Blood Cells of a Person with Anemia

What is anemia?

Anemia is a deficiency that negatively affects the production of hemoglobin (a substance present in red blood cells).

It is through hemoglobin that the blood carries oxygen to all parts of our body.

Understanding Anemia

Because all our cells rely on oxygen to perform their vital functions, anemia can lead to serious complications as it directly targets hemoglobin (oxygen and iron transporter protein).

The three main categories of anemia are excessive blood loss (which may lead to bleeding or chronic volume reduction), excessive destruction of blood cells (hemolysis) or deficiency in blood cell production.


Among the blood disorders, anemia is the most common. There are many types of anemia with unknown causes. Its classification will depend on the form it presents, and may be according to the symptoms presented, clinical aspects, etc.


The symptoms of this disease are not very clear, but the most common ones are: feeling weak or fatigued and, in some cases, difficulty concentrating. In the most severe cases can occur even from difficulty breathing during physical efforts, to heart problems. Anemia can lead a sick person to death if not treated properly.


There are many treatments for anemia, however, these will depend on the severity of each case.


Iron deficiency in our body is an important triggering factor of this disease.
