Low viscosity refers to low blood viscosity, which may be related to daily diet, but also can be seen in anemia and other diseases. 1. Casone viscosity is a hemodynamic index, which can reflect the viscosity of blood. The value of casone viscosity can indirectly reflect certain diseases and has certain significance in the diagnosis of diseases. The correlation between the viscosity of Kasson and the viscosity of whole blood is significant, and it is also related to the deformability of red blood cells. A low viscosity of Kasson also means a low viscosity of blood. 2. For patients with coronary heart disease, hypertension and other cardiovascular diseases, low blood viscosity is beneficial, but low blood viscosity can also be seen in anemia and other diseases, which need to be analyzed according to the specific clinical situation. Low viscosity may also be related to daily diet, it is recommended to pay attention to low-salt, low-fat diet, and properly strengthen the body aerobic exercise. The low viscosity of kasone generally does not have a great impact on the body, and will not cause serious consequences, but it is recommended that the patient consult a regular hospital in a timely manner, improve the examination, please doctor’s clear diagnosis and analysis.
