Megaloblastic Anemias (MGA) are rare blood disorders characterized by the presence of large, structurally and visually abnormal, immature red blood cells (megaloblasts). Decreased numbers and immaturity of white blood cells (leukocytes) and blood platelets (thrombocytes) may also occur. Megaloblastic Anemias are usually caused by a deficiency or defective absorption of either vitamin B12 (cobalamin) or folic acid. As a result, they are also known as the vitamin deficiency anemias. In most cases, the fundamental flaws leading to the several forms of MGA caused by vitamin deficiencies are present at the time of birth and exist as a result of a genetic defect. In addition, certain antitumor or immunosuppressive drugs may also cause Megaloblastic Anemia.

In addition to the cells being large, the inner contents of each cell are not completely developed. This malformation causes the bone marrow to produce fewer cells, and sometimes the cells die earlier than the 120-day life expectancy.

Megaloblastic anemia, also called pernicious anemia, is a type of anemia characterized by very large red blood cells. In addition to the cells being large, the inner contents of each cell are not completely developed. This malformation causes the bone marrow to produce fewer cells, and sometimes the cells die earlier than the 120-day life expectancy. Instead of being round or disc-shaped, the red blood cells can be oval. What causes megaloblastic (pernicious) anemia? There are many causes of megaloblastic anemia, but the most common source in children occurs from a vitamin deficiency of folic acid. Other sources of megaloblastic anemia include the following: digestive diseases Certain diseases of the lower digestive tract can lead to megaloblastic anemia. These include celiac disease, chronic infectious enteritis, and enteroenteric fistulas. malabsorption Inherited congenital folate malabsorption, a genetic problem in which infants cannot absorb folic acid in their intestines, can lead to megaloblastic anemia. This requires early intensive treatment to prevent long term problems such as mental retardation.
