Anemia symptoms, causes and prevention

Anemia is a condition in which the number of red blood cells or amount of hemoglobin (oxygen carrying protein) in red blood cells is below normal. Red blood cells contain hemoglobin, which allows them to transport oxygen from the lungs and deliver to all parts of the body.

Anemia causes the reduced number of red blood cells or amount of hemoglobin in red blood cells, so blood can not transport oxygen in the body as needed.

CAUSE
A common cause of anemia:

1. heavy bleeding
* Acute (sudden)
- Accidents
- Surgery
- Childbirth
- Broken blood vessels
* Chronic (chronic)
- Bleeding nose
- Hemorrhoids (haemorrhoids)
- Peptic ulcer
- Cancer or polyps in the gastrointestinal tract
- Kidney or bladder tumors
- Menstrual bleeding very much.

2. Reduced red blood cell formation
- Iron deficiency
- Lack of vitamin B12
- Lack of folic acid
- Lack of vitamin C
- Chronic Disease.

3. Increased destruction of red blood cells
- Enlargement of the spleen
- Damage mechanics on red blood cells
- Autoimmune reactions against red blood cells
- Paroxysmal Nocturnal Hemoglobinuria
- Hereditary Spherocytosis
- Hereditary Elliptositosis
- Lack of G6PD
- Sickle cell disease
- Hemoglobin C disease
- Diseases of hemoglobin S-C
- Hemoglobin E disease
- Thalassemia.


SYMPTOMS
The symptoms are caused by insufficient oxygen supply to these needs, varies. Anemia can cause fatigue, weakness, lack of energy and the head was floating. If the anemia gets worse, can lead to stroke or heart attack.


Diagnosis
Simple blood tests can determine the presence of anemia. The percentage of red blood cells in total blood volume (hematocrit) and the amount of hemoglobin in a blood sample can be determined. The examination is part of the complete blood counts (CBC).
