Iron deficiency is a type of anemia. It is a condition in which the blood does not have enough healthy red blood cells, and therefore causes a shortage of iron in the body. Bone marrow needs iron to make hemoglobin. Without enough iron, the body can't produce enough hemoglobin for red blood cells. This type of anemia is often caused by blood loss, such as from heavy menstrual bleeding, an ulcer, cancer, a polyp somewhere in your digestive system, and prolonged use of aspirin or drugs known as nonsteroidal anti-inflammatory drugs.

The symptoms of iron deficiency anemia may include:

·       Inflammation or soreness of your tongue

·       Chest pain or a fast heartbeat

·       Weakness or extreme fatigue

·       Shortness of breath, dizziness or lightheadedness

·       Pale skin or brittle nails

·       Frequent infections

·       Headache

·       Cold hands and feet

·       Unusual cravings or a poor appetite

·       An uncomfortable tingling or crawling feeling in your legs (restless legs syndrome)
