Causes

Ascites can be caused by:

Risk Factors

Factors that may increase your chance of ascites include having any of the conditions above.

Symptoms

Symptoms may include:

Diagnosis

Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests to determine cause may include:
Imaging tests look for the amount and distribution of fluid, and evaluate abdominal structures. These may include:

Treatment

Some treatments will vary according to what is causing the ascites. Talk with your doctor about the best treatment plan for you. Some options include:

Dietary Changes

  • Sodium restriction—Limiting salt intake to 2,000 mg (milligrams) per day or fewer is often recommended to reduce or delay fluid buildup. More extreme restrictions in salt intake do not help.
  • Fluid restriction—If sodium level is too low.
  • Alcohol restriction—Ascites commonly occurs in people who have liver disease. Consuming excess alcohol can further impair liver function. Stopping alcohol use may limit the progression of ascites.

Diuretics

Diuretic medications cause the kidneys to excrete more sodium and water in the urine. These medications are often recommended as the treatment of choice for ascites, along with sodium restriction.

Paracentesis

Ascites can be treated by inserting a hollow needle into the abdomen and removing excess fluid through the needle.

Surgery

If the other treatments are not effective and the ascites keep coming back, surgery can be done to divert blood away from the liver. If this is not successful, a liver transplant may be necessary.
