6 Causes for anemia

Anemia is one of the most prevalent diseases worldwide, especially in developing countries. Anemia develops due to many reasons such as:

  1. Qualitative or quantitative malnutrition, which is associated with diminished intake of minerals and vitamins, especially iron and vitamins B6 & B12.
  2. Increased demand of iron or vitamins B6 & B12; especially among children, adolescents, pregnancy and lactating women.
  3. Internal or external hemorrhage as in piles or invasive wounds… etc.
  4. Excessive menstrual blood (as in menorrhagia or polymenorrhea).
  5. Digestive disorders or malabsorption that interferes with digestion or absorption of nutrients.
  6. Blood disorders such as sickle cell anemia or hemolytic anemia…etc.

The clinical picture of anemia consists of the following:

  • Frontal headache that may extend to the forehead and orbital region.
  • Dyspnea and shortness of breathing.
  • Continuous fatigue and desire to sleep.
  • Marked pallor.
  • Loss of appetite.
  • Hair loss and brittle nails.
  • Hypotension and tachycardia.

Anemia is diagnosed by complete blood count (CBC), which shows decreased hemoglobin level. Management of anemia usually includes oral or IV iron supplementation. In severe cases, anemia is managed by blood transfusion.
