What is nutritional deficiency anemia? What is megaloblastic anemia?
Understand the Problem
The question is asking for definitions and explanations regarding different types of anemia, specifically nutritional deficiency anemia and megaloblastic anemia. It seeks to clarify the causes and characteristics of these conditions.
Answer
Nutritional deficiency anemia results from nutrient lack; megaloblastic anemia involves large abnormal red cells due to B12/folate issues.
Nutritional deficiency anemia occurs due to lack of nutrients essential for red blood cell production, like iron, vitamin B12, or folic acid. Megaloblastic anemia, often caused by vitamin B12 or folate deficiency, results in large, abnormal red blood cells. Pernicious anemia is a subtype caused by impaired B12 absorption.
Answer for screen readers
Nutritional deficiency anemia occurs due to lack of nutrients essential for red blood cell production, like iron, vitamin B12, or folic acid. Megaloblastic anemia, often caused by vitamin B12 or folate deficiency, results in large, abnormal red blood cells. Pernicious anemia is a subtype caused by impaired B12 absorption.
More Information
Megaloblastic anemia includes forms caused by inadequate absorption of vitamin B12 (pernicious anemia) or folate (folic acid deficiency), leading to ineffective erythropoiesis.
Tips
Confusing pernicious anemia with general megaloblastic anemia. Pernicious anemia is specifically due to B12 absorption problems.
