How can poor nutrition lead to anemia?

Video transcript

Hi, everyone. Here's our next question. Which of the following can result from poor vitamin B 12 or folate intake. A mega blastic anemia. B, sickle cell anemia, c hemolytic anemia or D iron deficiency anemia. Well, one thing we can rule out right away is iron deficiency anemia because that's a result of not intake, having poor intake of iron. And we're asking about what is caused by poor intake of vitamin B 12 or fate. So we can rule out choice D right away. You can also rule out pretty easily choice. B sickle cell anemia. Um That's a pretty commonly known condition to be known to be inherited. It's a genetic disorder caused by a mutation to the hemoglobin gene. So, not affected by or not caused by poor intake of vitamin D 12 or folate. So again, if you can't remember right away on a test, you can cut yourself down at least by two with two pretty obvious or well known choices. So now we're down to mega blastic or hemolytic. Well, when I see this hemolytic lytic makes me think of cell lying or breaking down. And hemolytic anemia is indeed caused by the destruction of red blood cells. So that would kind of give you a clue that it's probably not just the result of poor intake of a vitamin that can be caused by various factors. Anything that might cause uh destruction of red blood cells. Uh One of those being autoimmune disease, the immune system can attack red blood cells, but there are other things that can cause that as well. So, hemolytic anemia is more of an umbrella term for any condition that causes the destruction of red blood cells. So again, if we couldn't remember off the top of our head, the name of this, you might be able to eliminate your other answer. Choices with more well-known um or logical guesses and indeed choice. A is our correct answer. Mega blastic anemia is the result of poor vitamin B 12 or folate intake. Uh These two vitamins are necessary for normal DNA synthesis and red blood cell production. So without them, if you can't keep producing new red blood cells anemia will develop. So that is why mega blastic anemia is the our answer here. Choice. A resulting from poor vitamin B 12 or full a full eight intake. See you in the next video.
