High coagulation means that the blood has increased viscosity and is prone to the symptoms of clotting, as well as to complications of thrombosis and embolic diseases. In clinical practice, the common causes of high coagulation are: a. Increased blood cell count caused by an increase in the number of red blood cells, an increase in the number of white blood cells or an increase in the number of platelets can cause an increase in blood viscosity, slowing blood flow and producing hypercoagulability, which can easily lead to thrombotic disorders. For this condition, the most effective way is to apply a blood cell separator to separate out the excessive blood cells, which can quickly relieve the symptoms of high blood clotting. Second, hypertension, hyperlipidemia and hyperglycemia patients, due to high blood lipid and hyperglycemia lead to the increase of blood lipid and blood sugar content in the plasma, there will also be an increase of blood viscosity, but also easy to complicate thrombosis and embolic diseases, the most effective treatment is drug therapy blood sugar, reduce blood sugar, blood lipid. Third, it can be seen in certain neoplastic diseases, such as acute promyelocytic leukemia and multiple myeloma patients, as these two diseases tend to produce an obvious hypercoagulable state, there will also be increased blood coagulation.
