Causes of hematocrit and what does this mean?

Hematocrit is one of the indicators of blood, measured as a result of a general analysis, it expresses the proportion of corpuscles in the whole volume of blood. Uniform corpuscles are represented by erythrocytes, platelets and leukocytes, but since most of them( about 99%) are red blood cells, hematocrit is associated with the content of these cells and the ability of the blood to carry oxygen.

36% -48% taken for the hematocrit rate( HCT), but there is a dependence of the hematocrit rate on age, gender and individual characteristics. Increased hematocrit as a result of this may be due not only to existing diseases, but also to the normal physiological state of a person.

Reasons why hematocrit is elevated?

Physiological causes of

As a result of some changes in the body, the composition of the blood “adjusts” to them, as a result of which an increase in hematocrit in the blood can occur. These factors include:

  1. Age

Newborns have a large amount of red blood cells in the blood, so at first glance it can be concluded that there is an increased hematocrit in the baby’s blood. However, the indicator of 44-62% actually keeps within norm. Three months later, the hematocrit goes down to 32-44%, and after another 9 to 31-40%.

  1. Dehydration

The body seeks to compensate for the lack of water by decreasing plasma in the blood, so the total circulating blood volume( BCC) decreases, and the proportion of red blood cells in it increases, resulting in an increased hematocrit in the blood. Dehydration can occur with low water consumption, excessive sweating, frequent diarrhea and vomiting. Hematocrit increased during pregnancy at the stage of toxicosis.

  1. Hypoxia

Smokers are often deficient in oxygen - hypoxia. For the transportation of oxygen to all organs and the removal of carbon dioxide from them, hemoglobin is a component of the red blood cells. If less oxygen is supplied than needed, the body tries to compensate for this by additional hemoglobin production. As a consequence, the number of red blood cells increases and the hematocrit of HCT is increased in the blood test.

Hypoxia can also occur in people who have spent several days in the mountains. Their lungs had not yet managed to adapt to the exhausted mountain air containing less oxygen, therefore the hematocrit increases.

Factors causing increased hematocrit may be caused by diseases and deviations in the functionality of any organs or systems.

Since elevated hematocrit is a condition in which the proportion of blood cells( mainly red blood cells) increases, excessive production of these cells or the synthesis of erythropoietin, which stimulates the maturation of red blood cells, can cause it. In this case, a blood test will certainly show that hematocrit and hemoglobin are elevated. This condition may indicate the following diseases:

  • Kidney ischemia
  • Iron deficiency anemia
  • Bone marrow diseases
  • Hormonal drugs
  • Emotional stress

Elevated hematocritis in women may result from the appearance of women in the same period of time, or in the same period of time, if you are in a hysterogenic group, you can have anxiety,

  • , and hemorrhoids.

    If hematocrit is elevated in an adult or child due to a decrease in blood volume, attention should be paid to the following causes:

    • Excessive superficial or deep burns( more than 10%)
    • Inflammation of the peritoneum
    • Heart failure, which results in the accumulation of abdominal fluid
    • Diabetes mellitus
    • Pulmonary insufficiency

    Consequences of

    Increasing the proportion of corpuscles in blood volume always increases blood viscosity, this increases the risk of blood clottingDov and the formation of blood clots. The appearance of blood clots creates the risk of myocardial infarction, ischemic stroke, gangrene and even death.

    That is why it is important not to ignore the elevated hematocrit, but to take a series of actions to normalize this indicator in a timely manner.

    The danger of hematocrit elevation is especially observed when HCT increases to 55%.

    Successful treatment and stabilization of the level of HCT is to eliminate the root cause. In some cases, no special methods can be applied, it is enough to start breathing air enriched with oxygen, stop smoking, drink enough water and normalize your lifestyle.

    Also, with a strong increase in hematocrit, it is necessary to consult a doctor for prescribing blood thinners - anticoagulants.
