how ascites cause splenomegaly

Ascites is a condition characterized by the accumulation of fluid in the peritoneal cavity. When ascites becomes severe, it can lead to the development of portal hypertension, which is an increase in blood pressure within the portal vein that carries blood from the stomach, intestines, and spleen to the liver.

Portal hypertension can lead to increased pressure within the spleen (splenomegaly) as blood flow is obstructed and redirected to the splenic vein, causing the spleen to become engorged and enlarged. This enlargement of the spleen can further exacerbate the symptoms of ascites and lead to other complications such as hypersplenism (abnormal destruction of blood cells by the spleen) and increased risk of infections.
