Classification of Anemia

What is the term for the loss of blood by internal or external bleeding over a long period of time?

What is the term for the destruction of red blood cells?

Which type of anemia is caused by a defect within the red blood cells themselves?

What is the term for abnormally heavy bleeding at menstruation in women?

What is the term for a medical condition in which the ability of the blood to clot is severely reduced?

What is the term for a condition where the red blood cells are produced healthy but are later destroyed by external factors?

What is the term for anemia that occurs due to deficiency of a nutritive substance necessary for erythropoiesis?

What is the term for a disease in which the body produces abnormally shaped red blood cells?

What is anemia caused by?

What are the two methods of classifying anemia?

What is the characteristic of Normocytic Normochromic Anemia?

What is the term for excessive loss of blood?

What is the characteristic of Macrocytic Normochromic Anemia?

What is the term for anemia caused by sudden loss of a large quantity of blood?

How long does it take to correct anemia caused by Acute Hemorrhage?

What is the term for anemia caused by a deficiency of nutrients?

Anemia is a deficiency of hemoglobin in the blood, which can be caused by too few red blood cells or too little hemoglobin in the cells.

Anemia can be classified using two methods: morphological classification and etiological classification.

Morphological classification is based on the size and color of red blood cells (RBCs).
There are four types of anemia classified by morphological classification:
- Normocytic Normochromic Anemia: RBCs are normal in size and color, but their number is less.
- Macrocytic Normochromic Anemia: RBCs are larger in size with normal color, but their number is less.
- Macrocytic Hypochromic Anemia: RBCs are larger in size and less colored.
- Microcytic Hypochromic Anemia: RBCs are smaller in size and less colored.

Hemorrhagic Anemia occurs due to excessive loss of blood.
There are two types of hemorrhagic anemia:
- Acute Hemorrhage: sudden loss of a large quantity of blood, corrected within 4-6 weeks.
- Chronic Hemorrhage: loss of blood over a long period, often due to conditions like peptic ulcer, purpura, hemophilia, and menorrhagia.

Hemolytic Anemia occurs due to excessive destruction of RBCs.
There are two types of hemolytic anemia:
- Intrinsic Hemolytic Anemia: destruction of RBCs due to a defect within the cells themselves, often inherited.
- Extrinsic Hemolytic Anemia: RBCs are produced healthy but are later destroyed by external factors.

Nutrition Deficiency Anemia occurs due to a deficiency of a nutritive substance necessary for erythropoiesis.
The substances necessary for erythropoiesis are iron, protein, vitamin C, B12, and folic acid.
