    Anemia is a condition in which you don't have enough red blood cells to carry oxygen throughout your body. It can be mild or severe and can be caused by a wide range of factors, including iron or vitamin deficiency, pregnancy, blood loss, exposure to toxic chemicals, and certain disorders and diseases, such as ulcers, Crohn's disease, HIV/AIDS, and cancer. Left untreated, anemia can lead to shortness of breath, chest pain, dizziness, and nerve or organ damage. Most types of anemia can be treated with dietary changes, supplements, vitamin injections, or medications. When severe, surgery, blood transfusions, or bone marrow transplants may be needed.
