardia, bounding pulse
2. Increase Erythropoiesis
 Liver and Yellow Bone marrow
3. Increase Plasma Volume
4. Redistribution of blood to more vital organs
 By selective vasoconstriction to non-vital organs

36. Lab Investigations
1) Complete Blood Count:
 Hemoglobin level
 Hematocrit Rate (M:40 – 52%, F: 35 – 46%)
 RBC Count (M: 4.5 – 6.5, F: 4.0 – 5.4 mil/mm3)

 Hemoglobin Electrophoresis

38. Other Lab Investigations
 Bone marrow aspiration
 Liver and Renal Function Test
 Coombs Test
 Vit & mineral deficiencies
 Hormonal Deficiencies

39. How To Treat Anemia

40. Treatment
 Depends on Type, cause and severity
 Goal is to increase Oxygenation to tissue and to treat the
underlying cause
 Certain modes of treatment include:
 Dietary Changes or Supplemental Diet
 Medicine
 Procedures
 Surgical Measurement

41. Treatment
 Dietary Changes & Supplements
 To correct the deficient vitamin or mineral, the low level
causes anemia.
 Diet Rich in Minerals & Vitamins (B12, Vit C, folate)
 Oral or Injectable supplement of these substance
 Medicine including
 Antibiotics / Anti-parasitic for infection or infestation
 Hormones (Erythropoietin, Progesterone and
Androgen)

42. Procedures
 Blood Transfusion
 Usually used to treat severely anemic patients as in
thalassemia major or sickle cell disease or to replace the
blood loss after injuries or surgeries.
 For multiple transfusion, Iron Chelation agent
(Deferasirox) should be given to prevent iron over dose.
 Allogeneic Bone Marrow Transplant
 Surgical Measurement include repair or removal of G.I part
causing blood loss and splenectomy.
