Anaemia is a disease in which the haemoglobin or the red blood cell calculation is below the normal level. Usually the normal level of haemoglobin differs in case of males and females. In case of men, anaemia is by and large classified as haemoglobin level below 13.5 gram/100 ml and in case of women as haemoglobin below 12.0 gram/100 ml. These classifications may differ to some extent relying on the basis and the laboratory reference taken into consideration.
Signs and Symptoms of Anaemia:-
Oxygen delivery to every tissue in the body reduces due to a low red blood cell count, anaemia may begin a variety of indications and warning signs. Due to anaemia the situation of other primary diseases may become bad. Where anaemia is meek, no symptoms may be observed. If anaemia is chronic, the body may modify and make up for the change; in such case also unless the anaemia is very acute there may be no indications.
The indications of anaemia may consist of the following:
- decreased energy
- shortness of breath
- looking pale
- palpitations (feeling of the heart racing or beating irregularly)
Causes of anaemia:-
Any development that can disturb the usual lifetime of a red blood cell may be the reason for anaemia. By and large the lifetime of a red blood cell is approximately 120 days. Red blood cells are formed in the bone marrow.
The reason for anaemia may be either:
- an increase in loss or demolition of red blood cells, or
- a decline in production of red blood cells or haemoglobin.
A very common categorization of anaemia is found on the Mean Corpuscular Volume (MCV) which indicates the regular volume of a person’s red blood cells.
1. In case the MCV is less than 80, the anaemia is classified as microcytic anaemia.
2. On the other hand, where MCV is in the standard range (80-100), it is named anormocytic anaemia.
3. However where the MCV is high, then it is called a macrocytic anaemia.
