5.9.3. Blood diseases

Blood diseases

Some blood diseases are:

Anemia

The anemia occurs when the concentration of hemoglobin in the blood is low. It can also be accompanied by a decrease in the number of red blood cells. Since hemoglobin is responsible for the transport of oxygen, not enough oxygen reaches the tissues, which causes fatigue and tiredness.

Anemia can be caused by lack of iron fundamental component of hemoglobin, and other causes such as menstrual abundant, digestive disorders, etc.

5.23.- Why does a person with anemia get so tired?

Leukemia

The leukemia or "blood cancer" is a disease that affects cells of the bone marrow, the body to make the blood. There is an excessive increase in abnormal white blood cells, decreasing the number of red blood cells and platelets. But these white blood cells are unable to fight infection.

This is why people with leukemia have frequent infections, anemia, and blood clotting problems.

The bone marrow transplant is an effective treatment against this disease.

Curiosity: José Carreras.

Hemophilia

The hemophilia is an inherited disease that causes problems in the coagulation of blood. Substances called clotting factors are necessary for clotting to occur, and hemophiliacs lack some of these factors. Therefore, any injury can lead to significant blood loss.

Curiosidad: La hemofilia, la enfermedad real.

Thrombosis

The thrombosis occurs when a formed blood clot inside an artery. This clot can remain attached to the wall of the artery or travel to another smaller artery and block it (embolism), preventing blood from reaching an organ, and can cause death if it is a vital organ.
