Which is a common cause of edema in the abdomen?

Liver disease, particularly conditions such as cirrhosis, is a common cause of abdominal edema, known as ascites. In liver disease, the liver's ability to produce proteins like albumin is compromised. Albumin helps maintain the oncotic pressure in the blood vessels, which is crucial for keeping fluids from leaking into surrounding tissues. When albumin levels drop due to liver dysfunction, fluid can accumulate within the abdominal cavity, leading to noticeable swelling or buildup. Additionally, liver cirrhosis can lead to portal hypertension, which further contributes to fluid retention and ascites. This pathophysiological mechanism clearly illustrates why liver disease is a common cause of edema in the abdomen.
