AI Summary Nearly 80% of ascites cases occur in people with cirrhosis, and treatment aims to relieve symptoms with less dietary salt, diuretics, and fluid drainage when needed.

Ascites

Medically reviewed.

Ascites is the abnormal buildup of fluid in the abdomen. It is not a disease on its own. It is a symptom of another condition, most often advanced liver disease and cirrhosis. Treatment aims to relieve symptoms and may include less salt in the diet, diuretic medicines, and draining the extra fluid.

This page explains how ascites is treated, who may need each option, and what follow-up care looks like. You can also connect with a liver specialist to discuss which approach fits your care plan.

ASCITES TREATMENT OVERVIEW

What Is Ascites and Who May Benefit From Treatment

Ascites is the abnormal buildup of fluid in the lining of the abdomen and the organs around it. Nearly 80% of cases occur in people with cirrhosis. Two problems in the liver cause the fluid to collect: portal hypertension (high blood pressure in the blood vessels of the liver) and low levels of a protein called albumin. Small amounts of fluid can be hard to notice. As more collects, the abdomen looks larger, and bloating, discomfort, and weight gain can follow.

The goal of treatment is to relieve symptoms. Care typically combines less salt in the diet, diuretic medicines that remove extra water, and, when fluid keeps returning, draining the fluid. The right plan depends on the cause of the ascites, how much fluid builds up, and your overall health. A liver specialist can help you understand which options fit your care plan.

Aldactone (Spironolactone)

Aldactone is a prescription diuretic used as a first-line treatment for ascites caused by cirrhosis and portal hypertension. It blocks aldosterone, a hormone that makes the body hold on to sodium and water, and it helps the body keep potassium. Many people take it long term.

Lasix (Furosemide)

Lasix is a prescription loop diuretic that helps the kidneys remove extra sodium and water. Providers often prescribe it together with Aldactone to improve fluid removal and keep electrolytes in balance.

Large-Volume Paracentesis

Large-volume paracentesis is a minimally invasive procedure that drains a large amount of fluid from the abdomen, typically more than 5 liters in one session. It brings fast relief from pressure and trouble breathing. Intravenous albumin may be given afterward to help protect circulation and kidney function.

Who may benefit

Providers may consider ascites treatment for adults with cirrhosis or advanced liver disease who have fluid buildup in the abdomen. Less salt and diuretic medicines are usually the starting point. Draining fluid may be an option when ascites causes pain, bloating, or trouble breathing, or when medicines do not control it. Your care team decides based on your diagnosis, symptoms, and test results.

DIET & LIFESTYLE SUPPORT

How Lifestyle Changes Support Ascites Treatment

Ascites treatment works best when combined with daily habits. Eating less salt, taking medicines consistently, tracking your weight, and avoiding alcohol all help control fluid buildup.

Low-sodium diet

Sodium attracts water, so too much salt can lead to more fluid buildup. A low-sodium diet favors fresh vegetables, fruits, lean proteins, whole grains, herbs, and spices over processed, packaged, canned, and restaurant foods. Ask your care team what sodium limit is right for you.

Fluids and medicines

Your care team may ask you to limit how much fluid you drink. Follow your fluid plan and take diuretics consistently, exactly as directed.

Daily weight and alcohol

Track your body weight and belly size each day, and share changes with your care team. Avoid alcohol, which can damage the liver further.

Support your diet alongside treatment

A nutrition bar designed for liver health can be a simple, consistent way to help meet your daily energy and protein goals while you follow a low-sodium eating plan.

CAUSES, SYMPTOMS, AND COMPLICATIONS

Understanding Ascites: Causes, Symptoms, and Complications

Ascites is a sign that something else is wrong, most often advanced liver disease. Knowing the cause helps your care team choose the right treatment, because prevention also depends on the cause.

Ascites can develop slowly or suddenly. A small amount of fluid may cause no symptoms, while a large amount can cause pain, swelling, and trouble breathing.

Common causes

Portal hypertension (high blood pressure in the blood vessels of the liver) and low albumin levels cause most ascites. Cirrhosis is the most common underlying condition. Other causes include chronic infections such as hepatitis C, prolonged and excessive alcohol use, certain cancers, congestive heart failure, pancreatitis, kidney dialysis, and blood clots in the veins of the liver.

Symptoms

Bloating, abdominal pain, a sense of fullness, and weight gain increase as fluid collects. Other signs include ankle or leg swelling, nausea, decreased appetite, fatigue, indigestion, and changes to the navel. Large amounts of fluid can cause shortness of breath.

