Can liver abscess cause ascites? Some liver abscesses can cause ascites. Firstly, it must be understood why ascites occur. It is because the patient has poor resistance, internal infections, and is prone to worsened infections. A liver abscess involves significant energy consumption due to prolonged fever and intermittent fevers, which can reduce the liver’s capacity to synthesize albumin, leading to a decrease in colloid osmotic pressure within the blood vessels. This is accompanied by the formation of fluid accumulation in the abdominal cavity. Therefore, when a patient with a liver abscess develops ascites, there is no need to be overly anxious or nervous. Treatment can involve vigorous anti-infection measures, supplementation with albumin, and other supportive treatments to improve the symptoms and alleviate the patient's ascites, facilitating a quicker recovery.
