If the patient’s whole blood viscosity is found to be high in the high cut, medium cut and low cut, then it suggests that the blood viscosity is increased, which is often related to insufficient water intake and high blood lipids and other factors. High cut, medium cut and low cut of whole blood viscosity are the classification indexes of blood viscosity, if all three are high, it often shows that the patient’s blood viscosity is increased, the patient should drink more water, and at the same time, need to further check the blood lipids, to make clear whether there is any dyslipidemia. Long-term high blood lipid is easy to affect the patient’s blood vessels, the patient should control the diet, eat less fat meat, vegetable oil and animal oil, and usually pay attention to a light diet. If the blood fat is at a higher level for a longer period of time, the patient can also take medication such as simvastatin tablets to lower the blood fat as prescribed by the doctor. When the blood viscosity increases, patients also need to control their weight, strengthen exercise, and usually pay attention to avoid drinking and smoking. It is recommended that patients go to the hospital in time, under the guidance of physicians.
