Metabolic Dysfunction–Associated Steatotic Liver Disease (MASLD), commonly known as fatty liver disease, is now the leading cause of chronic liver disease in the United States. It affects nearly one-third of American adults and up to 70% of those with type 2 diabetes, often without causing noticeable symptoms until the disease has progressed significantly.

Why it matters

As treatments for hepatitis C have improved, MASLD has become the primary driver of cirrhosis and liver transplants, surpassing alcohol-related liver disease. This silent condition is linked to metabolic syndrome and increases the risk of cardiovascular disease, stroke, and kidney issues.

The details

MASLD is caused by the buildup of fat in the liver, which can lead to inflammation and scarring over time. It is closely tied to obesity, diabetes, high blood pressure, and other metabolic factors. Many people with MASLD feel completely well, even as the disease advances, making it difficult to detect until serious complications arise.

  • MASLD is now the leading cause of chronic liver disease in the United States.
  • About one-fifth of those with fatty liver will develop inflammation and progressive scarring over time.
  • Hepatitis C-related cirrhosis has declined significantly with the availability of curative treatments.

The players

Metabolic Dysfunction–Associated Steatotic Liver Disease (MASLD)

The most common cause of chronic liver disease in the United States, also known as fatty liver disease.

Metabolic Syndrome

A cluster of conditions including abdominal obesity, high blood pressure, elevated blood sugar or diabetes, high triglycerides, and low HDL cholesterol. More than one in three U.S. adults meet the criteria for metabolic syndrome.

What’s next

Simple blood work, platelet counts, and validated scoring systems can help identify patients at risk for advanced MASLD, allowing for closer monitoring and early intervention through weight loss, improved blood sugar control, and increased physical activity.

The takeaway

MASLD, or fatty liver disease, has emerged as the leading cause of chronic liver disease in the U.S., surpassing alcohol and hepatitis, due to its strong link to the growing prevalence of obesity, diabetes, and metabolic syndrome. Early detection and management of this silent condition are crucial to preventing the development of cirrhosis and other serious complications.
