Ascites: Symptoms & Signs

Medically Reviewed on 11/17/2020

Ascites is the accumulation of fluid within the peritoneal cavity of the abdomen. It is not a disease by itself but is caused by a number of different conditions.

Signs and symptoms of ascites include

  • an enlarged, distended, or swollen abdomen;
  • sudden weight gain;
  • difficulty breathing when lying down; and
  • a diminished appetite.

Other associated signs and symptoms can include

Migration of the fluid across the diaphragm can lead to associated pleural effusions (fluid in the spaces around the lungs).

Causes of ascites