Infection risk

Ascites fluid can become infected. This infection, called spontaneous bacterial peritonitis, needs early treatment with the right antibiotics. Left untreated, it can be fatal and can greatly affect kidney function. Ask your care team which warning signs to watch for.

How ascites is diagnosed

A physical exam can diagnose moderate to severe ascites. Providers may also use ultrasound, kidney and liver function tests, urinalysis, or a 24-hour urine collection. In some cases, they remove a small sample of fluid with a needle (paracentesis) and test it for other conditions.

TREATMENT MONITORING

Monitoring Your Health During Ascites Treatment

Regular monitoring helps your healthcare provider see how your body is responding to ascites treatment and catch problems early. Follow-up care typically includes weight checks, blood pressure checks, and lab tests.

Blood tests

Kidney function and electrolyte levels, including potassium, are checked regularly while you take diuretics. These tests help your provider adjust treatment and spot problems such as dehydration or low or high potassium.

Weight and blood pressure

Your care team tracks body weight, belly size, and blood pressure to judge how well treatment is removing fluid. Daily weights at home give your team useful information between visits.

After fluid removal

After a large amount of fluid is removed, blood pressure, kidney function, and symptoms may be monitored. Most people go home the same day unless extra monitoring is needed.

Only a qualified healthcare provider can adjust your treatment plan based on your test results and health history.

COMMON QUESTIONS

Answers to Common Ascites Questions

What is ascites and why does it happen?

Ascites is a buildup of fluid in the abdomen, most often caused by advanced liver disease and cirrhosis. It is a sign of another condition, not a disease on its own. High pressure in the liver's blood vessels (portal hypertension) and low albumin levels cause most cases. Other causes include hepatitis C, prolonged and excessive alcohol use, certain cancers, and congestive heart failure. Ask your liver specialist what is causing it in your case.

What symptoms should I look for with ascites?

Common symptoms include bloating, abdominal pain, a sense of fullness, and weight gain. Some people also notice ankle or leg swelling, nausea, decreased appetite, fatigue, indigestion, or changes to the navel. A small amount of fluid may cause no symptoms, while a large amount can cause shortness of breath. Symptoms can develop slowly or suddenly. Tell your care team about any of these changes so they can look for the cause.

How do doctors usually treat ascites fluid buildup?

Treatment aims to relieve symptoms, and the plan depends on the cause and how much fluid you have. Options include eating less salt, limiting fluids if your care team advises it, and taking diuretics such as Aldactone (spironolactone) and Lasix (furosemide). Fluid can also be drained with paracentesis. Rarely, a shunt is placed to help blood flow through the liver. Your liver specialist can explain which options fit your care plan.

Does a low-sodium diet help with ascites?

Yes, eating less sodium is a key part of ascites care. Sodium attracts water, so too much salt can lead to more fluid buildup. A low-sodium diet favors fresh vegetables, fruits, lean proteins, and whole grains over processed, canned, and restaurant foods. Diet works alongside diuretics and other treatment, not in place of them. Ask your care team what sodium limit is right for you.

When do doctors drain fluid from the abdomen?

Doctors may drain fluid when ascites is tense or severe, causes pain or trouble breathing, or is not controlled by diuretics. The procedure, called large-volume paracentesis, removes fluid through a needle or catheter after the skin is numbed. It usually takes about 20 to 60 minutes, and intravenous albumin may be given afterward to support circulation. Most people go home the same day. Ask your provider whether it fits your situation.

What side effects can ascites treatment cause?

Side effects vary by treatment. Aldactone can raise potassium levels and cause dizziness, fatigue, muscle cramps, and breast tenderness or enlargement. Lasix can cause dehydration, low potassium, low blood pressure, and increased urination. Paracentesis carries risks of bleeding, infection, low blood pressure, and fluid leakage from the puncture site. Your provider monitors your kidney function and electrolytes to catch problems early. Tell your care team about new symptoms before changing any medicine.

When should I call my care team about ascites?

Contact your care team as soon as your belly swells faster, your weight climbs, your pain gets worse, or you have trouble breathing. Ascites fluid can become infected, which is called spontaneous bacterial peritonitis. This infection needs early treatment with the right antibiotics and can greatly affect kidney function. Do not wait for your next scheduled visit. Ask your team which warning signs matter most for you.
