What is Ascites?

Ascites refers to the accumulation of fluid within the peritoneal cavity, which is the space between the abdominal organs and the abdominal wall. The fluid buildup occurs as a result of underlying medical conditions and disrupts the normal functioning of the body.

Risk Factors

Several factors can increase the risk of developing ascites, including:

Liver cirrhosis or liver disease
Chronic hepatitis B or C infection
Alcohol abuse
Heart failure
Kidney disease
Certain types of cancer, such as ovarian, liver, or pancreatic cancer
Malnutrition
Blood clots in the veins of the liver
Peritoneal tuberculosis

Causes

The most common cause of ascites is liver cirrhosis, which results from chronic liver damage. Cirrhosis can be caused by excessive alcohol consumption, hepatitis infections, non-alcoholic fatty liver disease (NAFLD), or autoimmune liver diseases. Other factors, such as heart failure, kidney disease, and certain cancers, can also cause ascites.

Symptoms

Abdominal bloating and distension
Rapid weight gain
Swelling in the legs and ankles
Shortness of breath
Fatigue and weakness
Nausea and reduced appetite
Frequent urination
Indigestion and discomfort

Diagnosis

A healthcare professional will perform a physical examination to diagnose ascites, looking for signs of abdominal swelling and fluid retention. They may also conduct the following tests:

Ultrasound or CT scan to visualise the abdominal cavity and determine the amount of fluid present.
Blood tests to assess liver and kidney function, as well as other potential underlying causes.
Paracentesis is a procedure in which a fluid sample is removed from the abdomen using a needle for further analysis.

Treatment Options

The primary goals of ascites treatment are to manage the underlying cause and alleviate symptoms. The treatment options include:

Dietary Changes: Restricting salt intake can help reduce fluid retention..
Paracentesis: Draining large amounts of fluid from the abdomen can provide immediate relief.
Transjugular Intrahepatic Portosystemic Shunt (TIPS): In severe cases, a shunt can be placed to redirect blood flow and reduce pressure in the liver.
Liver Transplantation may be considered for individuals with end-stage liver disease.

Complications

If left untreated, ascites can lead to complications such as:

Spontaneous Bacterial Peritonitis (SBP): Bacterial infection in the ascitic fluid.
Hepatorenal Syndrome: Kidney failure due to severe liver disease.
Umbilical or Inguinal Hernias: Weakening of the abdominal wall leading to organ protrusion.
Hepatic Encephalopathy: Brain dysfunction resulting from liver failure.
Malnutrition: Ascites can disrupt nutrient absorption and lead to weight loss.

Who and When to Consult

If you experience persistent abdominal swelling, weight gain, or any other ascites-related symptoms, it is essential to consult a gastroenterologist. promptly. Regular monitoring is crucial if you have a known underlying condition like liver disease or heart failure to detect ascites early and manage it effectively.

How can I control Ascites?

Monitor your weight: Weigh yourself daily and contact your healthcare provider if you notice a sudden weight gain of more than 10 pounds or a consistent weight gain of more than two pounds per day for three consecutive days. Regular weight checks can help detect fluid retention early.
Limit alcohol consumption: It is advisable to avoid alcohol completely or limit its intake. Alcohol can worsen liver damage and contribute to fluid accumulation in the abdomen.
Adopt a low-sodium diet: Stick to a low-salt diet, typically restricted to 2,000 to 4,000 milligrams of sodium daily. Excess sodium can contribute to fluid retention, so limiting your intake of processed foods, canned goods, and high-sodium condiments is essential. Instead, opt for fresh fruits, vegetables, lean proteins, and foods with low sodium content.

Summary

Ascites is a condition characterised by abnormal fluid accumulation in the abdominal cavity. It can occur due to various underlying causes, most commonly liver cirrhosis. Prompt diagnosis and treatment are essential to alleviate symptoms, manage the underlying condition, and prevent complications. If you suspect ascites or have any concerning symptoms, consult a healthcare professional for a comprehensive evaluation and appropriate management.

Frequently Asked Questions

1. Is ascites life-threatening?

Yes, ascites can be life-threatening, especially if left untreated or if it progresses to severe stages. Ascites itself may not directly cause death, but it can be indicative of advanced liver disease or other serious underlying conditions. In addition, complications associated with ascites, such as spontaneous bacterial peritonitis (SBP), hepatorenal syndrome, and hepatic encephalopathy, can be life-threatening if not promptly addressed.

2. How common is ascites?

Ascites is a relatively common complication of liver cirrhosis, affecting approximately 50% of patients with advanced liver disease. It can also occur due to other conditions mentioned earlier, but its prevalence varies depending on the underlying cause.

3. Can ascites be cured?

The cure for ascites depends on successfully treating the underlying cause, such as liver cirrhosis or heart failure. If the underlying condition is manageable or reversible, the ascites may resolve. However, ascites may recur despite treatment in cases of advanced liver disease.

4. What stage of liver disease is ascites?

Ascites occurs when excess fluid collects in the abdominal cavity, often as a result of advanced liver disease, particularly cirrhosis. It signifies a progression from compensated cirrhosis, where the liver still functions adequately despite damage, to a phase where the liver’s ability to regulate fluid balance is significantly impaired.
