High hemoglobin - causes

High hemoglobin means that the blood content of red blood cells is increased. Even in a completely healthy person, the level of hemoglobin can fluctuate in a fairly large range. Normal indicators of hemoglobin are:

• for women in the range of 120-140 g / l (grams per liter of blood);
• for men - 135-160 g / l.

If the excess of the norm is more than 20 units, we can talk about increased hemoglobin.

When does the hemoglobin level rise?

The reasons for the very high hemoglobin content in the blood can be divided into:

• physiological;
• pathological.

A significant increase in hemoglobin is dangerous for the body in that increased viscosity of blood can cause stroke or myocardial infarction. Blood can condense because of strong dehydration of the body during vomiting and diarrhea. This causes a decrease in the amount of circulating blood.

The body begins to produce an increased number of red blood cells in such cases:

1. When the body lacks oxygen because of its poor, insufficient transportation to tissues.
2. When the volume of blood plasma is significantly reduced, which leads to the development of a large number of red blood cells.

As a rule, the level of hemoglobin in the blood is increased:

1. People living high in the mountains or on the plains, but high above sea level. The air is rarefied, the oxygen content in it is lowered, here are the cells of the body and lack oxygen and compensate for it by intensive production of hemoglobin.
2. At physical overloads - at sportsmen who are engaged in winter kinds of sports, athletes, and also at mountaineers.
3. People who often fly on airplanes - pilots, stewardesses.
4. Men and women who smoke actively. The body lacks pure oxygen due to clogging of the lungs and begins to actively develop red blood cells.

Causes of high hemoglobin levels in the blood

There are quite a few reasons for elevated hemoglobin. This is due not only to changes that occur in the body with age, but also with a number of other factors.

The main causes of high hemoglobin in the blood can be called:

• increased glucose in diabetes mellitus;
• a large amount of hemoglobin in the blood plasma (hemoglobinemia);
• excessive formation of erythrocytes in the blood (erythrocytosis);
• thickening of the blood;
• oncological diseases;
• poor intestinal permeability;
• cardiovascular failure;
• lung diseases - pneumonia , bronchitis of different severity, asthma, tuberculosis, emphysema and others.
• an overabundance in an organism of vitamins of group "В" - В9, В12.

Causes of high hemoglobin in pregnant women

At approach of pregnancy the organism of the woman is reconstructed, starts to test new for it influences. The level of hemoglobin falls somewhat due to the fact that the fetus takes some iron, and future mothers begin to increase it with iron-containing multivitamins. As a result, hemoglobin in the blood rises to 150-160 g / l. But then the blood gradually thickens, the fetus begins to lack oxygen and nutrients due to lower circulation of blood flow. It is extremely undesirable for blood clots to appear, and therefore it is necessary to consult a doctor immediately if the hemoglobin level exceeds 150 g / l of blood.

The cause of increased hemoglobin during pregnancy may be exacerbation of chronic diseases, especially the heart and lungs.

The area where the pregnant woman lives can also cause increased hemoglobin. As stated earlier, finding high above sea level contributes to the production of excess protein. Do not overload yourself and excessive physical exertion.
