It is very important for the body to be able to circulate enough oxygen from the lungs to all the different organs of the body.
To do this, it needs a special kind of protein found in the red blood cells that has the function to absorb oxygen from the lungs and carry it to other parts of the body, as well as absorb carbon dioxide to transport back to the lungs.
The protein is known as hemoglobin, making it very important for a person to have normal hemoglobin levels.
Normal Hemoglobin Levels
Below are some facts about hemoglobin levels.
1. Male and female
The normal hemoglobin level for men differs from that of women.
A normal level for men is between 13.5 grams to 17.5 grams per decilitre of blood. A woman should have between 12.0 grams and 15.5 grams per decilitre of blood.
You may also want to take note that, in most medical circles, it will be more common to refer to hemoglobin level as HB or HB count.
2. Hemoglobin levels in children
The normal level for children varies a lot according to their age and sex.
Sometimes, the medical practice in a particular country may have different normal levels for children of certain age and sex.
3. Oxygen levels
People with low oxygen levels in the body like individuals who usually climb mountains where the air is thin will have higher hemoglobin levels because their body tries to increase production of red blood cells to compensate for the limited supply of oxygen.
4. Low hemoglobin count
Having a low hemoglobin count is not necessarily a sign of anemia.
Some people may have lower than normal levels of hemoglobin, but may still have a lot of blood in their body. This is usually caused by a lack of sufficient iron in their diets.
5. Effects of tea and coffee
Drinking too much tea and coffee can result in low levels of hemoglobin.
Tea and coffee have certain properties within them which reduce the absorption of iron which is necessary for the production of hemoglobin in the body.
6. Energy levels
Having low levels of hemoglobin in the body can reduce energy levels. The oxygen being carried by hemoglobin is necessary in the transformation of food into energy.
7. Associated medical conditions
Having a constant higher than normal level of hemoglobin or red blood cells, can be considered as a symptom of polycythemia vera, which is a disorder in the bone marrow responsible for the production of red blood cells.
It produces the cells more than required.
Having a higher concentration of red blood cells and hemoglobin in the body can help someone endure a long distance run with greater ease as a result of increased supply of oxygen to the muscles and other parts of the body.
9. High hemoglobin levels
High levels of hemoglobin can be an indicator of a cancerous infection. Most cancers trigger the body’s production for more red blood cells.
10. Sickle cell disease
Sickle cell is a disease closely associated with a lower than normal hemoglobin level.
A patient’s red blood cells tend to form the shape of a sickle which prevents them from carrying enough hemoglobin and oxygen to the muscles and other parts of the body.
Many people with sickle cell have an HB lower than 10grams per decilitre.
