Causes of thrombocytopenia in patients with liver cirrhosis: First, it may be due to the damage of liver cells and the aggravation of liver fibrosis, which leads to the decrease of thrombopoietin and secretion, so it will cause the decrease of platelet number. Second, consider hypersplenism, which is also one of the most important reasons, because patients with cirrhosis will have portal hypertension, increased resistance of portal venous system and increased portal venous blood flow will cause long-term siltation of the spleen, so there will be an increase in size, and in the late stage of the splenomegaly will turn into hypersplenism, which will cause an increase in platelet destruction, which will lead to thrombocytopenia, and at the same time, there will be a decrease in white blood cells and red blood cells, which is known as the triple systemic Decrease. Third, the bone marrow cells are inhibited, such as hepatitis virus or serum other viruses, the bone marrow cells have a certain inhibitory effect, so it will also cause thrombocytopenia. It is recommended that patients with clear presence of cirrhosis must pay attention to it and actively cooperate with the examination and treatment.
