What are megaloblastic changes?
Megaloblastic anemia is a condition in which the bone marrow produces unusually large, structurally abnormal, immature red blood cells (megaloblasts). Bone marrow, the soft spongy material found inside certain bones, produces the main blood cells of the body -red cells, white cells, and platelets.
What are megaloblastic features?
Megaloblastic 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.
What is the most common cause of megaloblastic anemia?
Some people can’t absorb enough vitamin B12 from their diet, leading to megaloblastic anemia. Megaloblastic anemia caused by vitamin B12 deficiency is known as vitamin B12 deficiency anemia.
What is megaloblastic hematopoiesis?
Megaloblastic hematopoiesis is a hypercellular bone marrow failure syndrome intimately linked with abnormal cobalamin (B12) and folate metabolism or deficiency. These nutrients have a critical role in the synthesis of DNA.
What diseases cause high folate levels?

- Pregnancy.
- Celiac disease.
- Crohn’s disease.
- Inflammatory bowel syndrome (IBS)

What do enlarged blood cells indicate?
Macrocytosis is a condition in which your red blood cells are larger than they should be. While it isn’t a condition of its own, macrocytosis is a sign that you have an underlying health condition and may lead to a severe form of anemia called macrocytic normochromic anemia.
Which infection causes megaloblastic anemia?
The common causative agent (D. latum) is a large tapeworm that can reach a length of 20 meters. One of its more conspicuous clinical manifestations in humans is megaloblastic anemia, which is caused by the parasite intake of vitamin B12 or folic acid within the host.
What happens if your folate is too high?
It can cause symptoms like weakness, fatigue, difficulty concentrating, and shortness of breath ( 14 , 15 ). If you take folic acid supplements and recognize any of these symptoms, consider getting your B12 levels checked. High intakes of folic acid may mask a vitamin B12 deficiency.
