One of the forms nutritional anaemia which is characterized by the formation of larger than normal cells of the erythropoietic process. The cells are characterized based on the cell size which is larger than normal cell size( RBC size).
megaloblastic anaemia can be divided into folate deficiency and Vit.B12 deficiency anaemia. Deficiencies of either of these vitamins produce a general index with such features like anorexia, weight loss, poor memory, weakness and malaise. In this kind of anaemia, cells that are actively growing and dividing are particularly liable to be affected.
