Causes

Ascites is usually caused by liver disorders, including:

  • Cirrhosis —a disease in which the liver becomes permanently damaged
  • Chronic hepatitis —an infection of the liver
  • Severe alcoholic hepatitis without cirrhosis
  • Obstruction of the hepatic vein (a blood vessel of the liver)

It can also be caused by:

Risk Factors

These factors increase your chance of developing ascites. Tell your doctor if you have any of these risk factors:

Symptoms

If you experience any of these symptoms do not assume it is due to ascites. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include the following:

  • Ultrasound —a test that uses sound waves to examine the abdominal cavity
  • CT scan —a type of x-ray that uses a computer to make pictures of structures inside the abdominal cavity
  • MRI scan —a test that uses magnetic waves to make pictures of structures inside the abdominal cavity
  • Laparoscopy —a thin, lighted tube inserted through a small incision in the abdomen to look at the structures inside the abdominal cavity
  • Blood tests—to determine liver and kidney function as well as evidence of other problems that may lead to ascites
  • Liver biopsy —removal of a sample of liver tissue for testing
  • Angiography —x-rays taken after a dye is injected into the arteries to better view the area being examined
  • Abdominal paracentesis —removal and testing of fluid from the abdominal cavity

Treatment

Talk with your doctor about the best treatment plan for you. Treatment options include the following:

  • Sodium restriction—Limiting salt intake to 2,000 mg per day or less is often recommended to reduce or delay fluid build-up. More extreme restrictions in salt intake do not further improve outcomes.
  • Alcohol restriction—Ascites commonly occurs in people who have liver disease. Consuming alcohol can further impair liver function. Stopping alcohol use may limit the progression of ascites.

Diuretic medications are drugs that 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.

Examples of diurectics include:

  • Spironolactone (Aldactone)
  • Furosemide (Lasix)

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

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 you are diagnosed with ascites, follow your doctor's instructions .

Prevention

To decrease the risk of ascites, take the following steps to prevent cirrhosis, the most common cause of ascites:

If you have had ascites, you can prevent their reoccurrence by:

  • Not drinking alcohol
  • Limiting your use of all medications, including over-the-counter drugs (unless recommended otherwise by your doctor)
  • Restricting your sodium intake
  • Taking diuretics as recommended by your doctor
