What is one cause of ascites?

Ascites refers to the abnormal accumulation of fluid in the abdominal cavity, and one of its primary causes is fluid accumulation resulting from liver failure. When the liver fails, there is often an increase in portal hypertension, which is elevated blood pressure in the portal venous system. This increased pressure can lead to an overflow of fluid into the abdominal cavity, resulting in ascites.

Additionally, liver failure can disrupt the production of proteins like albumin, which helps to maintain oncotic pressure in the blood vessels. A decrease in albumin levels can lead to fluid leaking out of the blood vessels and into surrounding tissues and cavities, contributing further to the development of ascites. This connection between liver function and fluid balance illustrates why fluid accumulation from liver failure is a significant cause of ascites.
