Ascites is the build up of fluid in the space between the lining of the abdomen and abdominal organs (the peritoneal cavity).
Portal hypertension - ascites
Causes, incidence, and risk factors
Ascites results from high pressure in the blood vessels of the liver (portal hypertension) and low levels of a protein called albumin.
People with certain cancers in the abdomen may develop ascites. These include cancer of the colon, ovaries, uterus, pancreas, and liver.
Other conditions that can cause this problem include:
Kidney dialysis may also be associated with ascites.
Symptoms may develop slowly or suddenly depending on the cause of ascites. You may have no symptoms if there is only a small amount of fluid in the belly.
As more fluid collects, you may have abdominal pain and bloating. Large amounts of fluid can cause shortness of breath.
Many other symptoms of liver failure may also be present.
