Gradually low blood pressure in patients with cirrhosis is generally abnormal. Anemia, massive ascites, etc. may be present, and patients are advised to seek prompt medical attention to find out the cause. 1. In cirrhosis of the liver, if anemia occurs, including vomiting blood, blood in stool, fecal occult blood and other forms, resulting in low blood pressure due to insufficient effective blood volume. 2. Patients with large amounts of ascites have low blood pressure due to high intra-abdominal pressure, which leads to obstruction of lymphatic return and insufficient effective circulating blood volume in the arterial and venous blood vessels. Due to the reduction of the effective circulating blood volume, it is not possible to form a certain pressure on the walls of the blood vessels. In addition, the pathological mechanism of liver cirrhosis can simultaneously affect the normal function of multiple organs (such as gastrointestinal, kidney, etc.), which can lead to abnormalities in hormone metabolism (such as renin angiotensin aldosterone system), and due to the combination of factors such as prolonged bed rest, hyponatremia and so on, low blood pressure will often occur. It is recommended that patients seek timely medical attention to identify the cause and treat the cause, while closely monitoring blood pressure.
