Anemia can occur due to hemolysis, malignancy, infections, or renal failure leading to blood loss.

Situations like pregnancy or infancy can heighten the need for iron.

Deficiencies in vital nutrients like B12 and folic acid can impede RBC production.

Problems in bone marrow can interfere with the production of red blood cells.

RBCs develop through four stages: proerythroblasts, erythroblasts, reticulocytes, mature RBCs.

Symptoms include fatigue, dizziness, headache, dyspnea, and pale skin.

A hormone that stimulates the production of red blood cells in response to low levels of RBCs.

Treatments include iron supplements, Vitamin B12, folic acid, and erythropoietin.
