What causes iron-deficiency anemia?

You can get iron-deficiency anemia from:

• Bleeding, either from losing a large amount of blood quickly (for instance, in a serious accident) or losing small amounts of blood over a long period of time. The body loses more iron with blood loss than it is able to replace with food. This can happen to women having heavy menstrual periods or in people who have inflammatory bowel disease.
• Not getting enough iron in the diet.
• Needing more iron than you did previously (for instance, during pregnancy or illness).

Some types of iron-deficiency anemia are called by other names related to the cause, such as anemia of chronic disease (also called anemia of inflammation) or acute blood loss anemia.
