Question

iron deficiency anemia is usually due to

dehydration

allergies

too much red meat in the diet

chronic blood loss

Explanation:

Iron - deficiency anemia occurs when the body lacks enough iron to produce an adequate amount of hemoglobin. Chronic blood loss is a common cause as it depletes iron stores. Dehydration affects fluid balance, allergies are immune - related reactions, and too much red meat (a good source of iron) is not a cause of iron - deficiency anemia.

Answer:

chronic blood loss
