Hemoglobin is a protein in your red blood cells that transports oxygen from your lungs to the rest of your body and removes carbon dioxide from the lungs. The body is able to make hemoglobin through iron, a natural mineral found in red blood cells. Having low hemoglobin can hurt the body and could lead to serious health issues, including heart problems. When the cause of low hemoglobin is low iron levels, the condition is called iron deficiency anemia. This article will review the causes, symptoms, and treatment of low hemoglobin and will describe what you can do to help prevent your hemoglobin levels from getting too low. There Are Different Types of Anemia There are different types of anemia. Iron deficiency anemia is just one type of anemia. Pernicious anemia, aplastic anemia, and hemolytic anemia are some of the other types.
