Anaemias of oral significance

ABSTRACT

Anaemia is not a disease in itself. It is a sign of a single or multiple diseases. Anaemia is said to exist when the haemoglobin concentration is below normal for the age and sex of an individual. The synthesis and normal circulatory level of haemoglobin in any given individual depend on factors such as an adequate supply of haemopoietic nutrients, normal functioning of bone marrow, and proper utilization of haemoglobin. Based on these factors anemia can be broadly grouped into three categories 1. Anaemia due to lack of haemopoietic nutrients (nutritional anemia) 2. Anaemia due to bone marrow dysfunction (aplastic anaemia) 3. Anaemia due to excessive breakdown of red blood cells (haemolytic anaemia) (AU)
