Ascites - Market Insight, Epidemiology, and Market Forecast - 2036

Ascites Insights and Trends

• The Ascites market is expected to witness steady growth across the major markets, with the United States leading in market size, followed by the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan during the study period.
• A significant proportion of the Ascites burden is concentrated among adults, particularly males and individuals with advanced chronic liver disease, underscoring the need for earlier detection of liver dysfunction, timely diagnosis of portal hypertension and fluid accumulation, improved access to effective disease management, and targeted interventions to reduce complications, hospitalizations, and mortality.
• The treatment of Ascites primarily involves sodium restriction, diuretics such as spironolactone and furosemide, large-volume paracentesis with albumin replacement, and management of the underlying liver disease to control fluid accumulation and prevent complications, while transjugular intrahepatic portosystemic shunt (TIPS) and liver transplantation remain important options for patients with refractory ascites despite limitations related to procedural risks, cost, donor availability, and patient eligibility.
• Currently, there are no approved disease-modifying therapies specifically for Ascites, and treatment primarily relies on diuretics, sodium restriction, paracentesis, and management of underlying liver disease.
• The pipeline remains limited, with a few emerging therapies under development, including Terlipressin (BIV-201), Docarpamine (CIQUAAX), and PHIN-214, among others. These investigational agents are being evaluated for their potential to improve circulatory dysfunction, renal perfusion, and fluid balance, addressing significant unmet needs in patients with refractory or advanced ascites.

Key Factors Driving the Ascites Market

• Rising Ascites Prevalence

The increasing prevalence of ascites is a key driver of market growth, fueled by the expanding burden of chronic liver diseases, including alcohol-associated liver disease, viral hepatitis, and metabolic dysfunction-associated steatotic liver disease (MASLD). The growing incidence of hepatic decompensation, particularly among male patients and the aging population, is expected to increase the demand for effective ascites management and treatment options.

Emerging Ascites Competitive Landscape

The emergence of novel therapies such as terlipressin (BIV-201), docarpamine (CIQUAAX), PHIN-214, and other investigational agents is expected to be a key driver of the Ascites market. With no FDA-approved disease-modifying therapies currently available for ascites, developers have a significant opportunity to establish the first targeted treatment in this high-unmet-need space. Companies that successfully demonstrate clinical benefit and secure regulatory approval could gain substantial first-mover advantages, including early market penetration, strong physician adoption, premium pricing potential, and leadership in a largely untapped therapeutic landscape. As a result, increasing clinical development activity is expected to intensify competition and stimulate market growth over the forecast period.

Ascites Understanding and Treatment Algorithm

Ascites Overview and Diagnosis

Ascites is a clinical condition characterized by the abnormal accumulation of fluid within the peritoneal cavity, most commonly resulting from underlying liver disease such as cirrhosis, portal hypertension, malignancies, heart failure, or infections. The condition develops due to imbalances in hydrostatic and oncotic pressures, along with sodium and water retention, leading to progressive fluid buildup in the abdomen. Ascites is most frequently associated with advanced chronic liver disease but can occur across a wide range of underlying systemic and intra-abdominal disorders. It primarily affects individuals with chronic hepatic conditions, alcohol-related liver injury, viral hepatitis, or malignancy, with severity influenced by the progression of the underlying disease and associated complications.

Ascites is diagnosed through clinical examination supported by imaging and Ascitic fluid analysis. Key investigations include abdominal ultrasound and diagnostic paracentesis with fluid studies (SAAG, protein, cell count, and culture), along with liver and renal function tests to identify the underlying cause and guide management.

Ascites Treatment

The primary goals of ascites treatment are to reduce fluid accumulation, relieve symptoms, prevent complications, improve quality of life, and manage the underlying cause of portal hypertension or liver disease. Management typically includes dietary sodium restriction, fluid management, and diuretic therapy with agents such as spironolactone and furosemide. Large-volume paracentesis with albumin infusion is commonly used for tense or refractory ascites, while antibiotics may be administered for spontaneous bacterial peritonitis. In patients with refractory disease, TIPS can help reduce portal pressure and control fluid recurrence. Liver transplantation remains the only definitive treatment for patients with decompensated cirrhosis and recurrent or treatment-resistant ascites.

Ascites Unmet Needs

The section “unmet needs of Ascites” outlines the critical gaps between the current state of patient care, diagnosis, and the ideal & effective management of the disease. It highlights the obstacles experienced by patients, clinicians, and researchers and identifies potential solutions for future progress.

• Late and under-diagnosis of early-stage ascites
• Lack of reliable non-invasive diagnostic biomarkers
• Poor long-term control of recurrent or refractory ascites
• Limited options for diuretic-resistant patients, and others…..

Ascites Epidemiology

Key Findings from Ascites Epidemiological Analysis and Forecast

• The total prevalent cases of Ascites due to cirrhosis across the 7MM is expected to increase throughout the study period (2022-2036), driven by the growing burden of chronic liver diseases, increasing rates of alcohol-related liver injury, MASLD, viral hepatitis, and improved survival of patients with advanced cirrhosis.
• Among the 7MM, the United States has the highest prevalent cases of Ascites in 2025 due to cirrhosis.
• Among the EU4 & UK, Germany reported the highest prevalent cases of Ascites, followed by UK and France. Spain was found to have the least cases in 2025 among all European countries.
• In 2025, Malignant Ascites cases are calculated from ovarian cancer, stomach cancer, breast cancer, and colorectal cancer. Breast cancer accounted for the highest number of prevalent cases of Ascites from these cancers in the United States.
• The observed male predominance and earlier onset of Ascites highlight the importance of timely identification and management of underlying liver disease, targeted risk-reduction strategies, and early intervention to prevent disease progression and associated complications.
