What is Anaemia?
Anaemia, also spelled as Anaemia is the most common blood-related disorder which occurs mainly by the abnormally low levels of red blood cells. Anemia is caused due to deficiency of iron. Nutritional deficiencies—particularly iron deficiency—are the most frequent causes of anaemia; however, deficits in folate, vitamins A and B12 are also significant contributors. Anaemia can also be brought on by hemoglobinopathies and infectious conditions such as malaria, TB, HIV, and parasitic infections.
Anaemia is also referred to as the iron deficiency disorder because iron is required to produce haemoglobin, a protein in red blood cells that facilitates to carry oxygen all around the body. There are more than 400 types of anaemia, which are caused by blood loss, decreased in the production of red blood cells, the destruction of red blood cells, etc. Human bones from 4000 years ago have been introduced with symptoms of acute anaemia in Thailand.
