Role of Hemoglobin in the body and Its Different Levels

role of hemoglobin in the body and its different levels

In this article we will look at the role of hemoglobin in the body and its different levels. Hemoglobin plays a significant role in our body. It is an iron rich protein in red blood cells. When the oxygen enters the lungs connects to the hemoglobin in the blood, which carries it to the other parts of the body. Our body’s billions of cells need oxygen to repair and maintain itself. Every hemoglobin protein can carry four molecules of oxygen. These molecules are delivered throughout the body by red blood cells. If someone has inadequate red blood cells, the body is left short of the oxygen it needs to function; now this condition is called as anemia.

How to check the level of Hemoglobin?

The levels of “hemoglobin or Hb” are mainly measured by a blood test. It is generally expressed in grams per deciliter or (g/dl) of blood. In children the normal level of hemoglobin varies according to age but if the blood test finds hemoglobin less than 13.5 g/dl in a man and 12 g/dl in a woman, then called as patient of anemia.

Different Levels of Hemoglobin

(a) High Hemoglobin Level

High hemoglobin caused by smoking, dehydration, living in high altitude or drinking alcohol. In case of high hemoglobin level the body makes too many red blood cells.  Blood becomes thicker than usual. This may lead to strokes, clots and heart attacks.

(b) Low Hemoglobin Level

Person with low hemoglobin level indicates that he/she is suffering from anemia. It occurs with the deficiency of iron and it is most common. Person who has gastric bypass surgery, pregnant woman, and person having blood forming stem cells in the bone marrow can have the low hemoglobin level. Even new born babies can have the temporary anemia their blood cells breaking down too quickly and which results in yellowing skin this condition is called as jaundice.

Some common symptoms of low hemoglobin level comprise chest pain, dizziness, weakness, shortness in breathe, headache, cold hand and feet, yellow skin and fast or irregular heartbeat.

How to maintain the normal Hemoglobin Level?

To maintain adequate or normal level of hemoglobin eat iron rich foods such as green leafy vegetables, dry fruits, nuts, meat, and dairy products. Do exercise so that hemoglobin circulation level can be maintain properly in the body.
