Megaloblastic anemia is a type of macrocytic anemia. An anemia is a red blood cell defect that can lead to an undersupply of oxygen. [1] Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. [2] When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M ...
Signs of folate deficiency anemia most of the time are subtle. [4] Anemia (macrocytic, megaloblastic anemia) can be a sign of advanced folate deficiency in adults. [1] Folate deficiency anemia may result in feeling tired, weakness, changes to the color of the skin or hair, open sores on the mouth, shortness of breath, palpitations, lightheadedness, cold hands and feet, headaches, easy bleeding ...
Macrocytic anemias have several causes but with the implementation of folic acid fortification in North America, folate deficiency has become a rare cause of megaloblastic macrocytic anemia in that part of the world. [1] In this region, Vitamin B 12 deficiency is a far more common cause of megaloblastic macrocytic anemia. [1]
Other causes. The hematocrit is the ratio of the total volume of blood to the total volume of red blood cells, and is measured as part of a complete blood count. This is the primary test done to ...

Defined as those seen in any macrocytic, megaloblastic anemia: [1] Anemia: causing fatigue, conjuctival pallor, pale complexion, and in some cases, a mild icterus (yellowing of the eye). Glossitis ("shiny tongue"): shiny, glossy tongue. Cheilosis (stomatitis): Inflammation of the edges of the lips and the oral mucosa.
[1] [2] It is the main and most common cause of vitamin B 12 deficiency anemia in developed countries, [2] and is characterized by a triad of symptoms: Anemia with bone marrow promegaloblastosis (megaloblastic anemia). This is due to the inhibition of DNA synthesis (specifically purines and thymidine).
The presence of hypersegmented neutrophils is an important diagnostic feature of megaloblastic anaemias. Hypersegmentation can also be seen in many other conditions but with relatively less diagnostic significance. Hypersegmentation can sometimes be difficult to assert since interobserver variation is high and segmentation may vary with race.
