Hemoglobin is a general term that describes the molecule in erythrocytes that contains a heme group and iron. You also have what are called unstable hemoglobins which are usually genetic conditions were amino acid substitutions have taken place, one example is called Heinz bodies. Nevertheless, the primary function of hemoglobin is to transport oxygen to all body cells. All cells in the body must have a constant supply of oxygen to survive.

When hemoglobin levels are low cells, tissues, and organs are deprived of needed oxygen. Depending on exactly how low the hemoglobin level is determines the degree of anoxia. A slight drop in hemoglobin is compensated for by the body and has no major adverse effects. However, a very low hemoglobin level can be quite serious and can lead to organ damage and failure.

I noticed in your comments, "if it is not treated with iron and vitamins". Be advised that iron may or may not be needed. It depends on why the hemoglobin level is low. Iron supplements are not a cure all and furthermore they may be harmful, even toxic, if iron is not needed. Iron toxicity is a very serious situation.

I suggest you consult with your physician to determine the exact cause of the low hemoglobin. Treatment depends on the nature of the problem.

There could be many explanations regarding low hemoglobin levels. One of the main conditions that causes low hemoglobin levels is aplastic anemia. When a person has aplastic anemia, it means that their body does not produce enough new cells. Symptoms are fatigue and excessive bleeding. Other symptoms of low hemoglobin levels are irritability, and dizziness. Low hemoglobin levels can become dangerous so it is important to follow doctors orders.

Sometimes, slightly low hemoglobin levels are normal. Sometimes pregnant women have low hemoglobin levels and women who have just begun their menstrual cycles as well.

A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women. In children, the definition varies with age and sex. The threshold differs slightly between medical practices.
