Blood thickening is also known as blood thickening, that is, the increase of blood viscosity. After the increase of blood viscosity, it is easy to have slow blood flow and high viscosity blood disorder, and it is easy to form thrombosis and embolic diseases, so it is necessary to drink more water to dilute the blood properly after the blood thickening, and at the same time, it is necessary to avoid high-fat and high-sugar food and pay attention to a light diet. At the same time, it is also necessary to carry out corresponding treatment for the causes of increased blood consistency. For example, if the increased blood consistency is caused by increased blood cells, such as increased red blood cells, increased platelets and increased white blood cells, the most effective method in this case is to use a blood cell separator to separate out the excessive blood cells so that the blood consistency will gradually decrease. At the same time, if the increase of blood viscosity is caused by high blood sugar and high blood lipid, it is necessary to give blood sugar and blood lipid lowering treatment.
