What are the main causes of ascites

summary

I believe everyone should know that liver ascites is a serious symptom of late cirrhosis, and it does great harm to people, so we must treat it in time. If we want to treat liver ascites in time, the first thing we need to do is to find out the cause of liver ascites, so as to better treat it. Now I will introduce the main causes of liver ascites to you

What are the main causes of ascites

1. The main causes of ascites are as follows: (1) the decrease of plasma albumin: the plasma albumin is synthesized by hepatocytes, and the synthesis of albumin is significantly reduced due to the dysfunction of hepatocytes in cirrhotic patients, resulting in the decrease of plasma colloidal osmotic pressure. With the involvement of portal hypertension, part of plasma infiltrates into abdominal cavity from portal vein to form ascites. It is generally considered that plasma albumin 30g / L is a critical value, and ascites often occurs when albumin 30g / L. 　　

2. The main cause of liver ascites (2) increased portal pressure: it is now clear that when liver cirrhosis, intrahepatic fibrous tissue hyperplasia, causing intrahepatic vascular obstruction, resulting in increased portal pressure, coupled with the decrease of plasma colloid osmotic pressure, makes the fluid in the portal system more easily infiltrate into the abdominal cavity. 　　

3. The main causes of liver ascites (3) increased lymph leakage: the regenerative nodules in cirrhosis can cause retrosinusoidal hepatic vein obstruction, resulting in the disorder of liver lymph excretion and increased pressure, resulting in increased lymph leakage. Some lymph will undoubtedly enter the abdominal cavity and cause ascites. During the operation, lymph leakage from the hilar lymphatic plexus and subcapsular lymphatic vessels was found, and the thoracic duct was obviously thickened, sometimes equivalent to the diameter of subclavian vein. In addition, it has been found that the external drainage of lymphatic vessels can reduce the size of liver, ascites, intrasplenic pressure and stop variceal bleeding. Therefore, it has been pointed out that the formation of ascites in liver cirrhosis is related to excessive production of lymph and insufficient drainage, which is also one of the causes of ascites in liver cirrhosis.

matters needing attention

The above is a detailed introduction of the causes of liver ascites, hope to help you. Experts pointed out that there are many causes of liver ascites, but we must distinguish them clearly and find a suitable treatment. We must not treat them blindly. The most important thing is to treat them symptomatically, otherwise it will be very harmful to our health and will lead to the aggravation of the disease. I hope my reply can help you.
