Anemia is a condition where the blood does not carry enough oxygen to the body's organs and tissues. It is most commonly caused by not having enough iron, which is needed to make hemoglobin. Hemoglobin is an iron-rich protein that carries oxygen from the lungs to the rest of the body and gives blood its red color. Anemia can be caused by blood loss, lack of red blood cell production, or high rates of red blood cell destruction. Common symptoms include tiredness, dizziness, shortness of breath, and headaches. Anemia is diagnosed through medical history, physical exam, and blood tests to check red blood cell and hemoglobin levels. Treatment depends on the underlying cause but often involves dietary changes to
