Erythrocytosis - Causes and Symptoms

What Is Anemia Disease?: Causes, Symptoms & Treatment

Anemia is a condition in which the number of red blood cells in the blood falls below normal. The symptoms of anemia are mainly attributable to the reduced availability of oxygen in the tissues, since red blood cells are essential for the transport of this gas in the bloodstream.

The reduction in the erythrocyte population (red blood cells are known as erythrocytes), as well as in hemoglobin values ​​(the pigment contained in them with the task of transporting oxygen), can be caused by reduced synthesis or increased destruction (anemia hemolytic) of the erythrocytes, from their functional or structural anomalies (sickle cell anemia), from the increase in blood volume (pregnancy, start of long-term physical activity) or from losses linked to hemorrhagic phenomena (acute bleeding of traumatic origin or linked to chronic diseases).

Among the most common causes of anemia are iron deficiency (iron deficiency anemia) or other nutrients (megaloblastic and pernicious anemia due to folate and vitamin B12 deficiency), some chronic diseases (peptic ulcer, ulcerative colitis, cancer, rheumatoid arthritis), autoimmune diseases (hemolytic anemia), bone marrow dysfunction (lymphoma, leukemia, multiple myeloma), pregnancy, intoxications including iatrogenic origin (certain drugs), parasitic infections (malaria), renal failure and hereditary diseases such as thalassemia.

The most suitable therapy for resolving anemia must aim to resolve the causes that generated it.
