Definition

Ascites is the buildup of excess fluid in the abdominal cavity.

Ascites

Causes

Ascites can be caused by:

Cirrhosis (most common cause)
High blood pressure in the liver's portal venous system
Poor nutrition or other health problems that lead to low amounts of protein in the blood
Certain cancers
Infections from bacteria, parasites, or tuberculosis
Pancreatitis
Kidney disease
Lymph fluid leaking from the abdomen

Risk Factors

The risk of this problem is higher in people who have any of the health problems that cause ascites.

Treatment

The underlying cause will need to be treated. The goal of treatment is to ease symptoms. Options are:

Dietary Changes

Dietary changes may need to be made, such as:

Limiting sodium to ease fluid buildup
Limiting fluids if sodium levels are too low
Avoiding alcohol, which can impair liver function

Medicine

Diuretic medicines cause the kidneys to pass more sodium and water in urine. They may be used with a low sodium diet.

Procedures

Excess fluid may need to be removed. This can be done with paracentesis. A hollow needle will be inserted in the abdomen to remove the fluid.

People who are not helped by these methods may need:

Surgery to direct blood away from the liver
A liver transplant

Prevention

The risk of this health problem may be lowered by treating or preventing the health problems that cause it.
