From the Mayo Clinic:
Hemoglobin is the iron-rich protein in red blood cells that gives blood its red color. The normal range of hemoglobin is approximately 14 to 17 grams per deciliter for men and 12 to 16 grams per deciliter for women. A low hemoglobin count indicates a low red blood cell count (anemia). Anemia can have many causes, including: * Vitamin and iron deficiencies * Acute or chronic bleeding * Hormone deficiencies, such as thyroid hormone or testosterone * Chronic diseases, such as kidney failure, cancer and Crohn's disease * Autoimmune diseases, such as lupus * Side effect of certain medications, such as chemotherapy drugs Treatment depends on the underlying cause.
Low hemoglobin level
This information can be used to help physician's diagnose and monitor anemia (a low hemoglobin level) and polycythemia vera (a high hemoglobin level).
if you have low levels of hemoglobin, you can expect to live for 12 hours longer.
Anemia is a deficiency in the amount of hemoglobin in the blood.
A hemoglobin level of 11.7 g/dL is considered low for adult males. Normal hemoglobin levels for adult men typically range between 13.8 to 17.2 g/dL. It is advisable to consult a healthcare provider for further evaluation and management if the hemoglobin level is low.
A hemoglobin level of 4.7 is dangerously low and if not properly treated could become fatal. Normally, women should have a hemoglobin level of 12 or more, men 13 or more. Generally, hospitals will begin emergency blood transfusions when the hemoglobin level drops below 7 or 8.
There is no correlation between hemoglobin and lung cancer. A high or low hemoglobin can mean any number of conditions; people with lung cancer can have any level of hemoglobin depending on situation and other conditions.
When Mean Corpuscular Hemoglobin level is low or commonly known as MCH, this means a person has iron-deficiency anemia. This type of anemia can be caused by insufficient iron in the diet or blood loss.
hemoglobin is reduced when the boby is lacking iron which is responsible for the formation of hemoglobin
It highly depend on the circumstance. Some bacteria will destroy the hemoglobin, and thus the hemolyzed blood appears transparents, whereas other process will only destroy the hemoglobin wall and thus liberating the hemoglobin, which is then pale cherry roughly in color.
A low MCHC (mean corpuscular hemoglobin concentration) level may indicate iron deficiency anemia or a genetic hemoglobin disorder. It means that there is a reduced amount of hemoglobin in each red blood cell, which can impact oxygen-carrying capacity and overall health. Further evaluation by a healthcare provider is recommended to determine the underlying cause.
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.
