Anemia - Symptoms, Causes, Prevention, and Treatment

What Is Anemia?

Anemia is a condition where the red blood cells (RBC) are too low in the body. As these cells carry oxygen to different organs of the body, anemia results in the amount of oxygen in your blood to get lower than normal. Most of the symptoms caused are due to decreased oxygen supply to the vital organs of the body.

Anemia is diagnosed by measuring the amount of hemoglobin, which is a protein found in RBC and is responsible for carrying oxygen from the lungs to the rest of the body. It is being estimated that more than 1.6 billion people are affected by anemia worldwide. Women and people with chronic diseases like cancer are at risk of developing this condition.

What Causes Anemia?

About 0.8 to 1 % of the body's RBC are replaced each day, and the normal lifespan for red cells is 100 to 120 days. Any procedure that negatively affects this balance between red blood cell production and destruction can cause anemia. The factors that typically decline red blood cell production are:

1. The hormone erythropoietin does not adequately stimulate the production of red blood cells.

2. Consuming a diet lacking in iron, vitamin B12, or folate.

3. Hypothyroidism.

4. Endometriosis.

5. Accidents.

6. Gastrointestinal injuries.

7. Menstruation.

8. Childbirth.

9. Excessive uterine bleeding.

10. Surgery.

11. Liver cirrhosis.

12. Fibrosis of the bone marrow.

13. Liver and spleen disorders.

14. Thalassemia.

Anemia due to iron, vitamin B12, and folate deficiency is treated with nutritional supplements. At times, B12 injections are required.

At times, if the anemia is severe, doctors use erythropoietin injections to increase red blood cell production in the bone marrow. If bleeding happens or the hemoglobin level is low, a blood transfusion may be important.
