What Is Ascites?
Ascites is a buildup of fluid in the abdominal cavity.
People with ascites often have painful swelling of the belly. It can be a sign that your liver disease is getting worse.
Ascites causes
Cirrhosis of the liver is the main cause of ascites. More than 50% of people with cirrhosis develop ascites within 10 years of their liver disease diagnosis.
But sometimes people with congestive heart failure, hepatitis, or cancer get ascites.
Cirrhosis or other advanced liver disease causes scarring that makes it hard for the liver to filter the blood.
Since blood can't easily flow on its normal path into the liver, pressure builds up in the blood vessels nearby. This causes high blood pressure, known as portal hypertension, around the liver.
The fluid that the liver would normally filter builds up and moves into other parts of the body. This fluid often collects in the abdominal cavity.
There may be a small amount of fluid, or there may be enough to cause the belly to swell painfully.
Risk factors and complications of ascites
Liver damage is the biggest risk factor for ascites.
Problems that cause liver damage include:
Some other conditions that increase your risk for ascites are:
- Ovarian, pancreatic, liver, or endometrial cancer.
- Heart or kidney failure.
- Pancreatitis.
- Tuberculosis.
- Hypothyroidism.
Having ascites makes it likely you'll have other complications of liver disease, such as:
- Edema (swelling of legs and ankles).
- Spontaneous bacterial peritonitis (unexplained and potentially life-threatening infection of the ascitic fluid).
- Abdominal wall hernias.
- Hepatorenal syndrome (kidney failure).
- Hepatic encephalopathy (liver fails to properly remove toxins from the body, leading to mental confusion).
- Hepatic hydrothorax (fluid that pushes into the lung cavity).
How to prevent ascites
The only sure way to prevent ascites is to keep your liver healthy.
If you have liver disease, you can prevent further damage by:
- Eating a healthy diet.
- Staying at a healthy weight.
- Not drinking alcohol.
- Seeing your liver doctor on a routine basis.
