blood changes
Introduction
Introduction The changes in blood caused by various factors are manifested by increased blood viscosity and abnormal blood lipids. Abnormal rheological properties of the blood will cause blood circulation disorders in the body, especially blood viscosity is an important factor.

Cause of blood changes
1. High blood viscosity syndrome is caused by an increase in one or more blood viscosity factors in the body. For example, elevated plasma viscosity, increased whole blood viscosity, increased red blood cell rigidity, increased red blood cell aggregation, increased platelet aggregation, increased platelet adhesion, increased blood coagulation, and increased tendency to thrombosis. Abnormal changes in these factors will cause the body's blood circulation, especially microcirculatory disorders, leading to tissue, cellular ischemia and hypoxia.
2, low-viscosity syndrome, mainly characterized by lower blood viscosity than normal, the main cause of low-viscosity blood is red blood cell pressure reduction.

1, high blood viscosity syndrome: clinically common are ischemic cerebrovascular disease, septic shock, diabetes, pulmonary heart disease, coronary heart disease.
2, low-viscosity blood syndrome: the main manifestation of blood viscosity is lower than normal, the cause of the formation of low-viscosity blood is mainly caused by decreased hematocrit.
Diagnosis
Differential diagnosis
Mutual identification of symptoms that are easily confused by blood changes
Vascular caliber: When the blood flows in a thick blood vessel, the blood vessel diameter does not affect the blood viscosity. However, when the blood flows in the arteriole having a diameter of less than 0.2 to 0.3 mm, as long as the cutting rate is sufficiently high, the blood viscosity is also lowered as the diameter of the blood vessel is further reduced. The cause of this phenomenon is not fully understood, but it has obvious benefits to the body. If there is no such reaction, the resistance of blood flowing in small blood vessels will be greatly increased.
