What are the causes of high blood viscosity?

When people have problems with high blood viscosity, most of the reasons are because the cell concentration is too high or the body's fat nutrition content is relatively rich. In this case, the problem of high blood viscosity may occur. In addition, the human body's capillaries are very thin, which is also a cause of high blood viscosity.

① The cell concentration is too high: the number of cells in the blood increases relatively. For example, the water content in the body of the elderly is relatively reduced, and the water content in the blood also decreases, so the proportion of blood cells will be relatively increased. As the liquid component in the blood decreases and the solid component increases, the viscosity of the blood will naturally increase.

② Increased blood viscosity: In addition to red blood cells, the blood also contains many plasma proteins, such as globulin, fibrinogen, etc. When these large molecular proteins increase in number, they often adhere to red blood cells to form a grid, increasing the resistance to blood flow and causing increased blood viscosity.

③ Increased aggregation of blood cells: The cells in the blood should perform functions individually rather than aggregate together. When there is some abnormality in the structure of red blood cells or platelets, the red blood cells and platelets will accumulate together, blocking blood vessels and forming blood clots.

④ The deformability of blood cells is weakened: The capillaries in the human body are very thin, and the smallest blood vessel can only allow one blood cell to pass through. Moreover, blood cells have to change their shape when passing through small blood vessels to facilitate passage. When the deformability of blood cells is weakened, it is difficult for them to pass through small blood vessels, affecting the blood flow rate and thus increasing blood viscosity.

⑤ Abnormal blood lipids: Since blood circulates throughout the body, when the lipid content in the blood is too high, the blood's own viscosity can change. In addition, increased blood lipids can inhibit fibrinolysis and further increase blood viscosity. Increased blood viscosity is conducive to the occurrence of coronary heart disease and may even induce acute myocardial infarction.
