In some cases, a person needs to be attentive to his health, tracking the work of organs and systems. Also important is the control of blood characteristics. After all, this fluid performs many functions in the body, and violations in its composition adversely affect the overall well-being and can cause the development of various kinds of diseases. So a rather serious pathology is impaired blood viscosity, consider on
Blood viscosity is normal
You can not talk about violations of blood viscosity, not having information about what this indicator should be normal. To determine the viscosity of the blood take into account many data – the number of red blood cells in the blood (normally from 3.9 to 5.1). Also taken into account is the amount of prothrombin and the amount of fibrinogen (from 2 to 4g / l). Some experts conduct a special test for viscosity, comparing the rate of advancement of blood and distilled water. To do this, use a special device – a viscometer. In this study, the rate of blood viscosity: 4.3-5.4 divisions of the scale for men and 3.9-4.9 divisions for women.
There is evidence that the viscosity of blood in women is much lower than in men. This difference is due to physiological features and hormonal background.
The level of blood viscosity is determined by the percentage of red blood cells in the blood. So an increase in the number of these elements is accompanied by an increase in viscosity and vice versa.
Reduced blood viscosity. The reasons
The reason for reduced blood viscosity is a decrease in the number of red blood cells. This process can be observed with anemia, kidney dysfunction and lack of protein in the blood. Also, such a violation occurs with reduced blood clotting, during the period of gestation of the child, and even with anemia. The number of red blood cells (as well as blood viscosity) decreases with prolonged therapy with heparin or aspirin.
Symptoms of reduced blood viscosity
The decrease in blood viscosity leads to the fact that it actively flows through the blood vessels. If a decrease in viscosity is accompanied by coagulation disorders, a patient may experience bleeding of various types that are difficult to stop. Patients may experience subcutaneous hemorrhage, hemorrhage into the joints and other similar disorders.
Increased blood viscosity. The reasons
It is extremely rare for people to come into the world with an over-viscosity syndrome. In most cases, the increase in blood density is triggered by various pathological conditions occurring in the body. Diseases can change the amount of proteins, red blood cells and plasma in the blood, increasing blood viscosity. Among such ills are problems in the activity of the gastrointestinal tract, triggered by toxic food poisoning. The viscosity of human blood can increase with an increase in the volume of carbon dioxide in the blood, which is characteristic of hypoxia. Also, such a violation can be explained by a pathological increase in the number of erythrocytes in the blood (polycythemia), leukemia (blood cancer), excess protein in the blood (Waldenstrom macroglobulinemia), diabetes mellitus and adrenal dysfunction. There is evidence that blood viscosity can increase with hepatitis, pregnancy, chemical and thermal burns and varicose veins.
Blood coagulation occurs with a lack of moisture in the body, with insufficient nutrition, consumption of environmentally contaminated products. Also, such a pathology can be provoked by damage to the blood vessels, strong acids (the final product of protein breakdown, which is not fully eliminated from the body), deficiency of mineral and vitamin substances, hyperfunction of the spleen, etc.
How the increased blood viscosity manifests itself (symptoms of an increase)
Unfortunately, excessive blood viscosity may not be felt for a long time. Patients with a similar disorder may complain of a severe headache, numbness of the extremities for no apparent reason. They may also have an irregular heartbeat. In some cases, an increase in blood viscosity can cause fainting and nausea. When such symptoms appear, it is best to seek doctor’s help.
Too thick blood can cause the development of chronic fatigue syndrome, the main manifestations of which are weakness and severe malaise.
Many patients with such a disorder complain of an increase in blood pressure, they are worried about drowsiness, a feeling of dry mouth. Also, with high blood viscosity, depressive states can develop. The extremities of such patients are cold, and nodules may appear on the veins. Many patients also note the occurrence of unpleasant heaviness in the legs.
To determine the level of blood viscosity, specialists conduct appropriate laboratory tests. In most cases, patients are sent to a coagulogram.
In the event that an increase in blood viscosity is temporary, the symptoms of the disorder disappear very quickly.
If you suspect a violation of blood viscosity, you should quickly contact a doctor. In the absence of timely correction, such pathologies can cause serious harm to health and even carry a threat to life.
