Overview What is iron-deficiency anemia? Iron-deficiency anemia is a blood disorder that affects your red blood cells. It’s the most common form of anemia. It happens when your body doesn’t have enough iron to make hemoglobin, a substance in your red blood cell that allows them to carry oxygen throughout your body. As a result, iron deficiency may cause you to feel short of breath or tired. These symptoms develop over time. When iron deficiency is diagnosed, you may be prescribed iron supplements. Healthcare providers will also ask questions and do tests to determine why you developed iron deficiency. How does iron-deficiency anemia affect my body? Iron-deficiency anemia symptoms happen over time. Initially, you may have low iron and feel fine or have symptoms that are so mild you don’t notice them. Left untreated, however, iron-deficiency anemia can make you feel tired and weak. You may notice pale skin and cold hands and feet. Iron-deficiency anemia can also cause you to feel dizzy or lightheaded. Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath. Iron deficiency can cause you to have unusual cravings for non-food items such as ice, dirt or paper. How does iron-deficiency anemia develop? Normally, your body brings in a steady flow of iron from the food you eat. Your body stores excess iron so it’s available as needed to make hemoglobin. Iron-deficiency anemia develops when your body uses the iron stores faster than they can be refilled, or when the flow of iron into your system has slowed. This occurs in three stages: First stage: Iron stores are depleted. In this stage, the supply of iron to make new hemoglobin and red blood cells is dwindling but hasn’t yet affected your red blood cells. Iron stores are depleted. In this stage, the supply of iron to make new hemoglobin and red blood cells is dwindling but hasn’t yet affected your red blood cells. Second stage: When iron stores are low, the normal process of making red blood cells is altered. You develop what’s called iron-deficient erythropoiesis, sometimes called latent iron deficiency. Erythropoiesis is the medical term for the process of producing new red blood cells. In this stage, your bone marrow makes red blood cells without enough hemoglobin. When iron stores are low, the normal process of making red blood cells is altered. You develop what’s called iron-deficient erythropoiesis, sometimes called latent iron deficiency. Erythropoiesis is the medical term for the process of producing new red blood cells. In this stage, your bone marrow makes red blood cells without enough hemoglobin. Third stage: Iron-deficiency anemia develops because there isn’t enough iron to make hemoglobin for red blood cells. In this stage, the hemoglobin concentration will drop below the normal range. This is when you may begin noticing iron-deficiency anemia symptoms. Who’s likely to develop iron-deficiency anemia? Almost anyone can develop iron-deficiency anemia. That said, women who have menstrual cycles or who are pregnant or breastfeeding are more likely to develop iron-deficiency anemia than women who have gone through menopause or men. Here are other groups of people who have an increased risk of developing iron-deficiency anemia: Some infants between ages 6 months and 12 months: Babies are born with iron they received from the person who carried them through gestation. That iron supply runs out after four to six months. Babies who are breastfed only or drink unfortified formula may not get enough iron.
