What is Global Fatty Liver Day?

Global Fatty Liver Day, formerly known as International NASH Day, is a global public education and awareness campaign led by Global Liver Institute (GLI). Launched in June 2018, the campaign shines a spotlight on one of the world’s most urgent yet overlooked health crises: fatty liver disease.

Observed every year on the second Thursday of June, Global Fatty Liver Day brings together patients, advocates, clinicians, researchers, and policymakers worldwide to elevate awareness and drive action. In 2026, Global Fatty Liver Day will take place on June 11.

Fatty liver disease is a silent global epidemic. Because symptoms are often subtle or absent, the disease remains widely underdiagnosed and underreported, despite its rapidly growing impact. By 2030, an estimated 357 million people worldwide are expected to be living with fatty liver disease.

The burden extends far beyond the liver. More than 70% of patients also live with obesity, up to 75% have type 2 diabetes, and 20–80% have hyperlipidemia, making fatty liver disease a critical driver of cardiometabolic risk. When left unchecked, it can progress to cirrhosis, liver cancer, and the need for liver transplantation.

Global Fatty Liver Day exists to change this trajectory - by accelerating awareness, promoting early detection, and catalyzing meaningful action to improve liver health worldwide.
