Anemia

Can you develop Anemia over time, or do you contract it at birth?

[Setaka]

There are various types of anemia and you'd need a blood work up to determine "what", "which", and "why".

For example:  There's megaloblastic anemia, pernicious anemia to name just a couple.

Please see a doctor for a blood work up if you believe you are anemic.  Some treatment can be as little as recurrent B12 injections because you don't absorb it as well.
