The United States is not the only country where binge drinking and binge eating are a problem. But Americans face a unique crisis. The country’s obesity and diabetes epidemics, combined with excessive alcohol consumption, are making more people sick with a liver disease that until recently had no name.
Metabolic dysfunction and alcohol-related liver disease (MetALD) is now a top concern among physicians in the United States, as more young people and women face serious illness and die from the condition. Doctors worry that more Americans are silently developing MetALD, at least in part because many people don’t realize they’re drinking too much.
MetALD occurs in people who have liver fat, metabolic risk factors (obesity, prediabetes or diabetes, high blood pressure, high cholesterol), and who drink 10 or more alcoholic drinks per week for women and 15 or more for men.
According to several studies, the percentage of Americans who meet these criteria has more than doubled since 1990. According to a recent JAMA Internal Medicine study, nearly 1 in 10 U.S. adults report an overlap between heavy drinking and obesity.
MetALD is now nearly twice as common as alcohol-related liver disease, and its risk factors affect younger people. People ages 26 to 34 have the greatest overlap in alcohol use disorder and obesity of any age group, national survey data shows.
“Drinking alcohol causes fat to accumulate in the liver,” says liver researcher and liver transplant specialist Juan Pablo Arab. “But what if you already have obesity and insulin resistance and have fat buildup in your liver?”
This is a bad combination, Arab doctors told STAT. More than one-third of Americans are thought to have problematic levels of fat accumulation in their livers, commonly known as fatty liver disease. One-third of adults also meet criteria for MASLD, a fatty liver disease associated with metabolic dysfunction, formerly known as nonalcoholic fatty liver disease.
