Anemia is a disease of the blood that is characterized by the decrease in the total number of red blood cells, the amount of hemoglobin in them or both at the same time. An anemia can have different origins and, according to these, it has different characteristics.
There are 3 types of anemia: Post hemorrhagic, Deficient and Hemolytic.
Post hemorrhagic ones are naturally those that are due to the loss of blood, they occur as a result of great traumatisms, sudden digestive hemorrhages, abortions, bleeding hemorrhoids, etc.
In the lack of necessary elements for the formation of red blood cells, usually lack of vitamin B12, lack of folic acid, etc. This could easily happen when losing weight fast
And finally the Hemolytic occurs when the destruction of red blood cells is carried out excessively fast.
Anemia can be detected in the evident blood loss, the diagnosis is based on the observation of symptoms. When a blood test is performed, a lower than normal number of red blood cells is detected.
