The Rising Tide of MASLD: A Looming Health crisis in the US
New research is painting a concerning picture of the future of metabolic dysfunction-associated steatotic liver disease (MASLD) in the United States.A recent decision analytical modeling study projects that by 2050, the prevalence of MASLD will reach a staggering 41.4%,affecting approximately 122 million americans. This alarming forecast underscores the urgent need for effective treatments and strategic planning to address the growing clinical burden of this progressive liver disease.
The Growing Burden of MASLD
The study, led by Phuc Le, PhD, MPH, associate staff at Cleveland Clinic Community Care and assistant professor of medicine at Cleveland Clinic Lerner College of Medicine, highlights the escalating prevalence of MASLD and its complications. “Understanding the clinical burden of MASLD, especially the number of patients eligible for pharmacologic treatment, could enable health systems and pharmaceutical companies to prepare to meet imminent demand, but estimates vary widely, posing planning challenges,” Le and colleagues noted.
The research utilized an agent-based state transition model to simulate the natural progression of MASLD from 2020 to 2050. The model incorporated data from the US census Bureau and life tables, reflecting the age and sex distribution of the US population. It also accounted for births,immigration,and mortality rates to ensure accuracy.
Key Findings
The study revealed a steady increase in MASLD cases, rising from 33.7% (86.3 million peopel) in 2020 to 41.4% (121.9 million people) by 2050. Additionally, cases of metabolic dysfunction-associated steatohepatitis (MASH), a more severe form of MASLD, are projected to grow from 5.8% (14.9 million people) in 2020 to 7.9% (23.2 million people) by 2050.| Key Metrics | 2020 | 2050 |
|——————————–|————————|————————|
| MASLD Prevalence | 33.7% (86.3 million) | 41.4% (121.9 million) |
| MASH Prevalence | 5.8% (14.9 million) | 7.9% (23.2 million) |
| Fibrosis Stage F0 | 48.4% | – |
| Fibrosis Stage F1 | 29.1% | - |
The Role of Pharmacologic Treatments
On March 14, 2024, resmetirom (Rezdiffra) became the first-ever FDA-approved liver-directed MASH therapeutic. While this marks a significant milestone, it remains the only approved pharmacologic option for treating MASLD. Other molecules are currently in clinical development, but the lack of effective treatments poses a significant challenge for healthcare systems.
Implications for Health Systems
The study’s findings emphasize the need for proactive measures to address the impending surge in MASLD cases. Health systems and pharmaceutical companies must prepare for the growing demand for treatments and interventions. Understanding the clinical burden of MASLD, including the number of patients eligible for pharmacologic treatment, is crucial for effective planning and resource allocation.
A Call to Action
As the prevalence of MASLD continues to rise, it is imperative for stakeholders to collaborate on developing innovative solutions. from advancing pharmacologic treatments to implementing preventive strategies,addressing this looming health crisis requires a multifaceted approach.

by 2050, the United States is projected to face a significant surge in cases of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), with advanced stages of the disease becoming increasingly prevalent. A recent decision analytical modeling study published in JAMA Network Open reveals alarming trends, estimating that the burden of MASLD will escalate dramatically over the next three decades.
The Growing Burden of MASLD
In 2020, 14.5% of individuals with MASLD had F2 fibrosis, 5.7% had F3 fibrosis, and 2.2% had F4 fibrosis, the most severe stage. By 2050,these numbers are expected to rise sharply,with projections showing 17.4% at F2, 8.4% at F3, and 4.0% at F4.This progression underscores the urgent need for preventive measures and enhanced healthcare strategies.
The study also highlights a staggering 75% increase in the population with MASH (Metabolic Dysfunction-Associated Steatohepatitis) and ≥ F2 fibrosis, jumping from 6.7 million in 2020 to 11.7 million in 2050. investigators noted that the prevalence of fibrosis stages is climbing, with higher rates observed in more advanced cases.
A Call to Action
“This decision analytical modeling study estimates a considerable burden of MASLD in the next 30 years in the US,” the investigators concluded. “By implementing preventive strategies, investing in research, and preparing health care systems, we can minimize the impact of MASLD and improve the lives of millions of individuals affected by this disease.”
The findings emphasize the critical importance of early intervention and robust healthcare planning. Without decisive action,the escalating prevalence of MASLD could place an unprecedented strain on the US healthcare system.
Key Projections at a Glance
| Fibrosis Stage | 2020 Prevalence | 2050 Projected Prevalence |
|—————-|—————–|—————————|
| F2 | 14.5% | 17.4% |
| F3 | 5.7% | 8.4% |
| F4 | 2.2% | 4.0% |
The Path Forward
The study’s authors advocate for a multi-pronged approach to combat this growing epidemic. Preventive strategies, such as promoting healthier lifestyles and early screening, are essential. Additionally, increased investment in research and the development of effective treatments, like the recently FDA-approved Resmetirom (Rezdiffra) for noncirrhotic NASH, could play a pivotal role in mitigating the disease’s impact.
as the US braces for this impending health crisis, the time to act is now. By addressing MASLD proactively, we can safeguard the health of millions and alleviate the future burden on our healthcare systems.
