Anemia is long considered a disease associated with malnutrition or severe absence of nutritional value that is crucial to maintain a balanced as well as healthy proportion of red blood cells in the blood. But with the recent growth of the disease as a life threat even to the affluent peoples of developed countries or sections of the society, the medical facts on anemia established that other than poverty or poverty related malnutrition there are many other factors which have a huge bearing in causing the disease. Let us look at various aspects of the disease starting from medical definition of the disease, causes, symptoms and finally global statistics on the disease.
In describing the very basic and simple medical facts on anemia the definition of the disease can be stated as the unusual decrease of red blood cells or hemoglobin in the blood. Red blood cells or hemoglobin is the main part of blood cells that is crucial to carry and bind oxygen with it to deliver oxygen to various parts of the body and we all know for us to survive and function with our organic functions a steady supply of oxygen through the blood stream is truly important. So, in nutshell with the shortage or crisis of red blood cells or hemoglobin in the blood flow when the body suffers from a steady flow of oxygen in the blood stream it is called anemia.
Anemia is a disease associated with the red blood cells of our blood stream that can be of various types. Anemia can be as severe as to threatening for life or mild to get cured with proper medication within weeks. There are more than 400 different types of anemia each with its own set of distinct areas of contributing factors and causes.
Deficiency of iron in the blood or deficiency of other nutrients like certain vitamins and acid or medical causes like intake of certain medicines or severe medical conditions like stomach ulcer, there can be innumerable contributing factors or causes of anemia according to the particular type of anemia. Anemia is classified into various types according to these causes more than the syndromes.
In providing here the medical facts on anemia explaining some major types of anemia is extremely important for the understanding of the disease. Here we would provide brief details on some of the major types of anemia. Anemia is classified mainly in accordance to various medical conditions that correspond to either loss of red blood cells without any difficulty in production of red blood cells or various types of malfunctions relating to the production of required hemoglobin in the blood.
Anemia due to excessive blood loss
Bleeding causes a person to lose red blood cells. In case of acute bleeding the blood loss gets appropriate and proper treatment and normally even if the anemic conditions developed due to blood loss, it gets cured as soon as the normalcy is restored. But in case of chronic bleeding the person loses blood for a long time without the fact being medically detected for a long time and continuous loss of red blood cells can ultimately cause anemia. Several ulcers, some types of cancers, benign gastric ulcers and gastric problems, hemorrhoids, childbirth and menstruation in women can cause continued blood secretion in women and in turn can cause anemia. Surgeries and use of non steroidal anti inflammatory drugs can also cause severe blood loss and in some cases can cause anemia.
Red blood cells destruction or Hemolysis anemia
This is the most major classification of anemia and unlike the previous one it is also the most challenging also. Every red blood cell in our body has a life cycle which is normally 110 to 120 days but if the red blood cells die prematurely then the body may suffer from the shortage of hemoglobin and this anemia is mainly caused by external causes like infection, some medications and some medicinal procedures like heart lung bypass machine use, Hemodialysis for kidney problems etc. Toxin reaction from poison can also cause this anemia and can be severe. Immune reaction in a great many cases of this anemia is seen as a major cause.
Anemia caused by deficient red blood cells
According to this medical observation this type of anemia is caused either by less production of red blood cells or the red blood cells in the blood stream not working properly. Iron deficiency, vitamin deficiency and deformed shape of red blood cells that make the cell break faster than usual are the main causes of this anemia.
From the above mentioned medical facts on anemia and the medical conditions that is responsible for this disease it is evident that anemia other than so called nutritional deficiencies has got many other contributory factors related to the development of other diseases and physical disorders of diverse types.
Apart from the so called medical facts on anemia global statistics to assess the reach of the disease is also important. Globally anemia is one of the diseases that is on the rise with the passing of everyday and in developed first world or impoverished third world or in aspiring developing nations the disease is rising to be one of the gravest public health threats. While in the first world or developed economy or in developed civic societies the disease is mainly the outcome of other health complications in poor countries this is associated with malnutrition and imbalance in the production of red blood cells. In the United States alone 3.5 million people are suffering from anemia. Surprisingly in the global top 15 chart of number of deaths caused by anemia except 3 or four nations all are from economically developed west or far eastern countries and thus the long standing myth of malnutrition being the main cause of anemia can be taken as groundless. The first five countries with highest number of deaths from anemia are Egypt, United States, Spain, Mexico and Germany.
