Question 13

List one cause of regenerative anemia and one cause of non-regenerative anemia.

Answer 13

Regenerative anemia causes:
- any cause of blood loss outside the body (hemorrhage, gi parasites, fleas, immune-mediated hemolysis)

Non-regenerative anemia causes (etiologies)
- any cause that won’t let the body make new blood (bone marrow disease, chronic kidney failure, hypothyroidism, iron deficiency)
