Anaemia : Information
|Introduction : Anaemia|
The condition of having a lower-than-normal number of red blood cells or quantity of hemoglobin. Normal results vary, but in general are:
|Symptoms : Anaemia|
The most common symptom of anaemia is fatigue or weakness. Other signs and symptoms of anaemia include:
|Causes : Anaemia|
Three main cause of anaemia are:Blood loss Lack of red cell production High rates of red blood cell destruction
1) Blood loss: Blood loss is the most common cause of anaemia, especially in iron-deficiency anaemia. Blood loss can be short term or long term depending upon the conditions.
Bleeding in the digestive or urinary tract can cause blood loss. Surgery, trauma, or cancer also can cause blood loss. Heavy blood loss due to menstruation.
If a lot of blood is lost, the body may lose enough red blood cells to cause anaemia.
2) Lack of Red Blood cell production:
It can be due to "acquired" or "Inherited".
"Acquired" means that the person is not born with the condition, but may develop it at later stages.
"Inherited" means that the condition has been passed by the parents.]
Acquired conditions and factors that can lead to anaemia include:
Unusual hormonal levels Chronic diseases
Aplastic anaemia can also prevent body from making enough red blood cells. This condition can be both acquired or inherited.
3) High rates of RBCs destruction:
Factors that can cause destruction of red blood cells.
One condition can be an enlarged or diseased spleen.This is an acquired condition. Inherited conditions are the one when body destroy too many red blood cells. It can be in sickle cell anaemia, thalassemias, and lack of certain enzymes. These conditions create defects in the red blood cells that cause them to die faster than healthy red blood cells.Hemolytic anaemia is another example of a condition in which body destroys its red blood cells. Both inherited or acquired conditions or other factors can cause hemolytic anaemia. Examples include immune disorders, infections, certain medicines, or reactions to blood transfusions.
|Diagnosis : Anaemia|
Signs and symptoms like weakness, malaise or body aches
To check for the levels of hemoglobin (it is a protein that transports oxygen)
Red blood cells (cells that contain hemoglobin)is lower than normal.
Complete blood count (CBC): A CBC is generally done to know the number of blood cells in the blood. To check anaemia, physician will see the levels of the red blood cells contained in the blood (hematocrit) and the hemoglobin in blood. Normal adult hematocrit values vary from one medical practice to another but are generally between 38.8 and 50 percent for men and 34.9 and 44.5 percent for women.
A test to determine the size and shape of your red blood cellsSome of red blood cells may also be examined for unusual size, shape and color. This will help in diagnosis. For example, in iron deficiency anaemia, red blood cells are smaller and paler in color than normal. In vitamin deficiency anaemia's, red blood cells are enlarged and fewer in number.
|Management : Anaemia|
Iron supplements: The most commonly prescribed supplement is ferrous sulphate, taken orally (by mouth) two or three times a day. Dietary supplements: Iron-rich foods include:
|Medical Condition : Anaemia : Blood Lymphatic|
|Acquired Immuno Deficiency Syndrome|
|Adult Inclusion Conjunctivitis|
|Alcohol Abuse and Alcoholism|
|Alopecia (hair loss)|
|Avian influenza in humans|
