Hemodilution (Haemodilution)

Haemodilution is a condition in which the number of red blood cells in the blood decreases as a result of an increase in plasma volume. This occurs when the amount of fluid in the circulatory system increases, for example due to large amounts of fluid being injected or during pregnancy.

Hemodilution can also occur as a result of diseases such as hypersplenism, in which the spleen enlarges and removes large numbers of cells, including red blood cells, from the blood. This leads to an increase in plasma volume and a decrease in the concentration of red blood cells in the blood.

To diagnose hemodilution, the concept of hematocrit is used. Hematocrit is the ratio of the volume of blood occupied by red blood cells to the total volume of blood. Typically, the hematocrit is about 45%, but with hemodilution this figure decreases.

Hemodilution can have various consequences. First, it can lead to a decrease in the amount of oxygen carried by the blood, as red blood cells carry oxygen to the tissues. This can lead to fatigue, dizziness and other symptoms associated with a lack of oxygen in the body.

In addition, hemodilution may affect laboratory test results because it changes the concentration of various blood components. For example, with hemodilution, the hemoglobin level may appear normal, but in fact it will be reduced because the number of red blood cells is reduced.

Various methods can be used to treat hemodilution, including the administration of blood or blood substitutes. However, before deciding on treatment, it is necessary to find out the cause of hemodilution and eliminate it.

In conclusion, hemodilution is a condition in which the number of red blood cells in the blood decreases as a result of an increase in plasma volume. This can have various consequences and requires diagnosis and treatment depending on the cause.



Hemodilution is the movement of blood from plasma to tissue. This phenomenon occurs more often when the volume of fluid in the vascular system decreases, which occurs after bleeding, the use of diuretics, due to illness or surgery (transfusion of a large volume of blood), as well as in the event of collapse. However, hemodilution should be distinguished from hemocoagulation - an increase in blood clotting as a response to injury, especially to stop bleeding from damaged vessels.

During pregnancy, the water component of the blood increases. Usually all that is required is additional fluid as tissue volume increases. In most cases this does not cause negative consequences. However, if there is a tendency to excess fluid in the blood, then a woman with a child may face the following problems:

- decrease in red blood cells; - heart pathology; - increased blood pressure; - development of edema; - inflammation of organs in the abdominal cavity; - other signs of dehydration;

If any manifestations of hemodilutia occur, it is necessary to consult with specialists for diagnosis. Treatment also depends on symptoms, possible causes, and other factors. It is recommended to drink a lot of water and natural juices, control salt intake, eat enough proteins, improve the condition of joints, wear comfortable shoes, reduce the amount of cosmetics used, and pay attention to the prevention and treatment of colds.
