Hereof, what causes blood loss anemia?
Common causes of anemia include the following: Anemia from active bleeding: Loss of blood through heavy menstrual bleeding or wounds can cause anemia. Gastrointestinal ulcers or cancers such as cancer of the colon may slowly ooze blood and can also cause anemia.
In this regard, how is anemia treated with blood loss?
If you suddenly lose a large volume of blood, you may be treated with fluids, a blood transfusion, oxygen, and possibly iron to help your body build new red blood cells. If your blood loss is on-going, your doctor will find out what's causing the bleeding, stop it, and, if needed, treat you for iron-deficiency anemia.

- cold or clammy skin.
- pale skin.
- rapid, shallow breathing.
- rapid heart rate.
