severe anemia

Severe anemia is one of the most common diseases, in which there is a decrease in the concentration of hemoglobin in the blood from its normal level, which should be 11 grams per deciliter for adult females, and 13 grams per deciliter for males, thus reducing the percentage of oxygen that the body needs to carry out its normal functions.[1]

Severe anemia occurs in three types: anemia resulting from the loss of a large amount of blood, anemia resulting from a defect in the number of red blood cells produced by the body, and hemolytic anemia that occurs as a result of the breakdown of red blood cells before the completion of their normal lifespan, which It has a duration of 120 days.[1]

Symptoms of severe anemia

The main symptoms of severe anemia are:[2]

  • Feeling tired and stressed.
  • Difficulty breathing, and chest pain.
  • Paleness and cyanosis, or yellowing of the face, as a result of the breaking of red blood cells, and the conversion of hemoglobin into bilirubin.
  • Coldness of the extremities of the body, especially the feet.
  • Severe headache.
  • Loss of ability to focus, frequent forgetfulness.
  • Feeling dizzy and nauseous.
  • Arrhythmia.

Causes of severe anemia

Among the causes of anemia:[3]

  • Hereditary hemolytic anemia, which is a defect in the gene responsible for the production of red blood cells.
  • An increase in the number of spherical red blood cells, which is a genetic disease that occurs in the production of spherical red blood cells, but they are abnormal, which leads to an imbalance in the function of red blood cells, so the spleen breaks them and removes them from the blood circulation.
  • Polycythemia vera ovale, which is also a genetic disease, in which the production of red blood cells in an oval and abnormal shape occurs.
  • Thalassemia, which is a defect in the production of hemoglobin in red blood cells, which leads to a weakening of their ability to transport oxygen through the blood.
  • Infection with folate hemolysis, which is a weak ability to manufacture the enzyme glucose hexa-phosphate dehydrogenase, which leads to a break in red blood cells, and severe anemia.
  • Sickle cell anemia, a disease in which red blood cells become infected, in which a defect occurs in the production of hemoglobin in red blood cells, so they become abnormal, and their shape becomes sickle.
  • Stay away from eating foods and foods that contain a high percentage of iron, which is one of the most important elements responsible and stimulating to increase the proportion of blood in the body.
  • Deficiency of pyruvate kinase, an enzyme needed to build red blood cells, and its deficiency leads to their breakdown and deficiency in the blood.
  • Experiencing severe bleeding, such as deep cuts, or miscarriage.
