High platelets are most afraid of high sugar and high fat foods such as animal fat and animal offal. 1. Platelets have the characteristics of aggregation and adhesion, which are mainly involved in the hemostasis of the body. For example, when the blood vessels are damaged, platelets will release vasoconstrictive substances and pro-coagulant substances, and they will also aggregate and adhere together to form a platelet thrombus, which can play the role of hemostasis. When platelets are high, they are prone to aggregation and adhesion, leading to thromboembolic disease. 2. Foods high in sugar may raise blood sugar and cause blood vessel walls to stiffen and thicken the blood; animal fats, animal offal and other high-fat foods are likely to cause elevation of blood lipids and thickening of the blood. Blood viscosity is more likely to occur after the aggregation of platelets, so platelet high when the most afraid of eating these foods. When the platelet is high, it is recommended to go to the hospital in time for early and regular treatment.
